A New Prefabricated Cage System in Concrete Members: Small Grant for Exploratory Research

一种新的混凝土构件预制保持架系统：探索性研究小额赠款，CMS项目0355321PI：Halil Sezen，俄亥俄州提出了一种新的配筋系统，预制保持架系统(PCS)，用于在钢筋混凝土(RC)梁和柱中同时执行纵向和横向钢筋的功能。该方案包括试验研究和分析研究，以研究PCS的约束和轴向承载能力。为了更好地了解PCS系统的约束和轴向性能，将对20个试件进行试验。对钢管混凝土柱、钢筋混凝土柱和PCS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开发混凝土约束模型。根据测试结果，将调查拟议的新系统的有效性。通过消除RC中一些潜在的破坏模式，并提供更大的强度和位移延性，建议的加固体系将直接影响抗震设计实践。

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.
