[提要]  規(guī)范GBJ3 - 88沒有對(duì)連續(xù)墻梁設(shè)計(jì)作出規(guī)定。現(xiàn)基于7個(gè)兩跨連續(xù)墻梁的試驗(yàn)結(jié)果討論了其受力性能和破壞形態(tài)。對(duì)2～5跨連續(xù)墻梁進(jìn)行有限元分析，依據(jù)其應(yīng)力和內(nèi)力分布，提出托梁內(nèi)力計(jì)算公式和承載力簡(jiǎn)化計(jì)算方法。基于連續(xù)拉桿拱受力模型和砌體雙向受壓強(qiáng)度導(dǎo)出墻體受剪承載力公式。給出計(jì)算實(shí)例并與其他設(shè)計(jì)方法進(jìn)行了對(duì)比。

The design regulations of continuous wall-beams are not made in the Code GPJJ3 - 88. The behaviour and modes of failure for continuous wall-beams are discussed based upon the test results of 7 specimens. The finite element analyses of 2～5 span continuous wall-beams are carried out, and the formulas for inner forces of bressummer and the simplified calculating methods of bearing capacity for the continuous wall- beams are presented. The formulas of shear capacity for the walls of continuous wall-beams are worked out based upon the force model of continuous arch and the strength of two-way compression of masonry. The calculated example and comparison between this method and others are given.
Keywords:  continuous wall-beams; experimental research; finite element analysis; calculation of bearing capacity
