Macroelement modeling of unreinforced and reinforced experimental tests on masonry walls

This paper deals with the numerical simulation of the results of an experimental campaign performed at the ENEA Casaccia Research Center on an unreinforced and a reinforced ma- sonry wall with an innovative strengthening technique derived from the CAM solution. The nonlinear constitutive response of masonry is accounted for in the numerical model by nonlin- ear lumped hinges with a modified Bouc-Wen constitutive law, introduced in a macroelement in the framework of the equivalent frame model. The comparison between numerical and ex- perimental outcomes appears to be satisfactory, proving the accuracy of the simplified model.
