CONTRIBUTIONS OF COLUMN, BEAMS, AND SLABS STIFFNESS ON SEISMIC PERFORMANCE OF HIGH RISE BUILDINGS...

Columns, beams, and slabs had their stiffness lowered by 10% to 90% to demonstrate how much each part may contribute to the overall performance of high-rise buildings under seismic strain. The contribution of column stiffness and cross section (rectangular or square), building plane, beam stiffness, and slab stiffness on earthquake resistance was studied using SAP2000 version 14 for square and rectangular in plane 12th storeys RC structures (El-Centro). Top displacement, top acceleration, base shear force, base bending moments, and base normal force are the examined variables that illustrate how the difference in stiffness contributes to a comparable response. According to the study, column stiffness accounts for about 55% of earthquake resistance in high-rise buildings, beam stiffness for nearly 20%, and slab stiffness for nearly 10%. Rectangular column orientations account for almost 40% of earthquake resistance in buildings. Rectangular cross section columns must be orientated in such a way that they can withstand earthquake loads to the greatest extent possible. Exterior column orientations can be stiffened in the short direction to control top displacements and accelerations values in both the x and y dimensions in buildings with slander.
