The goals of the research are to develop an innovative exterior wall system capable of providing anti-terrorism protection and energy efficiency while maintaining cost effectiveness. The research will mesh the techniques used in the precast concrete sandwich wall industry with recent developments in construction materials and reinforcement strategies to create a non-proprietary protection system that can be readily incorporated into domestic and international building construction applications. The system will be capable of resisting pressure demands generated from intentional and unintentional explosions, near contact detonations, and ballistic demands while still maintaining architectural features and thermal efficiency. To accomplish these objectives analytical parametric studies and experimental validation will be conducted through a collaborative research program at Lehigh and Auburn Universities. The parametric studies will evaluate novel materials and reinforcement strategies using both nonlinear dynamic finite element analysis methods and simplified mechanics based approaches. The experimental studies include static, blast, and ballistic evaluations and will be used to validate the models and demonstrate the capability and limitations of the system developed. The research will advance the science of insulated concrete sandwich wall design allowing economically advantageous protection measures to be integrated into the buildings we live and work in. This will directly provide a societal benefit by creating a system that will enhance our national defense. The research will expand ongoing studies on cement based insulated wall systems conducted by engineering organizations and government laboratories allowing current collaborations to be continued and strengthened. Broad dissemination of the research will be accomplished through partnership and involvement of industry representatives from the tilt-up concrete and prestressed concrete markets and participation of research groups from the U.S. Army and Air Force. The program will provide advanced training to undergraduate and graduate students and industry participants through newly developed courses. Underrepresented groups will be recruited for participation in the project.

这项研究的目标是开发一种创新的外墙系统，能够在保持成本效益的同时提供反恐保护和能源效率。这项研究将把预制混凝土夹层墙体行业中使用的技术与建筑材料和加固策略的最新发展结合起来，以创建一种可以很容易地纳入国内和国际建筑施工应用的非专有保护系统。该系统将能够抵抗有意和无意爆炸、近接触爆炸和弹道要求产生的压力要求，同时保持建筑特征和热效率。为了实现这些目标，将通过利哈伊大学和奥本大学的合作研究计划进行分析参数研究和实验验证。参数研究将使用非线性动态有限元分析方法和基于简化力学的方法来评估新材料和加固策略。实验研究包括静态、爆炸和弹道评估，将用于验证模型并展示所开发系统的能力和局限性。这项研究将推进保温混凝土夹层墙设计的科学，使经济上有利的保护措施整合到我们生活和工作的建筑中。这将通过创建一个将加强我们国防的系统来直接提供社会效益。这项研究将扩大工程组织和政府实验室正在进行的关于水泥基保温墙系统的研究，使目前的合作得以继续和加强。这项研究的广泛传播将通过来自倾斜混凝土和预应力混凝土市场的行业代表的合作和参与以及美国陆军和空军的研究小组的参与来实现。该计划将通过新开发的课程为本科生和研究生以及行业参与者提供高级培训。将招募任职人数不足的团体参加该项目。
