Nair, Rahul V (2013) Performance Assessment of Multi-storeyed RC Special Moment Resisting Frames. MTech thesis.
Reinforced concrete special moment frames are used as part of seismic force-resisting systems in buildings that are designed to resist earthquakes. Beams, columns, and beam-column joints in moment frames are proportioned and detailed to resist flexural, axial, and shearing actions that result as a building sways through multiple displacement cycles during strong earthquake ground shaking. Special proportioning and detailing requirements result in a frame capable of resisting strong earthquake shaking without significant loss of stiffness or strength. These moment-resisting frames are called “Special Moment Resisting Frames” because of these additional requirements, which improve the seismic resistance in comparison with less stringently detailed Intermediate and Ordinary Moment Resisting Frames. The design criteria for SMRF buildings are given in IS 13920 (2002). In this study, the buildings are designed both as SMRF and OMRF, and their performance is compared. For this, the buildings are modelled and pushover analysis is performed in SAP2000. The pushover curves are plotted from the analysis results and the behaviour of buildings is studied for various support conditions and infill conditions. The behaviour parameters are also found for each building using the values obtained from pushover curve and is investigated.
