Assalam o alaikum,
I m attaching plan outline of a building quite irregular in plan. As generally, expansion joint is provided at 150ft spacing, in my case, After 150 ft, The building changes its geometry and direction of plan so Cant Decide whether it needs an expansion joint or not. It also have a big void which is an open yard in the middle of building. If expansion joint is needed, i have also marked a proposal line. Does it seem ok?
