Seismic Performance of RC Frame with Different Types of Slabs Using Non-linear Time History

Abstract

The Composite slab made of galvanized steel deck and concrete has proven to be the most utilized slab in steel-framed structures. In this research, the seismic performance of a newly-introduced RC frame with a composite slab was analyzed and compared to the seismic performance of RC frames utilizing four other typical slabs. 23 separate ground motions were used with OpenSees to carry out nonlinear time history analysis that considered bar slip, shear deformation, and flexural deformation. The 3D building with composite slab achieved the lowest self-weight when compared to the buildings with other slab types. In addition, the base shear performance of 2D frames with composite slab was superior to those of the other cases. In accordance with Hazus-MH MR5 standards, the inter-story drift of composite slab frames and solid one-way slab frames demonstrated the best performance among the other cases. In the RC construction sector, however, composite slabs are a formidable rival to conventional slabs due to their lighter weight and superior seismic performance under NTHA, as well as their lower material consumption. Composite slabs, which consists of a concrete slab poured over a steel deck, have been demonstrated to enhance the seismic behavior of low-rise reinforced concrete building. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
