Analysis of Seismic Effect on Pile Raft Foundation on a Multistorey Building Using ANSYS Software

People today want to remain in metropolitan regions in this era of development and globalisation. High rise buildings, bridges, nuclear power plants, and other tall and substantial constructions are in high demand. Large structures should be built to be able to support heavy loads with little settlement. A foundation that satisfies this condition is therefore crucial. One such foundation that can support heavy loads with little settlement is the piled raft foundation. It is widely utilised by designers for huge constructions in weak soil conditions, such as high-rise buildings, bridges, etc. When designing piled raft foundations, special care must be taken to prevent the possible collapse of tall residential or commercial buildings during an earthquake since piled raft foundations support the weight of important structures like high rise buildings. Three different earthquake load circumstances have been developed and examined for the piled raft system. A 3D model is taken into consideration for the most approximate and trustworthy outcomes while modelling and analysing piled raft foundation. A superstructure frame and a heaped raft base make up this model. The piled raft foundation is a composite building made of soil, rafts, and piles. For practical results, the stacked raft foundation is attached to the superstructure frame.
