Improved analysis and design of structures to resist blast and impact

该项目旨在开发一种改进的单自由度（SDOF）模型，该模型可以方便工程师在设计分析中使用，并在分析受爆炸和冲击载荷的结构时产生准确的结构响应预测。目前的实践是使用SDOF模型来分析受爆炸和冲击载荷的结构，然而许多实验测试和高保真度的数值模拟表明，SDOF分析并不总是导致准确的结构响应预测。该项目将开发一种改进的SDOF模型，该模型可以很容易地用于工程师的设计分析，并产生准确的结构响应预测。这将带来更经济的设计和更坚固的结构，以抵抗爆炸和冲击载荷。

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.
