拟议的研究项目旨在提供急需的性能数据的钢筋砌体（RM）建筑构件爆炸。该研究分为三个互补的重点领域，涵盖了广泛的实验和分析工作。重点领域I旨在提供对RM填充墙和剪力墙在准静态面外荷载下的行为的基本理解。重点领域II的目标是提供RM墙的性能在现实的爆炸载荷条件下，不同的压力和脉冲组合，以模拟真实的爆炸场景的实验证据。重点领域I和II都包括大量的分析工作，以模拟墙的行为。分析工作包括开发壁面阻力函数、设计图表以及单自由度和多自由度模型。重点领域III的研究工作补充了重点领域I和II的工作，通过使用数值方法来模拟爆炸波与墙的相互作用，并分析重点领域II中测试的墙的动态响应。此外，使用实验校准的数值模型，将产生一个广泛的墙壁爆炸性能数据库，以涵盖重点领域三测试之外的不同场景。最后，实验、分析和数值模型结果将被整合到一个性能评估工具中，这将有助于在不同的意外和故意爆炸场景下快速筛选和性能评估RM组件。四个硕士，四个本科生暑期研究助理，和两个技术人员在不同领域的砌体墙的行为，对爆炸荷载的反应，结构动力学，硬化策略，实验测试，先进的分析和numericalmodeling技术。因此，拟议的研究将有助于迫切需要加拿大的专门知识在爆炸载荷下的结构性能评估领域。

The proposed research project aims at providing critically needed performance data of Reinforced Masonry(RM) building components under blast. The research is structured into three complementing Focus Areas thatcover a wide range of experimental and analytical work. Focus Area I aims at providing basic understanding ofthe behaviour of RM infill and shear walls under quasi-static out-of-plane loading. The goal of Focus Area II isto provide experimental evidence of the performance of RM walls under realistic blast loading conditions withdifferent pressure and impulse combinations to simulate real explosion scenarios. Both Focus Areas I and IIinclude a significant amount of analytical work to simulate wall behaviour. The analytical work involvesdeveloping wall resistance functions, design charts, and single- and multi-degree-of-freedom models. Theresearch work in Focus Area III complements the work in Focus Areas I and II through use of numericalmethods to model the blast wave-wall interaction and analyse the dynamic response of the walls tested in FocusArea II. In addition, using the experimentally calibrated numerical models, an extensive wall blast performancedatabase will be generated to cover different scenarios others than those tested in Focus Area III. Finally, theexperimental, analytical, and numerical model results will be integrated into a performance assessment tool thatwill facilitate rapid screening and performance evaluation of RM components under different accidental anddeliberate explosion scenarios.The research will provide unique training to four Ph.D., four Masters, four undergraduate summer researchassistants, and two technicians in different areas related to masonry wall behaviour, response to blast loads,structural dynamics, hardening strategies, experimental testing, and advanced analytical and numericalmodeling techniques. As such, the proposed research will contribute to urgently needed Canadian expertise inthe area of structural performance evaluation under blast loads.
