On a numerical model for static and dynamic analysis of in-plane masonry infilled steel frames

A numerical model is presented for both static and dynamic analysis of planar masonry-infilled steel frames, which are loaded only in their plane. The model can simulate all main nonlinear effects of the frame-infill-foundation-soil system. With this model, bare steel and concrete frame structures, masonry structures, as well as masonry-infilled steel and concrete frame structures can be analysed. Verification of this model was performed on two experimental tests. In example 1 a masonry-infilled steel frame under static cyclic load and in example 2 a masonry-infilled steel frame under dynamic load were analysed. The obtained numerical results agree well with experimental results.
