DYNAMIC TEST OF PROPERTY OF CHEMICAL ADHESIVE ANCHORAGE BAR
-
摘要: 通过22个锚固试件(其中12个试件为采取在钢筋内开槽、贴片精确量测和由加载端、自由端滑移推算内滑移分布的方法)的单调拉拔试验和重复拟动力试验,对建筑结构胶植筋的粘结锚固性能及其与混凝土现浇锚筋的粘结锚固性能的对比进行试验研究。Abstract: Based on the test of 22 bond-slip specimens under the monotonous and repeated dynamical loads,the main factors affecting the bond-anchorage properties,the bond-anchorage mechanism,the bond stress-slip curves and the bond stress-position curves,were also given. According to the comparative tests under the monotonous and repeated dynamical loads,the degeneration performances of bond-anchorage for the specimens with chemical adhesive anchorage bars were investigated.
