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…
Conducting modal analysis in a proper way for structures offers numerous benefits
Conducting modal analysis in a proper way for structures offers numerous benefits, which can significantly impact design, performance, and safety. Here are some key advantages : 1.Accurate Design Validation: Proper modal analysis helps validate and refine the design of structures, ensuring that they meet their intended functional requirements and safety…
Is there any limitation to the use of Modal Response Spectrum Analysis (MRSA) for seismic design and assessment of structures?
According to most seismic design and assessment standards, it seems that regardless of any plan or vertical stiffness irregularities, a linear elastic MRSA is allowed to be used as the primary analysis approach for all structures. The codes are not clear on the appropriate analysis method for cases that require…
Another post on P-delta effect
Let’s talk about P-delta effect today. This prevalent in tall buildings, tall bridge piers😁. In simple words, a deflection Delta occurs as shown in figure due to geometry configuration, this extra Delta combined with the axial load causes secondary moments in addition to primary loads, which is equal to P…
