ANALISIS KOMPARATIF PEMAKAIAN TWO-WAY SLAB DAN FLAT SLAB TERHADAP KINERJA SEISMIK GEDUNG “LP”

Indonesia is located in a seismically active region due to the presence of the Eurasian Plate and the Indo-Australian Plate. This means that buildings and non-building structures must be designed to withstand seismic forces. One of the critical elements in resisting earthquakes in a building is the floor slab. In addition to resisting seismic forces, the floor slab also serves as a walking and activity area for people. There are several types of floor slab construction, for example flat slab and two-way slab. When considering which type of floor slab construction to use in a building, a seismic performance analysis of the slabs is necessary to evaluate their effectiveness under gravitational loads and lateral forces. This study examines seismic performance indicators such as base shear, story shear, story displacement, and story drift that occur in each type of floor slab. The dimensions and specifications of the slabs used will be adjusted according to minimal requirements. The seismic analysis is conducted in three dimensions using response spectrum analysis. Based on the analysis results, it can be concluded that two-way slabs exhibit higher seismic resistance compared to flat slabs, as they result in greater base shear, story shear, story displacement, and story drift. Consequently, the design of buildings with two-way slabs will be safer against larger seismic loads than those with flat slabs.

Abstract

Indonesia is located in a seismically active region due to the presence of the Eurasian Plate and the Indo-Australian Plate. This means that buildings and non-building structures must be designed to withstand seismic forces. One of the critical elements in resisting earthquakes in a building is the floor slab. In addition to resisting seismic forces, the floor slab also serves as a walking and activity area for people. There are several types of floor slab construction, for example flat slab and two-way slab. When considering which type of floor slab construction to use in a building, a seismic performance analysis of the slabs is necessary to evaluate their effectiveness under gravitational loads and lateral forces. This study examines seismic performance indicators such as base shear, story shear, story displacement, and story drift that occur in each type of floor slab. The dimensions and specifications of the slabs used will be adjusted according to minimal requirements. The seismic analysis is conducted in three dimensions using response spectrum analysis. Based on the analysis results, it can be concluded that two-way slabs exhibit higher seismic resistance compared to flat slabs, as they result in greater base shear, story shear, story displacement, and story drift. Consequently, the design of buildings with two-way slabs will be safer against larger seismic loads than those with flat slabs.
