Rectangular Continuous Transverse Reinforcement (RCTR), as a replacement for conventional ties, is a relatively new form of reinforcement that can accelerate and facilitate the construction of reinforcement for RC members. In this study, the compressive behavior of concrete members with this kind of reinforcement is experimentally and theoretically investigated. Twenty-eight RC short column specimens with multiple arrangements for bar size and spacing of transverse reinforcement; including RCTR and conventional ties are examined under monotonic and half-cyclic loadings. The results imply that RCTR is a valid substitute for traditional ties and to a certain extent can improve the compressive strength of RC members. Based on Elasto-Plastic and Fracture (EPF) concrete model, a theoretical method is proposed in order to predict the behavior of such members, which conforms well with the experimental results. Furthermore, the validity of existing design provisions in the compressive design of these members is investigated.

矩形连续横向钢筋钢筋混凝土构件的抗压性能

矩形连续横向钢筋（RCTR）作为传统枕木的替代品，是一种相对较新的钢筋形式，可以加速和促进钢筋混凝土构件的钢筋施工。在这项研究中，对这种钢筋混凝土构件的抗压性能进行了实验和理论研究。28个钢筋尺寸和横向钢筋间距多种排列的RC短柱试件；包括 RCTR 和常规关系在单调和半循环载荷下进行检查。结果表明，RCTR是传统拉杆的有效替代品，在一定程度上可以提高钢筋混凝土构件的抗压强度。基于弹塑性和断裂（EPF）混凝土模型，为了预测这些构件的行为，提出了一种理论方法，该方法与实验结果很好地吻合。此外，对这些构件的受压设计中现有设计规定的有效性进行了调查。
