The Effect of the Addition of a Shear Wall in Dealing with Earthquake Loads on the Construction Structure of UIN Maulana Malik Ibrahim Campus 3 Phase 2 Engineering Faculty Building 2 Malang

The Phase 2 Engineering Faculty Building 2 at Campus 3 of UIN Maulana Malik Ibrahim Malang is a four-storey structure with an elevation of +17.75 meters, designed without the use of shear walls. This study aims to evaluate the structural performance of the existing building without shear walls and to examine the impact of adding two different shear wall models placed along the longitudinal and transverse directions. The research was conducted through experimental observation using a quantitative approach. The shear wall modelling was carried out in 3D using the Robot Structural Analysis Professional (RSAP) software. Based on the modelling output, structural performance analysis was conducted in accordance with the parameters outlined in SNI 1726:2019 and the guidelines from the Applied Technology Council 40 (ATC-40). The structural performance level was assessed using nonlinear static pushover analysis. The results indicate that the inclusion of shear walls increases the structural performance level up to 85.1%. This suggests that the presence of shear walls significantly enhances the building’s capacity to withstand seismic loads, with an improvement in stiffness and lateral stability of 80 mm. This value was determined by comparing the deformation of the existing structure with the two modified models, showing deformation values of 78.510 mm for the existing structure, 60.56 mm for model 1, and 11.73 mm for model 2, measured at the roof level as the primary point of evaluation.
