Shake table test of a masonry building retrofitted with shotcrete

Katrin Beyer, Kiarash Mohtasham Dolatshahi

This paper presents the results of a series of shake table tests carried out on a half-scale single-story unreinforced masonry building with asymmetric openings. First, the unretrofitted building is subjected to seven increasing steps of bidirectional seis ...

Stiffness and Strength Estimation of Damaged Unreinforced Masonry Walls Using Crack Pattern

Katrin Beyer, Kiarash Mohtasham Dolatshahi

After an earthquake, the residual stiffness and strength of structural elements are typically estimated based on a qualitative visual inspection of cracks that is prone to error. In this paper a new approach is proposed to automatically estimate the update ...

Numerical study on factors that influence the in-plane drift capacity of unreinforced masonry walls

Katrin Beyer, Kiarash Mohtasham Dolatshahi

Displacement‐based assessment procedures require as input reliable estimates of the deformation capacity of all structural elements. For unreinforced masonry (URM) walls, current design codes specify the in‐plane deformation capacity as empirical equations ...

Influence of load history on the force-displacement response of in-plane loaded unreinforced masonry walls

Katrin Beyer, Bastian Valentin Wilding, Kiarash Mohtasham Dolatshahi

Empirical drift capacity models for in-plane loaded unreinforced masonry (URM) walls are derived from results of quasi-static cyclic shear-compression tests. The experimentally determined drift capacities are, however, dependent on the applied demand, i.e. ...
