Blast Resistance of Concrete and Masonry Structures Retrofitted with Hybrid Composites

9729679 Saadatmanesh该项目将进行初步的分析和实验研究，以调查塑料材料加固建筑物的可行性。分析研究将集中于优化碳纤维和玻璃纤维的相对比例，以实现爆炸加载所产生的能量的最佳吸收和耗散。理论将以通用的形式发展，可适用于典型建筑的这种加固系统的设计。研究的实验部分将集中在通过高冲击载荷提供的模拟爆炸载荷下对这一概念的评估。混凝土和砖样本将被建造并用混合复合板进行加固，然后在冲击载荷下进行测试。作为对照，也将对未翻新的标本进行测试。试验结果将验证该加固系统的有效性。***

9729679 Saadatmanesh This project will conduct a preliminary analytical and experimental study to investigate the feasibility of strengthening buildings by plastic materials. The analytical study will focus on the optimization of the relative ratio of the carbon and glass fibers for the best absorption and dissipation of the energy due to a blast loading. The theory will be developed in general format that could be applicable for the design of this strengthening system for a typical building. The experimental part of the study will focus on the evaluation of this concept under simulated blast loading delivered by means of a high impact load. Concrete as well as brick speciments will be constructed and retrofitted with the hybrid composite sheet and then tested under impact loading. Control, unretrofitted specimens will also be tested. The test results will verify the effectiveness of this strengthening system. ***
