A New Prefabricated Cage System in Concrete Members: Small Grant for Exploratory Research, CMS project 0355321PI: Halil Sezen, Ohio StateA new reinforcement system, Prefabricated Cage System (PCS) is proposed to perform the functions of both longitudinal and transverse reinforcement in reinforced concrete (RC) beams and columns. This proposal includes experimental and analytical research to investigate the confinement and axial-load carrying capacity of the PCS. 20 specimens will be tested to better understand the confinement and axial behavior of PCS system. The specimens including concrete-filled steel tube, RC and PCS columns will be tested, and the results will be compared. As a result, a concrete confinement model will be developed for the proposed PCS. Based on test results, effectiveness of the proposed new system will be investigated. The proposed reinforcement system will directly impact seismic design practice by eliminating some potential failure modes in RC, and by providing larger strength and displacement ductility.

混凝土构件中的新型预制笼系统：探索性研究小额资助，CMS 项目 0355321PI：俄亥俄州 Halil Sezen 提出了一种新的加固系统，预制笼系统 (PCS)，以在钢筋混凝土中执行纵向和横向钢筋的功能（ RC）梁和柱。 该提案包括实验和分析研究，以研究 PCS 的约束和轴向承载能力。将测试 20 个样本，以更好地了解 PCS 系统的约束和轴向行为。对钢管混凝土柱、钢筋混凝土柱和PCS柱等试件进行测试，并对结果进行比较。因此，将为所提出的 PCS 开发一个具体的约束模型。根据测试结果，将调查所提出的新系统的有效性。所提出的加固系统将通过消除钢筋混凝土中的一些潜在失效模式并提供更大的强度和位移延性来直接影响抗震设计实践。
