The loading capacity, dissipation capacity, hysteretic characteristics and deformability of joint core area and so on were analyzed. The results show that increasing thickness of the built-in steel plate can improve the bearing capacity of beam-wall joint, but make little impact on the ductility. The ductility and the bearing capacity of the beam-wall joints with the stud arrangement on all the built-in steel plate are better than that with the stud arrangement on the anchorage zone of built-in steel plate.Keywords: built-in steel plate; beam-wall joint; thickness of steel plate; stud arrangement; mechanical performance*國(guó)家財(cái)政部科研課題，中建股份科技研發(fā)課題(CSCEC-2010-C-05)。作者簡(jiǎn)介：陳勇，博士，教授級(jí)高級(jí)工程師，碩士生導(dǎo)師，Email：dr_cy@126.com。參考文獻(xiàn)［1］彭偉. 高層建筑結(jié)構(gòu)設(shè)計(jì)原理［M］. 成都：西南交通大學(xué)出版社，2004.［2］YB 9082—2006 鋼骨混凝土結(jié)構(gòu)技術(shù)規(guī)程 ［S］. 北京：冶金工業(yè)出版社，2007.［3］GB 50010—2010 混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范 ［S］. 北京：中國(guó)建筑工業(yè)出版社,2011.［4］JGJ 101—96 建筑抗震試驗(yàn)方法規(guī)程 ［S］. 北京：中國(guó)建筑工業(yè)出版社,1996.［5］姚謙峰, 陳平. 土木工程結(jié)構(gòu)試驗(yàn)［M］. 北京：中國(guó)建筑工業(yè)出版社，2003.［6］朱炳寅.高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程應(yīng)用與分析JGJ 3—2010［M］.北京：中國(guó)建筑工業(yè)出版社，2012.［7］PARK WAN SHIN, YUN HYUN DO.
