To foster informed intuition for structures, this book has many illustrations visualizing structural behavior and to complement and clarify mathematical concepts. While the book is primarily targeted for students of architecture, it also serves as reference book for students of civil engineering, and professional architects, engineers, and contractors. The book is organized in six parts. Part I starts with an introduction of key developments in the historic evolution of structures and proceeds to introduce loads on buildings and basic systems to resist them. Part II introduces fundamentals: statics and strength of material, as well as analysis and design of basic elements, such as beams and columns. Part III introduces design methods: ASD and LRFD; design of masonry (ASD) and concrete (strength method); design for wind and seismic forces; as well as conceptual design, explored on case studies. Part IV introduces structure systems for horizontal spans, categorized by bending, axial, form, and tensile resistance. All systems are introduced with conceptual diagrams, describing their structural behavior and alternate options. Case studies describe their use in real projects. Part V introduces vertical structures in similar fashion. Part VI introduces material properties and details for wood, steel, masonry, concrete, and membrane structures. Appendices include math derivation, graphs and tables. Text srd graphics зге correlated on the same page for easy reeding end comprehension. Prerequisites for the book are algebra, trigonometry, and Newtonian physics. The book can be used in courses of s’ai:cs -and strength of material, structure systems and structural materials. Math derivations visualized help understanding and to introduce concepts also to readers with more artistic or visual modes of learning. The book includes many graphs to streamline complex tasks.
