It shows how structural systems of a buildingsuch as an integrated assembly of elements with pattern, proportions, and scaleare related to the fundamental aspects of architectural design: formal and spatial composition, program fit, coordination with other building systems, code compliance, etc. The book is written by Francis D. K. Ching, a renowned author and professor of architecture who has published many books on architectural graphics, design, and history. He is joined by Barry S. Onouye, a professor of architecture and structural engineering who has extensive experience in teaching and practice, and Douglas Zuberbuhler, a practicing architect and educator who has worked on various projects around the world. The book features a one-stop guide to structural design in practice, a thorough treatment of structural design as part of the entire building process, and an overview of the historical development of architectural materials and structure. It is illustrated throughout with Ching's signature line drawings, which are simple yet elegant, informative yet artistic, and analytical yet expressive. The book is organized into eight chapters, each covering a major topic of structural design: - Structural Patterns - Horizontal Spans - Vertical Dimensions - Lateral Stability - Long-Span Structures - High-Rise Structures - Systems Integration In this article, we will give you a brief overview of each chapter and highlight some of the key points and examples from the book. We hope that this article will inspire you to read the book and learn more about structural design for architecture. ## Structural Patterns The first chapter introduces the concept of structural patterns and how they relate to architectural design. Structural patterns are the basic configurations of structural elements that form the framework of a building. They can be classified into four basic types: linear, planar, volumetric, and hybrid. Linear patterns consist of one-dimensional elements that span between supports or enclose spaces. Examples of linear elements are beams, columns, trusses, cables, etc. Linear patterns can be used to create different spatial compositions and effects, such as rhythm, hierarchy, directionality, continuity, etc. Planar patterns consist of two-dimensional elements that span between supports or enclose spaces. Examples of planar elements are slabs, walls, shells, membranes, etc. Planar patterns can be used to create different spatial compositions and effects, such as enclosure, division, transparency, curvature, etc. Volumetric patterns consist of three-dimensional elements that span or enclose spaces. Examples of volumetric elements are frames, boxes, domes, vaults, etc. Volumetric patterns can be used to create different spatial compositions and effects, such as volume, solidity, complexity, etc. Hybrid patterns consist of combinations of linear, planar, and volumetric elements that span or enclose spaces. Examples of hybrid elements are arches, tubes, cores, outriggers, etc. Hybrid patterns can be used to create different spatial compositions and effects, such as integration, contrast, balance, etc. The chapter shows how structural patterns can be applied to various types of buildings, such as houses, schools, offices, museums, stadiums, etc. It also shows how structural patterns can be influenced by various factors, such as site conditions, functional requirements, aesthetic preferences, cultural values, etc. ## Horizontal Spans The second chapter focuses on horizontal spans and why they are important for structural design. Horizontal spans are the distances between supports that horizontal elements have to bridge or cover. Horizontal spans affect the size, shape, and material of horizontal elements, as well as the type and location of supports and connections. The chapter discusses the three basic types of horizontal spanning elements: beams, slabs, and trusses. Beams are linear elements that span between supports and resist bending moments and shear forces. Beams can be made of various materials, such as wood, steel, concrete, etc. Beams can be classified into different types based on their cross-sections, such as rectangular, T-shaped, I-shaped, etc. Slabs are planar elements that span between supports and resist bending moments and shear forces. Slabs can be made of various materials, such as concrete, metal decking, wood panels, etc. Slabs can be classified into different types based on their thicknesses and directions of spanning, such as one-way slabs, two-way slabs, flat slabs, etc. Trusses are linear assemblies of members that span between supports and resist axial forces. Trusses can be made of various materials, such as wood, steel, aluminum, etc. Trusses can be classified into different types based on their configurations and shapes, such as triangular trusses, parallel chord trusses, warren trusses, etc. The chapter shows how horizontal spanning elements can be combined with supports and connections to form different spanning systems, such as simple spans, continuous spans, cantilever spans, overhanging spans, etc. It also shows how spanning systems can be influenced by various factors, such as span lengths, load distributions, support conditions, connection details, etc. ## Vertical