Abstract

While both American Society of Civil Engineers (ASCE) 7 and ASCE 61 require that kinematic (soil movement) loads be considered, they do not provide detailed guidance on the method(s) by which these loads on the structural system can be evaluated. This study discusses the modes of failure observed in real world kinematic movements, the analytical techniques used to evaluate pile-supported structures based on input soil movements, and appropriate performance limits for operational, life safety, spill prevention, and collapse prevention. The combination of kinematic and inertial loads, including simultaneous loading as well as post-kinematic inertial response is addressed. Acceptability of in-ground soil hinging and shearing is discussed in regards to acceptable performance levels. Significant parameters in the evaluation of kinematic loads are also addressed and recommendations are made on appropriate techniques for evaluation of kinematic loading.
