Comparative Study of Design of a Multi Storey Residential Building by Manual and STAAD.Pro Software Analysis Case of G+3

The main objective of this project is to analyze and design a multi-storey building [G +3 (3-dimensional frame)] using STAAD Pro. The design involves load calculations manually and analysis of the whole structure by STAAD-Pro. The design method used in STAAD-Pro analysis is Limit State Design conforming to Indian Standard Code of Practice. STAAD-Pro is the professional's choice. Initially, we started with the analysis of simple 2-dimensional frames and manually checked the accuracy of the software with our results. The results proved to be very accurate. We analyzed and designed a G + 3-storey building (2-D Frame) initially for all possible load combinations [dead and live loads]. STAAD-Pro has a very interactive user interface, which allows the users to draw the frame and input the load values and dimensions. Then according to the specified criteria assigned, it analyses the structure and designs the members with reinforcement details for RCC frames. We continued with our work with some more multi-storey 2-D and 3-D frames under various load combinations. Our final work was the proper analysis and design of a G + 3-D RCC frame under various load combinations. The materials were specified and cross-sections of the beam and column members were assigned. The supports at the base of the structure were also specified as fixed. The codes of practice to be followed were also specified for design purpose with other important details. Then STAAD-Pro was used to analyze the structure and design the members. The comparison will be made on the shear, bending moments, steel areas.
