The storey-by-storey design approach currently in MASS can excessively amplify shear forces beyond expected results In cases where a bug or other issue is found in the MASS software, announcements are posted on the software’s known bugs page, as well as on this page here. It is always encouraged Read more…
MASS does not design floor slab systems but allows for them to be modeled within Multi-Storey Shear Walls for the software to design the masonry supporting and spanning between them. Slabs are basically rectangles on the cross section that appear between designed shear wall elements. It is assumed that Read more…
While not explicitly listed as a strain limit, the minimum boundary element size can have a large effect on how high maximum compressive strain can be increased. As part of the process of addressing a shear wall design with inadequate ductility, MASS will increase the maximum compressive strain, εmu Read more…
