Numerical Modelling of Steel Frames with Masonry Infilled with and with Rubber Bricks at the Corners (SISBRICK)

The purpose of this article is to use a numerical model to match the experimental results in case of steel frames with infilled masonry with or without rubber bricks at the corners (SISBRICK) under cyclic loading. The analysis are performed with opensees software using for preprocessing and postprocessing matlab. In this model the beam and column made of steel are modelled with displacement based elements and using section fiber models at each fiber the Giuffre Menegotto Pinto is used, to model the infill masonry with or without SISBRICK the concrete model based on Thorenfeldt curve is used to model the diagonals with high strength under compression and low under tension.
