ABSTRACT

This research was conducted on residential buildings with discontinuous walls from the ground floor to the upper floors due to the ground floor being used as parking areas or lobbies, commonly referred to as piloti buildings. Piloti buildings are susceptible to experiencing soft stories because the ground floor is more flexible than the floors above. The presence of the wall on the upper floor designed as confined masonry could detect a soft story. Many studies have been conducted on confined masonry models, but they still need to provide conclusive results and are still quite challenging to apply to complex buildings. This study used a layered shell SAP2000 model to model confined masonry and validated it with experimental test results. The research findings indicate that considering the presence of walls can detect soft story irregularities. Soft story evaluations suggest that the columns and beams on the ground floor should be enlarged to prevent structural collapse. Pushover analysis indicates that confined masonry construction has better stiffness and strength than open frame construction but has lower ductility. Additionally, confined masonry structures are considered more affordable regarding their reinforcement and concrete requirements. These findings can be a foundation for further development in designing confined masonry constructions in Indonesia.
