Abstract

One of the tests in the ESECMaSE project is the large scale earthquake test on a building. The finite element model that is discussed in this thesis is based on this pseudo-dynamic test. The material model follows from a macro modelling approach and has smeared-cracks. The mode shape and eigenfrequencies are obtained through an eigenvalue analysis. The seismic load is applied in a fixed force ratio with the aid of an auxiliary frame in order to perform a displacement controlled analysis. A sensitivity study to several modelling aspects and modelling parameters was carried out to verify modelling assumptions. It is concluded that a cyclic pushover analysis approximates the results from the test the best. The crack patterns in both models are similar and the shear capacity in the weakest direction is approached up to 29%.
