1 Introduction The objective of this document is to present detailed design for checking adequacy of Existing steel(metallic)/Concrete(non metallic) structure. The structure is modelled on STAAD Pro Software. 2 Scope of the work The scope of work in this project is to provide the design document for structural steel and rcc portion i.e. Superstructure only. 3 Reference Codes and Standards 1 2 3 4 5 IS-800 Code of Practice for General Construction in Steel. IS875 (Part1 to 3) Code of practice for design loads (Other than Earthquake) for buildings and structures. IS 456 Code of Practice for Plain and Reinforced Concrete (Fourth Revision) Materials:1 Structural steel Plate Material 2 Rolled Section 3 Concrete 4 Reinforcement IS2062 IS 800 & SP -6 Grade-25 N/mm2 Grade Fe-500 N/mm2 Design Philosophy & Assumptions Following design philosophy & assumptions have been used for analysis & design of steel and rcc structure. 1) The structure is modeled, analyzed through STAAD.Pro software. 2) Wind load is considered for structure design. Basic wind speed considered for analysis = 47 m/s
