A course covering the relationship between structural behavior, form, methods of construction, and tectonics for flexural structures, via successful case studies. History of supports and joints in architecture, three equations of equilibrium, types of stresses and internal forces in relation to deflected shape and with the help of models. Approximate analysis and design of existing trusses and simple frames paralleling discussions of tectonics of their details. Earthquake resistant architectural design in relation to the architectural requirement of change in infill walls. Slabs, structures of large non-load bearing surfaces, and suspended surfaces with the help of case studies. Logic behind portal and cantilever methods, high-rise building structures and their space characteristics.
