Abstract:
A G+3 storey symmetrical steel model is designed. The entire structure is given partial moment releases. The study is carried out using STAAD pro. The percentage of moment release provided are 20%, 40%, 60%, 80%, 100%. The reduction in member forces and the required cross-sectional area for each section is computed and tabulated to find out the behaviour of the structure under varying moment release percentage as compared to that when no moment release is provided. This study is made with an attempt to find out the most economic percentage of moment release that can be provided to the steel structure.
