摘要
以钢筋锚固深度(15D、20D)和后锚固混凝土强度(C20、C30)为参数进行无机材料后锚固混凝土受弯构件低周反复荷载试验,分析研究4组无机锚固料后锚固受弯构件和1组整浇受弯构件在低周反复荷载下的破坏机理、钢筋锚固性能、承载能力、抗震性能.研究结果表明,锚固深度为15D、20D的无机后锚固受弯构件在低周反复荷载下的承载力、钢筋锚固性能及抗震性能均比整浇构件差;无机后锚固受弯构件抗震设计的最小锚固深度建议取为20D,且应考虑附加锚固措施来保证其抗震性能.
The experiment of RC bending members constructed with post-embedded bars bonded with inorganic anchorage material and cast-in-place RC member under low cyclic loading is conducted for the parameters with anchorage depth and concrete strength grade. Comparing and analyzing the experimental phenomenon and data, the failure mechanism, anchorage behavior, the bearing capacity and seismic behavior of these members are studied. The results show that the bearing capacity, anchorage behavior and anti-seismic behavior of RC bending members age measures should be adopted to the corresponding RC members in anti-seismic design.
