砌体墙抗冲击落锤试验方法研究与应用

摘要

阐述了砌体墙抗爆炸冲击试验研究现状,针对现有砌体墙试验方法的优缺点,结合湖南大学结构实验室已有的实验条件,提出了利用落锤试验机进行砌体墙抗冲击试验研究的方法；介绍了落锤试验机的试验原理、试验装置和测试系统,砌体墙抗冲击试验加载装置和试验方案.应用所提出的试验方法进行了碳纤维布加固砌体墙和未加固砌体墙的落锤冲击试验,通过试验现象和试验结果的分析,探讨了使用落锤试验机进行墙体抗冲击试验的可行性.%Experimental study of blast-resistant masonry walls is reviewed in this paper. Considering the advantages and disadvantages of existing testing methods, an impact testing method for masonry walls is proposed by using the drop hammer machine based on the current condition of the laboratory of Hunan University. The basic theory, equipment, and testing system of the drop hammer machine are introduced, as well as the impact testing program for masonry walls. Impact tests of two masonry walls using drop hammer machine were conducted, with one strengthened by CFRP sheets. Based on the discussion of testing phenomena and results, the feasibility of u-sing the drop hammer machine to investigate the behaviour of impact-resistant walls was verified.
