Building Structures Illustrated: Patterns, Systems, and Design
Francis D. K. Ching
Format: PDF / Kindle (mobi) / ePub
A new edition of Francis D.K. Ching's illustrated guide to structural design
Structures are an essential element of the building process, yet one of the most difficult concepts for architects to grasp. While structural engineers do the detailed consulting work for a project, architects should have enough knowledge of structural theory and analysis to design a building. Building Structures Illustrated takes a new approach to structural design, showing how structural systems of a building—such as an integrated assembly of elements with pattern, proportions, and scale—are related to the fundamental aspects of architectural design. 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 materails and structure. Illustrated throughout with Ching's signature line drawings, this new Second Edition is an ideal guide to structures for designers, builders, and students.
- Updated to include new information on building code compliance, additional learning resources, and a new glossary of terms
- Offers thorough coverage of formal and spatial composition, program fit, coordination with other building systems, code compliance, and much more
- Beautifully illustrated by the renowned Francis D.K. Ching
Building Structures Illustrated, Second Edition is the ideal resource for students and professionals who want to make informed decisions on architectural design.
criteria. One method allows the use of ratings determined by such recognized agencies as Underwriters Laboratory or Factory Mutual. The International Building Code itself contains a listing of prescriptive assemblies, which describe the protective measures that can be applied to structural members, to floor and roof construction, and to walls to achieve the necessary ratings. • Steel column protected by castin-place lightweight concrete with spirally wound wire tie reinforcement • 1 to 4 hour
load paths and helps prevent progressive collapse. BUILDING STRUCTURES / 37 STRUCTURAL PLANNING Continuity Continuity in a structure provides a direct, uninterrupted path for loads through a building’s structure, from the roof level down to the foundation. Continuous load paths help to ensure that all forces to which the structure is subjected can be delivered from the point of their application to the foundation. All elements and connections along a load path must have sufficient strength,
Square Grids A single square bay can be spanned with either a one-way or two-way system. However, when multiple square bays extend across the field of a square grid, the structural advantage of continuity in two directions suggests the use of concrete two-way spanning systems is appropriate, particularly for small to medium span ranges. It should be noted that while two-way structural action requires square or very nearly square bays, square bays do not always have to be spanned with two-way
vary while the feeder beams or joists will have constant span lengths. • See pages 274–276 for dome structures. STRUCTURAL PATTERNS / 53 IRREGULAR GRIDS Modifying Grids Square, rectangular, and tartan grids are all regular in the sense that they consist of regularly recurring elements regulated by orthogonal spatial relationships. They are capable of growth in a predictable manner, and even if one or more elements is missing, the pattern of the whole remains recognizable. Even radial grids
slabs meet. These intersections are capable of resisting cantilever bending moments in two directions. • Flat slabs and plates are both two-way systems that are capable of extending beyond the edge and corner columns in two directions. • One-way and two-way slab-and-beam systems use in-plane framing of the beams that span in the two principal directions to minimize the overall construction depth. • The extent of overhangs is generally a fraction of the bay dimension. An overhang dimension that