Dimensions ## Vertical Dimensions The third chapter deals with vertical dimensions and why they are important for structural design. Vertical dimensions are the heights or elevations of structural elements and spaces in a building. Vertical dimensions affect the stability, strength, and stiffness of structural elements, as well as the functional and aesthetic requirements of spaces. The chapter discusses the three basic types of vertical elements: columns, walls, and frames. Columns are linear elements that are subjected to axial compression, as shown in figure 1.2a. They are also referred to as struts or stanchions. Columns can be circular, square, or rectangular in their cross sections, and they can also be of standard sections such as steel I-beams or concrete T-beams. Columns can be classified into different types based on their slenderness ratios, which are the ratios of their lengths to their radii of gyration. Slender columns are more prone to buckling than short columns. Walls are planar elements that are subjected to axial compression and bending, as shown in figure 1.2b. They are also referred to as piers or shear walls. Walls can be solid or perforated, and they can be made of various materials such as brick, concrete, stone, wood, etc. Walls can be classified into different types based on their orientations and functions, such as load-bearing walls, non-load-bearing walls, partition walls, retaining walls, etc. Frames are volumetric assemblies of members that are subjected to axial forces and bending moments, as shown in figure 1.2c. They are also referred to as rigid frames or moment frames. Frames can be made of various materials such as steel, concrete, wood, etc. Frames can be classified into different types based on their configurations and shapes, such as portal frames, gable frames, flat frames, etc. The chapter shows how vertical elements can be used to support horizontal spans and resist lateral forces in various types of buildings, such as residential buildings, commercial buildings, industrial buildings, etc. It also shows how vertical dimensions can be influenced by various factors, such as site conditions, functional requirements, aesthetic preferences, cultural values, etc. ## Lateral Stability The fourth chapter covers lateral stability and why it is important for structural design. Lateral stability is the ability of a structure to resist lateral forces that tend to cause displacement or deformation of the structure in a horizontal direction. Lateral forces can be caused by natural phenomena such as wind, earthquake, and soil pressure, or by human activities such as traffic, machinery, and explosions. The chapter discusses the three basic types of lateral-force-resisting systems: shear walls, braced frames, and moment-resisting frames. Shear walls are planar elements that resist lateral forces by shear deformation, as shown in figure 1.3a. They are usually located at the perimeter or core of a building, and they can be made of various materials such as concrete, masonry, wood, etc. Shear walls can be classified into different types based on their shapes and openings, such as rectangular shear walls, flanged shear walls, coupled shear walls, etc. Braced frames are linear assemblies of members that resist lateral forces by axial deformation, as shown in figure 1.3b. They are usually located at the interior or exterior of a building, and they can be made of various materials such as steel, wood, aluminum, etc. Braced frames can be classified into different types based on their configurations and bracing patterns, such as concentric braced frames, eccentric braced frames, K-braced frames, X-braced frames, etc. Moment-resisting frames are volumetric assemblies of members that resist lateral forces by bending deformation, as shown in figure 1.3c. They are usually located at the interior or exterior of a building, and they can be made of various materials such as steel, concrete, wood, etc. Moment-resisting frames can be classified into different types based on their connections and joint details, such as simple connections, semi-rigid connections, rigid connections, etc. The chapter shows how lateral-force-resisting systems can be used to provide lateral stability for various types of buildings, such as low-rise buildings, mid-rise buildings, high-rise buildings, etc. It also shows how lateral stability can be influenced by various factors, such as lateral load magnitudes, lateral load distributions, structural stiffness, structural ductility, structural redundancy, etc. ## Long-Span Structures The fifth chapter focuses on long-span structures and why they are important for structural design. Long-span structures are structures that have large horizontal spans between supports, usually exceeding 20 meters. Long-span structures are often used for buildings that require large open spaces, such as auditoriums, stadiums, airports, bridges, etc. The chapter discusses the main challenges and opportunities of designing long-span structures. The main challenges are: - To provide adequate strength and stiffness to resist large gravity and lateral loads - To minimize the self-weight and material consumption of the structure - To control the deflection and vibration