Devastating earthquakes demonstrated that column plastic hinges were more prominent than beam hinges, resulting in global structural damage and a high risk of life-threatening injury. All structural components transfer their forces through the column, which then distributes them to the foundation and soil, so if the column fails, the entire structure collapses in seconds. By making columns more moment resistant than beams, the plastic hinges shift to the beam and prevent global damage. In this case, only the beam will show flexure as a sign of beam damage, and people will have enough time to evacuate the area during the earthquake, with beam failure limited to a specific storey. This is the concept of a strong column and a weak beam.
In this dissertation, a G+14 storey Special Moment Resisting Frame (SMRF) building is considered for the strong column weak beam concept for zone-IV, located in medium soil, and moment capacities are checked in accordance with IS 13920:2016. Response Spectrum Analysis (RSA) is performed with IS 1893:2016 code provisions for Dynamic Analysis of Structure, and Time History Analysis (THA) is performed with Bhuj/Kachchh Aftershock data for Dynamic Analysis of Structure. ETABS 2018 also performs Nonlinear Static Analysis (i.e., Pushover Analysis) to check the performance of plastic hinges of column and beam. The hinges are checked and verified in accordance with the acceptance criteria, and the structure's Performance Point has been determined using ATC-40 and FEMA 440 EL guidelines, while the structure's Target displacement has been determined using ASCE 41-13 guidelines with a defined response spectrum. The structural behaviour of the structure has been examined using parameters such as Storey Displacement, Storey Drift, Storey Shear, Mode Periods, Performance Point, and Target Displacement.
