Earthquake Type Loading on R/C Beams to Column Connections with Wide Beams

抗弯R/C框架是 最常见的结构类型 系统用于低到中等 高海拔地区的高耸结构 地震风险 如果设计得当 它们的延展性非常好 系统能够承受 最强地震输入 动议 至少任两条共用 连接问题尚未得到 研究充分，即广泛 梁连接和偏心梁 连接. 由于缺乏 这两项实验研究 特殊情况，设计冲突 建议已得到 开发 宽梁连接 ACI 318委员会批准 在地震带。 然而，引用 第352章缺乏研究 不允许使用宽光束 地震带的连接。 本研究的目的是 将产生信息 通过分析和实验 对这些动物行为的研究 大型特殊连接 负载反转， 初步设计建议。 然而，这个项目的重点， 将与广泛的连接 梁。 这项研究工作是 预计开发安全设计 抗震加固准则 混凝土梁柱节点 宽梁。

Moment resisting R/C frames are the most common type of structural system used for low to moderate rise structures in regions of high seismic risk. If properly designed and detailed they are very ductile systems capable of enduring the most severe earthquake input motions. At least two common connection problems have not been adequately researched, namely wide beam connections and eccentric beam connections. Due to the lack of experimental studies for these two special cases, conflicting design recommendations have been developed. Wide beam connections are permitted by ACI Committee 318 in seismic zones. However, citing the lack of research, Committee 352 does not allow the use of wide beam connections in seismic zones. The goal of this research study will be to generate information through analytical and experimental studies on the behavior of these special connections under large load reversals and to develop tentative design recommendations. The focus of this project however, will be on connections with wide beams. This research effort is expected to develop safe design guidelines for seismic reinforced concrete beam to column connections with wide beams.
