This paper is focused 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. The main purpose of this analyses is to compare the seismic behavior of an existing building, representative of this typology, as a function of the changes of its properties with respect to the response of a reference model calibrated from available standards and experimental tests. The seismic performance is evaluated through the well-recognized N2 method and the influence of different material properties are taken into the account:Young modulus, shear modulus, shear strength and compressive strength of the masonry wall, as well as the shear modulus for timber floors. The equivalent frame model approach is used to define the 3D representation of the structure.
