A framework allow for both flexural and shear response analysis using a new segmental approach is developed in this proposal. A blast test program is designed to validate the framework for reinforced concrete members. The validated framework is then used to derive normalised pressure impulse programs for reinforced members in unconfined and confined spaces. This project will provide design engineers guidelines for reliably and quickly assessing the effect of different kinds of blast loads on different types and properties and geometries of reinforced concrete structural members, saving computation time and efforts while providing increased realism and accuracy.

在这一建议中，提出了一种新的分段方法，可以同时进行弯曲和剪切响应分析。设计了一个爆破试验程序来验证钢筋混凝土构件的框架。经过验证的框架随后被用于推导无限制空间和受限空间中的加固构件的归一化压力脉冲程序。该项目将为设计工程师提供可靠和快速地评估不同类型、不同性质和不同几何形状的钢筋混凝土结构构件的爆炸荷载影响的指导方针，从而节省计算时间和精力，同时提高真实性和准确性。
