Spectral Seismic Analysis of Reinforced Concrete Structures

In this research the seismic analysis of a multi tiered reinforced concrete RC frame in Jammu city was conducted to determine its functionality under mild tectonic forces. The research focused to investigate the structure response to seismic hazards in compliance with Indian's proposed seismic provisions. The frame was analyzed using the response spectrum method to determine seismic induced movements and stresses. The findings highlighted that the nodal displacements caused displacements exceeding 2 3 times the permissible limits. Horizontal motion substantially affected the axial compression loads of exterior columns compared to interior columns. Additionally compressive stresses in the bottom floor column were 1.5 2 times greater than tensile stresses. Shear forces in beams B505, B506 and B507 due to load combination 3 L C3 were around three times higher than those due to load combination 1 L C1 . The maximum compressive and tensile stresses in beams and columns induced by seismic excitation were substantially greater than those caused by gravity loads. Ramneek Paul Singh | Er.
