Abstract

The need for speed construction increases the use of pile bent piers. The pile bent piers not only reduces the construction time, but also, reduces the construction cost. They reduce the pile cab required frameworks time and cost. However, the behavior of the pile bent pier under seismic load may cause the pile failure under maximum moment acting on the pile under the ground with 2 to 4.5 times the pile diameter. In this research, a parametric study is performed to minimize the risks of pile failure under seismic loads by increasing the pile stiffnesses in the critical location using soil grouting. Different grouting widths (0.5, 1.0, and 1.5 m) are proposed and the effect of the grouting was compared in terms of acting forces on the pile. Grouting width 0.5 m around the pile decreases the seismic moment and increases the shear. However, increasing the grouting diameter than 0.5 m increases the pile stiffness and increases the acting forces.
