Comparison of experimental results and numerical modelling of unreinforced load-bearing masonry structures subjected to earthquake loading

摘要

This paper presents a comparison of experimental tests results on unreinforcedload-bearing masonry structures subjected to earthquake loading with numerical predictions.First, simple walls are submitted to cyclic and shaking table tests. Some of them includesoundproofing devices in order to investigate their influence on the general behaviour in staticand dynamic conditions. Additional walls with an opening and T-shaped walls are then testedunder cyclic loading. The study is focused on the frame effect, the contribution of theperpendicular wall to the global strength and the efficiency of the connection. These aspectsare also studied through shaking table tests on two masonry frames with T- or L-shaped piers.The main information is expressed in terms of force-displacement curves, mechanicalproperties and energy dissipation for the cyclic tests. The shaking table tests provide resultsin terms of dynamic and mechanical properties. Comparison of the results with numericalpredictions is finally performed thanks to the software TREMURI.
