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 ! Do you agree ? As per ACI code , for similar cases , you have to satisfy minimum development length (standard hook , mechanical anchorage , reducing bars…
If you are a structural design engineer and review designs, you will probably find this comment because some engineers often forget it.
𝐋𝐨𝐜𝐚𝐥𝐢𝐭𝐢𝐞𝐬 𝐨𝐟 𝐏𝐥𝐚𝐬𝐭𝐢𝐜 𝐇𝐢𝐧𝐠𝐞𝐬 This a perfect example to summarise the location of the development of plastic hinges in beams. Plastic hinges will form when the flexural capacity envelope and the actual moment coincide at “Moment = Mc”, and at a distance “Lac” Let me know if you have any…
ETABS (O/S #52) column buckling. Columns in ETABS will show O/S #52 when Dns exceed 1.4. Most engineers will solve the problem by increasing the column size or adding beams. In the following example will show how to avoid the problem without increasing the column size. The column dimensions are…
