Highly sophisticated software design package such as MBS & STAAD Pro used for designing which reduces design time significantly and eliminates error. STAAD Pro be utilized for analyzing practically for the Pre-Engineered Buildings, implements the Bending Moment, Axial Forces, Shear Forces, Torsion, Beam Stresses. The typical codes and practice followed for the entire manufacturing system as follows.
Main Design Building Codes :-IS-875 (PartI) - 1987 : Code of Practice for Design Dead Loads for Building and Structures.
IS-875 (PartII) - 1987 : Code of Practice for Design Imposed Loads for Building and Structures.
IS-875 (PartIII) - 1987 : Code of Practice for Design Wind Loads for Building and Structures.
