(哈爾濱工業(yè)大學(xué)深圳研究生院城市與土木學(xué)科部，深圳 518055)［摘要］對金屬面巖棉夾芯墻面板進(jìn)行了抗剪性能試驗(yàn)，根據(jù)試驗(yàn)結(jié)果進(jìn)行有限元模擬，最后根據(jù)試驗(yàn)與有限元結(jié)果的對比進(jìn)行理論分析。結(jié)果表明，墻面板連接節(jié)點(diǎn)破壞的主要原因是，自攻螺釘由于受到剪力作用，在其與檁條連接處產(chǎn)生力矩，使其發(fā)生傾斜，導(dǎo)致自攻螺釘帽斜向接觸墻面板，導(dǎo)致局部壓力過大，使鋼板屈服，最終節(jié)點(diǎn)破壞。通過分析，得出了節(jié)點(diǎn)抗剪承載力設(shè)計公式，為以后節(jié)點(diǎn)設(shè)計及相關(guān)規(guī)范制定提供了參考。［關(guān)鍵詞］彩鋼巖棉夾芯墻面板；節(jié)點(diǎn)抗剪；有限元Experiment and theoretical study on joint shearing capacity of the color steel sandwich panels filled with rock woolZhang Fengliang，Zha Xiaoxiong，Huang Yuzhong(Civil Engineering, Harbin Institute of Technology Shenzhen Graduate School, Shenzhen 518055, China)Abstract:The shearing capacity experiment was carried out on the color steel sandwich panels filled with rock wool to study the destructive capacity and behavior. According to the result of the tests,the finite element method was used to do the theory analysis. From the result,the main reason which leads to the failure of the joint is that, the self-threading screw is gradient when the force moment is created at the connection, and the cap of screw is contacted with the single nail in a certain angle, which leads to high pressure in the local part and makes the steel plate yielding. By the finite element and theory analysis, the design formula of joint shearing capacity is got, which will be good references for design and code of the joint.Keywords:the color steel sandwich panels filled with rock wool; joint shearing; finite element method深圳市科技計劃項(xiàng)目和深圳市南山區(qū)科技計劃項(xiàng)目。作者簡介：張鳳亮，碩士，Email:fl_0206@yahoo.com.cn。參考文獻(xiàn)［1］田政明.彩鋼板墻面的施工［Ｊ］.建筑安全.2006，21（7）．［２］鄭小青, 沈?qū)W毅. 彩鋼夾芯板及其應(yīng)用［Ｊ］. 水運(yùn)工程. 2002（12）．［３］張帆, 馮玉萍. 金屬面夾芯板的選用與施工［Ｊ］. 河南建材. 2001（3）．［４］聚氨酯泡沫夾芯板結(jié)構(gòu)性能試驗(yàn)報告［Ｒ］. 北京：中國建筑研究院結(jié)構(gòu)所. 1988.［5］汪一駿. 鋼結(jié)構(gòu)設(shè)計手冊(第三版)［Ｍ］. 北京：中國建筑工業(yè)出版社, 2004.［6］HOFF N J, MAUTNER.
