Advanced design of steel structures

Overview

About the course:The proposed course is designed to enhance and strengthen the knowledge on detailed design methods for steel structures, in compliance with Indian and International codes. Detailed numerical modelling for preliminary analysis and design of steel members under special loads like fire, impact loads, ice loads and blast loads will be discussed. This course also covers topics on stability analysis of steel structures and supported by Matlab programsPRE-REQUISITES: 4th year Civil engg, PG students of 1st SemINTENDED AUDIENCE: UG students of Civil Engg, PG students of structural engineering, PG students of Mech, Aerospace and Appl Mech, Faculty of civil engineering, PG students of Ocean engg and Naval arch, MS and PhD scholars of the above disciplineINDUSTRY SUPPORT:L&T, ONGC, DGNP, and all major consulting organizations in the country

Plastic behaviour of structures- shape factor- Moment curvature relationships- upper and lower bound theorems-estimate of collapse loads- plastic design 3. Stability analysis of beam-column under axial tension and compression- Beam-column with elastic support- stability analysis of frames using stiffness approach- Stability functions- Matlab programs 4. Unsymmetric bending- curved beams with small and large initial curvature- Crane hooks- Matlab programs 5. Column design phenomenon- lateral buckling- torsional buckling- stiffeners- Beam-column design- Open sections- lateral and torsional buckling of open sections- Examples from different codes of practice (Euro Code, Australian code and Indian code) 6. Blast loads - impact loads- ice-infested loads on structures- fire loads- fire-resistant design 7.
