Abstract
In order to study the restoring force model of multi-ribbed composite wall,Pseudo-static tests of 9 samples had been carried out under cyclic lateral loading,and the failure process and failure characteristics are summarized in details.By analysis of skeleton curve and stiffness degradation,four linear restoring force model of the multi-ribbed composite wall has been established according the rule that the curve points to the maximum value as reverse loading.The calculation of the main parameters of the skeleton curve are given by tests and theoretical analysis,and the values of the calculation are consistent of that of the tests.The restoring force model reflects the failure process of the multi-ribbed composite wall as crack-yield-failure,which provide basis for elastic-plastic time-history analysis of multi-ribbed composite wall structure.
