摘要

钢筋混凝土桥柱中,复合箍筋配筋方式非常复杂,施工难度大,用钢量多,且不易保证施工质量。本文针对该配筋方式存在的问题,提出了一种新型的配筋方式,S-Clip筋。为了验证这种新型配筋方式的有效性,按照纵筋配筋率的不同,制作了两组大型桥墩柱的模型。通过两组模型的低周反复荷载试验,研究了分别采用普通复合箍筋和新型S-Clip筋的桥墩柱的抗震性能。试验结果表明,新型配筋方式能够充分发挥材料的力学性能,与原配筋方式具有相同的承载能力,而且在延性方面略有提高。在工程应用中,采用S-Clip筋提高了工程质量,加快了施工速度,节约钢材,具有广泛的应用前景。该应用技术的研究,对工程结构理论和应用技术的发展有着重要的作用。

Abstract

In R.C. bridge pier, reinforcement arrangements of combined stirrups are complicated, which are difficult to construct, demand large quantity of rolled steel and hard to assure the quality of construction. According to these problems, a new type of reinforcement arrangement is proposed in this paper, called S-Clip. In order to validate the effect of this reinforcement, two groups of big sized piers were made, which are different from longitudinal reinforcement ratio. By the low cyclic reversed loading test, the seismic behavior is studied on the each bridge pier which uses conventional combined stirrups and S-Clip stirrups separately. The results indicate that the piers using new type reinforcement are not only take full advantage of material capability and have the same carrying capacity as the conventional one, but also have improved ductility. The application of this new type of reinforcement is in favor of improvement engineering quality. It speeds up the construction progress and economizes rolled steel. Therefore, the application of this technique has extensive prospect. It is very important for both the theory of structure and its development.
