［摘要］簡(jiǎn)要介紹了美國(guó)、日本和我國(guó)相關(guān)規(guī)范提供的型鋼混凝土節(jié)點(diǎn)極限抗剪承載能力計(jì)算方法。并基于已有試驗(yàn)研究結(jié)果，對(duì)各種計(jì)算方法所得計(jì)算結(jié)果與試驗(yàn)結(jié)果進(jìn)行對(duì)比分析。分析結(jié)果表明，AISC規(guī)范計(jì)算SRC節(jié)點(diǎn)極限抗剪承載能力偏于保守，AIJ規(guī)范比較適用于設(shè)計(jì)計(jì)算，YB規(guī)程計(jì)算方法所得結(jié)果與試驗(yàn)結(jié)果比較接近，JGJ規(guī)程計(jì)算結(jié)果與試驗(yàn)結(jié)果相比偏于不安全。

Comparative study on the shear capacities of SRC joints prescribed in different codes

Zhuang Yun, Guo Zixiong(College of Civil Engineering of Huaqiao University, Quanzhou 362021, China)

Abstract: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 beamcolumn 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.

Keywords:steel reinforced concrete; joints; ultimate shear strength; calculation method
