摘要:
为解决工程实践中当混凝土结构内钢筋用量较大时钢筋间距过小的问题,提出了将纵向受力钢筋并筋布置的方法.根据31个并筋粘结锚固拉拔试件验的结果,进行了17根钢筋混凝土并筋梁的受力性能试验,较详细地讨论了并筋梁粘结锚固的特点以及影响并筋粘结锚固的主要因素,并与一般梁进行了对比.试验研究结果表明,采用并筋后钢筋和混凝土之间的粘结锚固性能有所下降,但粘结滑移特性与一般梁相近,通过适当延长锚固长度即可保证并筋梁的锚固强度和承载力,从而使并筋梁可在工程实践中应用.给出了并筋锚固长度计算的建议公式,计算结果与试验结果符合
Abstract:
In order to solve the problem that the steel bar spacing is too small when the amount of steel bars in the concrete structure is large in engineering practice, a method of arranging the longitudinal stressed steel bars and reinforcing them is proposed. According to the results of 31 reinforced bonded anchoring drawing specimens, the stress performance test of 17 reinforced concrete reinforced beams was carried out, and the characteristics of bonded anchoring of reinforced beams and the main factors affecting bonded anchoring were discussed in detail, and compared with general beams. The experimental results show that the bonding and anchoring performance between steel and concrete decreases after the use of reinforcement, but the bond-slip characteristics are similar to those of general beams, and the anchoring strength and bearing capacity of the reinforced beams can be guaranteed by extending the anchoring length appropriately, so that the reinforced beams can be applied in engineering practice. The suggested formula for calculating the anchorage length of the reinforcements is given, and the calculation results are consistent with the test results
