Soil-Structure Interaction of Tall Buildings Comprising Shear Walls with Openings Under Seismic Loads

As a result of population density in Egypt emerged the importance of the use of tall buildings. Tall buildings increase the displacement of top floors due to lateral loads effect and increase the settlement due to vertical loads. A numerical analysis is carried out to analyse buildings with shear walls that have regular and staggered openings and resting on piles raft with different pile configurations under seismic action. The behaviour of soil-structure interaction, with weak soil profile, on superstructure of 20, 25, and 30 storeys and rested on a pile raft was investigated and was found to have a significant effect on the buildings. It was found that the openings in the shear walls have a significant effect on the values of the settlement. Also, the staggered openings are preferable more than the regular openings and the effect of pile length in clay soil is greater than the pile diameter.
