Advanced Structural Design - Web course COURSE OUTLINE The fundamental design philosophies of concrete and steel structures have b e e n introduced in the basic courses for undergraduate students of civil engineering. This course "Advanced Structural Design" deals with the design aspects of a few special structures with a view to simulation of realistic behavior as closely as possible. For each type of structure, the modeling and analysis aspects will be initially discussed. The underlying design philosophies will be emphasized along with the procedure. The Indian and international design guidelines for each type of structure will be referred to along with case studies. The categories of structures which are going to be dealt with in this course are reinforced concrete frame buildings, liquid retaining structures, earth retaining structures, gantry girders, steel railway truss bridges and steel railway plate girder bridges. This advanced course material on structural design is expected to be useful to undergraduate students, postgraduate students, teachers and practitioners. Contents: Modeling of RC building frames, load calculations with detailed emphasis on seismic loading, analysis and design using computer programs. Design philosophies and procedures for liquid retaining structures, earth retaining structures, gantry girders, steel railway truss bridges and steel railway plate girder bridges. COURSE DETAIL
