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0355321 PI：Halil Sezen，俄亥俄州一种新型加固系统，预制笼系统（PCS）被提议在钢筋混凝土（RC）梁和柱中执行纵向和横向加固功能。 这项建议包括实验和分析研究，调查的限制和轴向承载能力的PCS。将对20个样本进行测试，以更好地了解PCS系统的约束和轴向行为。对钢管混凝土柱、钢筋混凝土柱和预应力混凝土柱进行了试验，并对试验结果进行了比较。因此，将为拟议的PCS开发一个混凝土约束模型。基于测试结果，将研究所提出的新系统的有效性。建议的加固系统将直接影响抗震设计实践，消除一些潜在的破坏模式，在钢筋混凝土，并提供更大的强度和位移延性。
