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…

Backstay Effect
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…
Most Ignored Portion in Design offices
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…
A 10 story apartment building has been analyzed and designed in ETABS and verified with manual calculations
A 10 story apartment building has been analyzed and designed in ETABS and verified with manual calculations .Stability check as per IS 1893 has been carried out including plan irregularity, torsion irregularity, mass irregularity, soft story, drift etc. and found the structure to be stable under the subjected load. In…
Some engineers in the practice are releasing the moment at end of the beam in case of not satisfying development length
Some engineers in the practice are releasing the moment at end of the beam in case of not satisfying development length ! Do you agree ? As per ACI code , for similar cases , you have to satisfy minimum development length (standard hook , mechanical anchorage , reducing bars…
