ABSTRACT
This chapter focuses on the sensitivity analyses as tool to identify the main parameters that affect the seismic response of one type of the old mixed masonry-reinforced concrete buildings in Lisbon. Reinforced concrete (RC) lintel beams are placed on top of the windows on the front façade wall. Furthermore, the floor of the building consists of two different structural types: timber floors, at the front of the building, whereas in the salient shape of the building, supported by the reinforced concrete frame, concrete slabs were placed. Nonlinear static analyses allow assessing the seismic global behavior of masonry and mixed masonry-RC buildings governed by the in-plane response of walls. In order to perform the nonlinear static analyses of the selected mixed masonry-RC building, a three dimensional model was defined by the software Tremuri, which allows the execution of nonlinear static analyses of entire masonry buildings by means of an equivalent frame idealization of the structure.