of the structure - To coordinate the structural system with other building systems such as enclosure, mechanical, electrical, etc. The main opportunities are: - To create expressive and iconic forms and shapes - To enhance the spatial quality and functionality of the spaces - To integrate the structure with the architecture and the environment - To explore innovative materials and technologies The chapter discusses some examples of long-span structures, such as arches, domes, vaults, cables, membranes, etc. Arches are curved elements that span between supports and resist compression, as shown in figure 1.4a. They can be made of various materials such as stone, concrete, steel, wood, etc. Arches can be classified into different types based on their shapes and supports, such as circular arches, parabolic arches, catenary arches, hinged arches, fixed arches, etc. Domes are curved elements that span over a circular or polygonal base and resist compression, as shown in figure 1.4b. They can be made of various materials such as concrete, masonry, steel, wood, etc. Domes can be classified into different types based on their shapes and supports, such as hemispherical domes, elliptical domes, conical domes, geodesic domes, etc. Vaults are curved elements that span over a rectangular or polygonal base and resist compression, as shown in figure 1.4c. They can be made of various materials such as concrete, masonry, steel, wood, etc. Vaults can be classified into different types based on their shapes and supports, such as barrel vaults, groin vaults, ribbed vaults, fan vaults, etc. Cables are flexible elements that span between supports and resist tension, as shown in figure 1.4d. They can be made of various materials such as steel, synthetic fibers, etc. Cables can be classified into different types based on their shapes and supports, such as straight cables, parabolic cables, catenary cables, suspension cables, etc. Membranes are flexible elements that span over a base and resist tension, as shown in figure 1.4e. They can be made of various materials such as fabric, plastic, rubber, etc. Membranes can be classified into different types based on their shapes and supports, such as flat membranes, curved membranes, pneumatic membranes, tensile membranes, etc. The chapter shows how long-span structures can be used to create different spatial compositions and effects, such as span, height, light, color, texture, etc. It also shows how long-span structures can be influenced by various factors, such as structural form, structural behavior, structural efficiency, structural aesthetics, etc. ## High-Rise Structures The sixth chapter deals with high-rise structures and why they are important for structural design. High-rise structures are structures that have large vertical dimensions, usually exceeding 50 meters or 15 stories. High-rise structures are often used for buildings that require high density, visibility, or prestige, such as offices, hotels, apartments, etc. The chapter discusses the main challenges and opportunities of designing high-rise structures. The main challenges are: - To provide adequate strength and stiffness to resist large gravity and lateral loads - To minimize the self-weight and material consumption of the structure - To control the deflection and vibration of the structure - To coordinate the structural system with other building systems such as enclosure, mechanical, electrical, etc. - To ensure the safety and comfort of the occupants The main opportunities are: - To create expressive and iconic forms and shapes - To enhance the spatial quality and functionality of the spaces - To integrate the structure with the architecture and the environment - To explore innovative materials and technologies The chapter discusses some examples of high-rise structures, such as rigid frames, tube systems, outrigger systems, core systems, etc. Rigid frames are volumetric assemblies of members that resist lateral forces by bending deformation, as shown in figure 1.5a. They can be made of various materials such as steel, concrete, wood, etc. Rigid frames can be classified into different types based on their configurations and shapes, such as portal frames, gable frames, flat frames, etc. lateral forces by shear deformation, as shown in figure 1.5b. They can be made of various materials such as steel, concrete, etc. Tube systems can be classified into different types based on their shapes and supports, such as rectangular tubes, circular tubes, triangular tubes, etc. Outrigger systems are hybrid assemblies of members that resist lateral forces by connecting the core structure to the perimeter columns, as shown in figure 1.5c. They can be made of various materials such as steel, concrete, etc. Outrigger systems can be classified into different types based on their locations and configurations, such as single outriggers, double outriggers, belt trusses, etc. Core systems are planar or volumetric assemblies of members that resist lateral forces by forming a stiff core structure at the center of the building, as shown in figure 1.5d. They can be made of various materials such as concrete, steel, etc. Core systems can be classified into different types based on their shapes and openings, such as solid
