Abstract

The increasing seismic activity observed in the last few years in the northern part of the Netherlands (Groningen region) due to geo-resources exploitation raised the need of assessing the current building stock, which is mainly made of low-rise unreinforced masonry structures.
In this thesis the performance of the equivalent frame modelling approach in predicting the nonlinear response of unreinforced masonry structure is evaluated. The model is applied in the case of typical Dutch modern terraced houses made of calcium silicate element masonry.
In order to evaluate the performances of the EF model, the quasi-static cyclic pushover tests on a masonry assembled structures is simulated. The model calibration and validation make use of the experimental results obtained during the large-scale tests on components and assembled structure performed at TU Delft in 2016/2017. A model sensitivity study is performed to investigate the effect of different modelling choices on the global structural response.
