Earthquake Type Loading on R/C Beam - Column Connections: Special Cases of Wide Beams and Eccentric Beams

研究了两种特殊类型钢筋混凝土梁柱连接的非弹性抗震性能。这些特殊情况存在于(1)梁中心线不与柱中心相交以及(2)梁截面比柱宽的情况下。这两种情况在钢筋混凝土延性框架建筑的正常设计中都得到了缓解，但现行设计规定的准确性和安全性尚不确定。一项实验研究计划包括至少八个梁柱连接的模拟地震测试，上述每种特殊情况中有四个将进行。还将进行一项补充分析调查，以验证测量结果，并将结果扩展到具有这种特殊连接的R/C框架结构的预期动力响应的预测。该项目的最终目标将是验证现有设计条款或修订需求的建议。

The inelastic seismic behavior of two special types of reinforced concrete (RIC) beam- column connection is investigated. These special cases exist in situations where (1) the beam centerline does not intersect the column center, and (2) the beam section is wider than the column. Both cases are remitted in normal design of R/C ductile frame buildings but the accuracy and safety of current design provisions has been uncertain. An experimental study program consisting of simulated earthquake testing of at least eight beam-column connections, four of each special case noted above will be conducted. A complimentary analytical investigation will also be carried out to verify the measured results and extend the results into a prediction of the expected dynamic response of R/C frame structures with such special connections. The final goal of the project will be a verification of existing design provisions or proposals for revised requirements.
