Experimental investigation of the influence of slenderness ratio and of the in-plane/out-of-plane interaction on the out-of-plane strength of URM infill walls

The conservativeness of literature formulations in predicting the effects of IP/OOP interaction is assessed. The experimental results are collected together with those presented in literature to propose formulations for the prediction of the reduction of OOP response parameters as a function of the IP displacement demand and of the h/t ratio.
