Performance of Drilled Shaft under Combination of Complicated Loads under Hurricane Event

Corresponding data set for Tran-SET Project No. 18GTTSA02. Abstract of the final report is stated below for reference: "This project includes experimental and numerical studies to investigate and assess the impact of vertical loads on a laterally loaded drilled shaft under various conditions. The experimental study includes lab testing and lab-scale load test to examine a drilled shaft subjected to vertical and lateral loads at a reduced scale. With the data obtained from the lab-scale testing, a numerical model was calibrated, which was used to perform a parametric study to scrutinize the effect of many possible factors such as soil stiffness, soil friction angle, and drilled shaft geometry. With all the factors considered in this study, the vertical load does not show significant impact on the lateral deflection of a drilled shaft unless the lateral force is very high and induces a very large deflection. Based on the outcome of this study, it can be concluded that interaction between vertical and lateral loads might be insignificant when the lateral deflection is no greater than 25 mm (i.e., one inch)."对应Tran-SET项目编号18GTTSA02的数据集。以下为最终报告摘要，供参考：本项目包含试验与数值研究，旨在探究并评估不同工况下竖向荷载对受横向荷载钻孔桩（drilled shaft）的影响。试验研究部分涵盖室内试验与缩尺模型荷载试验，对按缩尺比例制作的承受竖向与横向荷载的钻孔桩开展测试。依托缩尺试验获取的数据，对数值模型进行了校准，并基于该模型开展参数化分析，以细致考察诸多潜在影响因素，包括土体刚度、土体内摩擦角以及钻孔桩几何参数。本研究综合考量各类因素后发现，除非横向荷载极高并引发大幅变形，否则竖向荷载对钻孔桩的横向位移并无显著影响。基于本研究结果可得出结论：当横向位移不超过25 mm（即1英寸）时，竖向荷载与横向荷载之间的相互作用可忽略不计。
