Concrete buildings are subjected to contraction and expansion due to the warming and cooling of our planet through the seasons. Long term effects of such seasonal temperature changes develop stresses and deformation in the building. Concrete creep and shrinkage increase the cracks widths and stresses. For elimination of this expansion joints are provided. As per IS 456:2000 the buildings exceeding 45m length are subjected to thermal stresses. An expansion joint is a gap provided in the structure to allow expansion and contraction of the building due to temperature changes. It absorbs the heat-induced by expansion and contraction of various construction materials. This study focuses on the behaviour of RCC framed long building in the presence of expansion joint under seismic and temperature loading. A four storied building of length 50 m is analysed and designed by using STAAD PRO. And compare results by using building with expansion joint and building without expansion joint.
