Unit I a) Types of steel structures, grades of structural steel, various rolled steel sections, relevant IS specifications such as IS:800-2007, IS:808-1989, IS:875 part I to III, SP: 6(1), SP: 6(6), SP 38. IS:4000-1992, codes for welded connections (mention code). Philosophy of limit state design for strength and serviceability, partial safety factor for load and resistance, various design load combinations, classification of cross section such as plastic, compact, semi-compact and slender. b) Tension member : various cross sections such as solid threaded rod, cable and angle sections. Limit strength due to yielding, rupture and block shear. Design of tension member: using single and double angle sections, connections of member with gusset plate by bolts and welds. (Chapters - 1, 2) Unit II a) Buckling classification as per geometry of cross section, buckling curves, design of struts in trusses using single and double angle section, connections of members with gusset plate by bolts and welds. b) Design of axially loaded column using rolled steel section. Design of built-up column, lacing and battening, connection of lacing/battening with main components by bolts and welds. (Chapter - 3) Unit III a) Design of eccentrically loaded column providing uniaxial and biaxial bending (check for section strength only). b) Design of column bases : Design of slab base, gusseted base, and moment resistant base. (axial load and uni-axial bending) (Chapters - 4, 5) Unit IV a) Design of laterally supported beams using single rolled steel section with and without flange plate, curtailment of flange plates, strength in flexure, low and high shear, check for web buckling, web crippling and deflection. b) Design of laterally unsupported beams using single rolled steel section with and without flange plate, curtailment of flange plates, strength in flexure and shear, check for deflection.(Chapter - 6) Unit V a) Secondary and main beam arrangement for floor of a building, design of beam to beam and beam to column connections using bolt / weld. b) Design of welded plate girder: design of cross section, curtailment of flange plates, stiffeners and connections.(Chapter - 7) Unit VI a) Design of gantry girder : Selection of gantry girder, design of cross section, check for moment capacity, buckling resistance, bi-axial bending, deflection at working load and fatigue strength. b) Roof truss : assessment of dead load, live load and wind load, design of purlin, design of members of a truss, detailing of typical joints and supports.
