Design and Detailing of Transverse Reinforcements for High Strength Reinforced Concrete Columns Subjected to Seismic Loading

高强度钢筋混凝土应用的开发和研究是建筑规划和设计的重大进步，因为它的容量增加了。高强钢筋混凝土的设计现状需要深入研究，以准确预测其众多构件在地震等侧向动荷载作用下的预期性能。高强度钢筋混凝土也是一种复杂的建筑材料，因为大量的设计和施工限制会影响其质量、长期性能和最终应力值。为了更准确地模拟其结构反应，有必要建立一个基本的性能标准数据库。拟议的项目涉及设计和详细标准的发展，横向加固的高矩形柱，抗压强度超过15,000 psi。其目的是确定为抗震结构提供足够延展性的方法。研究计划包括实验研究和分析研究。至少12个大型柱试件将进行测试，并在不断增加的位移下承受轴向和重复的侧向载荷。从这些试验中，收集的数据将用于分析混凝土抗压强度、轴向载荷和横向钢筋类型对高强混凝土柱延性的影响。

The development and investigation of high strength reinforced concrete applications comprises a major advance in building planning and design because of its increased capacities. The present state of high strength reinforced concrete design needs in-depth study to accurately predict the anticipated performance of its many component parts under dynaic lateral loading such as earthquake loads. High strength reinforced concrete is also a sophisticated and complex building material due to the large number of design and construction constraints which influence its quality, long term behavior, and final stress values. In order to more accurately model its structural response, it is necessary to develop a fundamental data-base of performance standards. The proposed project is concerned with the development of design and detailing criteria for transverse reinforcement in high rectangular columns with compressive strengths exceeding 15,000 psi. Its objectives are to determine methods to provide sufficient ductility for earthquake-resistant structures. The research plan includes both experimental and analytical studies. At least twelve large-scale column specimens will be tested and be subjected to axial and repeated lateral loads at increasing displacements. From these tests, data will be collected for the analytical documentation of the effects of concrete compressive strength, axial load, and types of transverse reinforcement on the ductility of high strength concrete columns.
