Abstract
Recently, there has been an increased interest in the noise isolation capacity of floor slabs, and thus an increase of slab thickness is required. In addition, long span floor systems are frequently used for efficient space use of building structures. In order to satisfy these requirements, a biaxial hollow slab system has been developed. To verify the structural capacity of a biaxial hollow slab system, safety verification against earthquake loads is essential. Therefore, the seismic behavior of a biaxial hollow slab system has been investigated using material nonlinear time history analyses. For efficient time history analyses, the equivalent plate element model previously proposed was used and the seismic capacity of the example structure having a biaxial hollow slab system has been evaluated using the nonlinear finite element model developed by the equivalent frame method. Based on analytical results, it has been shown that the seismic capacity of a biaxial hollow slab system is not worse than that of a flat plate slab system with the same thickness.
