This document discusses the analysis and design of pre-engineered buildings (PEB). It covers structural analysis using static and dynamic methods in software like STAAD PRO. The structural design process involves steps like designing intermediate purlins, gable frames, vertical members, rafters, and other building components. Design calculations are shown for an intermediate purlin section and an intermediate gable frame subjected to wind loads. Further plans include site visits, manual design, and using software for design according to IS and AISC codes.
