| dc.description.abstract | Over the last decades, increasing computational power is allowing engineers to do more advanced earthquake assessments on structures. The actual performance during seismic loading of buildings can be assessed using complicated material models, and analyses methods. Throughout this thesis, advanced non-linear analyses, both dynamic and static, are described, conducted and discussed. The structure that is used for the analyses is a reinforced concrete frame building, designed according to EN 1998-1 for ductility class medium. Analyses are primarily conducted using the open source finite element package OpenSees, but for some analyses the commercial FEA program Seismostruct is also used. A parameter study is done on the structure for comparison. Though expected, the analyses revealed that the design code is highly conservative, even when the structure remains in the elastic range. The sample structure is able to withstand major inelastic deformations. Assessing the structural behavior with performance-based earthquake engineering methods, the real collapse capacity are obtained and the safety assessed using probabilistic theory. | |
