不同规范SRC梁柱节点抗剪承载力计算方法比较
|
摘要
简要介绍了美国、日本和我国相关规范提供的型钢混凝土节点极限抗剪承载能力计算方法。并基于已有试验研究结果,对各种计算方法所得计算结果与试验结果进行对比分析。分析结果表明,AISC规范计算SRC节点极限抗剪承载能力偏于保守,AIJ规范比较适用于设计计算,YB规程计算方法所得结果与试验结果比较接近,JGJ规程计算结果与试验结果相比偏于不安全。
Four methods to calculate the shear strength of SRC joints prescribed by AISC,AIJ,YB9082—97,and JGJ138—2001 of China were introduced.The shear strength of 18 SRC beamcolumn joints specimens were calculated using the above specifications and codes,and a comparison analysis between calculated results and test results were conducted.Comparison results indicated that among the four typical methods,the AISC specification provided a relatively conservative calculation results,the results of AIJ were more suitable for designing than other methods,the results of YB9082—97 is closest one to the test results,and the specification of JGJ138—2001 could overestimate the shear strength.
