摘要
在爆炸波的影响下,钢筋混凝土(RC)板(如:楼面和剪力墙等)既是建筑结构中受爆炸荷载作用的主要受力构件,又是建筑结构破坏的薄弱环节,而且,其破坏还直接导致建筑结构的整体刚度退化和动力响应升级。选择建筑结构中楼面设计常用的钢筋混凝土简支单向板为试验对象,对两个完全相同的试件分别进行独立的爆炸试验——爆炸Ⅰ和爆炸Ⅱ,分别观测钢筋混凝土板在弹性区域的动力响应(爆炸Ⅰ)和塑性区域的破坏特征(爆炸Ⅱ)。实验为后续进行的受爆炸荷载的钢筋混凝土板碳纤维(CFRP)加固试验研究提供了有效的基础数据和可靠的参照,实验观测到的现象和数据也可供同类研究参考。
Influenced by the blast waves, the reinforced concrete （RC） slabs, such as floors and shear walls, not only are the main structural components of a building under the blast loads, but also are the weakest links in the building failure, and their failure directly induces the structural stiffness degradation and the structural blast-response upgrading. In this paper, the RC simply supported one-way slabs, which are used commonly in the buildings, were selected as experimental objects. Blast test was performed on two reinforced concrete specimens with some sizes, material grades and arrangement of steel, two separate explosive（Blast Ⅰ and Blast Ⅱ） loaded on the specimens in order to investigate the dynamic response of the RC slab in the elastic range （Blast Ⅰ） and the failure characters in the plastic range（Blast Ⅱ）. The test results provides some effective data and reliable references and comparison in the development of experimental study on the RC slabs retrofitted with carbon fiber reinforced polymer （CFRP） sheets under blast loads in the future and the phenomena and data observed in the tests could also supply the references for the same researches carded out by others.
