Effect of Horizontal Inclination of Lateral Load on Single Pile Behavior Subjected to Seismic Load

It is important to understand how each pile behaves during an earthquake to ensure building safety. Designing stronger foundations that could resist dynamic earthquake forces is made possible by investigating a response of single piles to seismic analysis. This decreases the risks associated with collapsing buildings and saves lives as well as property. An in-depth study of the single pile behavior under seismic loads helps improve earthquake-resistant infrastructure and enhances disaster resilience. The basic aim of the current study is to understand the effect of lateral load horizontal inclination angle on single pile behavior subjected to seismic load experimentally. A physical model testing was manufactured including a sophisticated shaking table to excite El Centro earthquake to single piles. The soil is sandy soil with a relative density equal to 65%. Lateral load is applied at 0° to 45° and 90° concerning earthquake direction. The results showed that increasing such an angle decreases the single pile’s response according to the load interface mechanism. In addition, increasing such angle from 0o to 45o and 90o decreased maximum lateral displacement by 58.98 and 77.58% respectively while the percentage of such decrement from 45° to 90° is 68.28%.
