Today let’s talk about how member behaviours are classified as flexural dominated and shear dominated. There is an term(beta) which is basically ratio of flexural stiffness to shear stiffness. Please refer the screenshot on the left for it. To simplify this ratio depends on poisson ratio, span/depth ratio and end…
Ductility is a structural design requirement in most design codes. In steel reinforced concrete (RC) structures, ductility is defined as the ratio of post-yield deformation to yield deformation which usually comes from steel yield. Properly reinforced and dimensioned concrete members exhibit a good ductile behavior. Ductility is the ability of…
ETABS-Non-Linear or higher will automatically create construction sequence for multistorey building without much effort. The ultimate loads are rarely more than 5% different even with transfer structures at low levels. Just export conventional dead load and sequential dead load to a spreadsheet and compare them next to each other to…
Buildings with more parking requirements tend to have multiple basements or podiums levels. Usually, these parking levels are extended beyond the tower area and into the non-tower part increasing the floor diaphragm significantly. [1] This essentially help in lateral load resisting system as it introduces an intermediate support at the…
The Most Ignored Portion in Design offices. Probably most of the design consultancies ignore modelling of infill wall, though Clause 7.9 of IS 1893 2016 explains modelling of walls as equivalent single strut. Why do we ignore it even after knowing that these inaccurate model being less stiff compared to…
