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.

CMS项目0355321PI：探索性研究的小型赠款：俄亥俄州的Halil Sezen，俄亥俄州Statea新增强系统（PCS）提议进行纵向和横向增强功能（RC RC和RC）。 该建议包括实验和分析研究，以研究PC的限制和轴向负载能力。 20个标本将进行测试，以更好地了解PCS系统的限制和轴向行为。将测试包括充满混凝土的钢管，RC和PCS色谱柱在内的样品，并将比较结果。结果，将为提出的PC开发一个具体的限制模型。根据测试结果，将研究拟议的新系统的有效性。拟议的增强系统将通过消除RC中的某些潜在故障模式以及提供更大的强度和位移延展性来直接影响地震设计实践。
