Abstract

This paper presents the impact of hollow sphere on biaxial slab. To derivate the impact of hollow sphere on biaxial hollow slab, numerical simulations using nonlinear Finite Element Methods are ongoing by the nonlinear finite element program LUSAS. Recently, various types of slab systems which can reduce self-weight of slabs are studed as the height and width of building structures rapidly increase. A biaxial hollow slab systee is widely known as one of the effective slab system which can reduce self-weight of slab, A biaxial hollow slab has hollow spheres within slabs in order to reduce self-weight of slabs. Because of reducing self-weight of slabs by hollow spheres, size of vertical elements like walls and columns can be smaller and slabs span can be longer. A capacity of biaxial hollow slabs is influenced by the shape and volume of hollow spheres. Therefore, In this study, several biaxial hollow slabs which has different shapes of hollow spheres are analyzed by using the finite element method program in order to derive the impact of hollow sphere on biaxial slab.
