This project aims to develop an improved single-degree-of-freedom (SDOF) model which can be easily used in design analysis by engineers and yield accurate structural response predictions in analysis of structures subjected to blast and impact loads. Current practice uses SDOF models in analysis of structures subjected to blast and impact loads, however many experimental tests and high fidelity numerical simulations have revealed the SDOF analysis does not always lead to accurate structural response predictions. This project will develop an improved SDOF model, which can be easily used in design analysis by engineers and yield accurate structural response predictions. These will lead to more economical designs and robust structures that resist blast and impact loads.

该项目旨在开发一种改进的单自由度(SDOF)模型，该模型可以方便地用于工程师的设计分析，并在分析爆炸和冲击载荷下的结构时产生准确的结构响应预测。目前的做法是使用单自由度模型来分析结构在爆炸和冲击载荷作用下的响应，然而许多实验测试和高保真数值模拟表明，单自由度分析并不总是能够得到准确的结构响应预测。该项目将开发一种改进的单自由度模型，该模型可以方便地用于工程师的设计分析，并产生准确的结构响应预测。这些将导致更经济的设计和坚固的结构，以抵御爆炸和冲击载荷。
