Analysis Behaviour of Podium-Type Buildings with Special Moment Resisting Frame (SMRF) and Dual System Using the Spectrum Response Method

Abstract

The design of the building structure has undergone considerable changes so that it needs to be considered more for the calculation of earthquakes. Earthquakes are one of the biggest challenges in the design of modern building structures, because seismic forces can cause serious damage if not properly anticipated plus Indonesia's territory is on the Indo-Australian Plate, the Eurasian Plate, and the Pacific Plate. Podium-type buildings are buildings that have problems with the transition of stiffness because there is a relatively large difference in stiffness to relatively small stiffness. One way to anticipate stiffness problems in podium-type buildings is to consider the frame system used because it greatly affects the behavior of podium-type buildings. In this study, the behavior of podium-type buildings using a Special Moment Resisting Frame System is compared with a Dual System using a Shear Wall. The two models were analyzed to see the behavior consisting of basic shear force, interfloor deviation and p-delta influence. From the research obtained, it was concluded that the SMRF building has a basic shear force of 9794.71, 138.53% greater than the Dual System of 2361.96. The maximum inter-floor SMRF inter-floor deviation is 64.405 mm and passes through the permit deviation. For the dual system, the maximum deviation of 29.145 is 54.76% smaller than the SMRF and the influence of p-delta for SMRF and the dual system are still within the safe limit.
