Structural Analysis AND Design Computation

This document summarizes the structural analysis and design computation for proposed alterations to a one-storey residential building. It outlines the design methodology, loads, criteria, and parameters to be used, including dead loads, live loads, seismic and wind design considerations. The structural model and analysis results will be input and output from STAAD, with manual computations also to be performed.
