The titled question on pattern Live load is a structural doubt asked by a structural engineer on LinkedIn
The doubt is based on IS 456 code provision. I thought of asking it here so that all civil engineering job aspirants will be benefited.
The question was ''Today while designing one-way slab, I came across this clause
I couldn't figure it out. Can you please let me know what does this clause meant?''
The fact is that the structural engineer who asked this load calculation related question is technically sound and actively discusses technical aspects. This underlines the importance of experience and learning by asking questions. He is surely in the right path.
In this world where most structural engineers focus just on modelling in ETABS and all results interpreted from etabs. When it is absolutely fine and a requirement to use software for analysis and design, please note that such load calculations, pattern loading and various live load reduction and seismic mass calculations are all input in etabs.
It is required that young structural engineers and civil engineers know about these code provisions
Please discuss this in the Forum, and I will put up a video soon on this topic of Live Load Pattern Loading.
I have written a Blog and also a Video on this topic of pattern load.Click here to see the Vlog
sir, This clause is used to find the positive and negative bending moment by using substitute frame method. By different combinations we get max moment . The logic behind this clause is consider some material or person is walking in adjacent span or else in all span it describes how the structural element will behave, it ultimately talks about the moment and shear force
