Abstract

Abstract

An elastoplastic macro-model is presented for multi-ribbed compositewalls with shear deformation. The model is composed of three vertical line elements to simulate the composite slab and end columns respectively. The model is based on the finite element but with much less degrees of freedom. When the Link element in SAP 2000 is used to establish model, the element stiffness matrix of link element is deduced. A defining method is developed to determine the location of the shear spring. Combined with hysteretic axial model of reinforced concrete columns and hysteretic shear model of composite walls, the calculating formula for force-displacement relationship of plastic hinges in link element is derived. By using this model, nonlinear analysis of the wall is performed. Comparing with the experimental results, it shows that the model is characterized by clearness in principle, preferable calculating precision. It's suitable for nonlinear time-history analysis of multi-ribbed slab structure.
