Abstract EN
In order to reduce the costs and improve the overall performance of building systems, the static optimized design with variable rigidity of piled raft foundations has been widely used in recent years.
Variable rigidity design of piled raft foundations that support midrise buildings in high-risk seismic zones can alter the dynamic characteristics of the soil-pile-structure system during an earthquake due to soil-pile-structure interaction.
To investigate these aspects, a nuclear power plant sitting on multilayered soil is simulated numerically.
The paper describes a numerical modeling technique for the simulation of complex seismic soil-pile-structure interaction phenomena.
It was observed that the total shear force on top of the piles and the rocking of the raft are reduced after optimization, whereas the displacement of the superstructure is nearly unaffected.
The findings of this study can help engineers select a correct pile arrangement when considering the seismic performance of a building sitting on soft soil.
