Abstract: Based on the numerical simulation of the basic behavior of multi-ribbed composite wall under low frequency cyclic load, the skeleton curve is consistent with the experimental results. Also, the factors such as axial compression ratio, the intensity of filling blocks and the shear span ratio which may influence the shape of the skeleton curves are analyzed. The results shows that the yield load of multi-ribbed composite wall as well as the limit load are positively related to the block strength, while are negatively related to shear span ratio. Besides, by the method of finite element model, 9 groups of skeleton curve data of multi-ribbed composite wall in different axial compression ratio, shear span ratio and the intensity of filling blocks were simulated. On the basis of multiple linear regression analysis of the numerical results, the equations for calculating the feature points in the skeleton curve are given.
