Abstract

A building structure is a series of construction elements that function to support and provide stability to the building. In a single building unit, walls are one of the elements that cannot be separated from the unit. Walls are usually used as partitions or room dividers as well as building enclosures. Based on several previous studies, it is explained that the presence of infill walls in a building can contribute significantly to structural stiffness in resisting existing lateral loads. This study aims to compare the behavioral analysis of structures consisting of Open Frame Structures (SRB), Partially Open Frame Structures (SRBS), and Closed Frame Structures (SRT) due to earthquake loads. In this case, for SRBS and SRT structures, walls are modeled as Strats determined based on the FEMA 356 Method and the Sukrawa and Budiwati Method. The behaviors reviewed include structural stiffness based on deformation on each floor, structural period, and base shear that occurs. As a research material, a three-story reinforced concrete building structure serving as a Flat located in West Nias Regency will be reviewed. The earthquake load analysis used is a dynamic load analysis of the response spectra for medium soil, based on the building's location. Structural analysis was conducted using a structural analysis program that uses the Finite Element Method (FEM)
