摘　　要：对现行国家标准中框架填充墙的构造规定进行了计算分析,结果表明其构造规定存在缺陷,即在强地震作用下,墙体出平面稳定性差,易破损及倒塌。针对上述问题,提出了框架填充墙出平面稳定设计的墙体分割法。该方法将较长的填充墙沿竖向分割成长度不超过3 m的小墙体,并设置钢筋混凝土边柱和内柱,以保证小墙体在地震作用下的出平面稳定性;填充墙与框架柱、框架梁脱开并柔性连接,在边柱和内柱顶端设置出平面限位装置;在沿墙高方向间隔500 mm的水平灰缝内以及墙顶部水平灰缝内配置2φ6通长钢筋。结果表明,在抗震设防烈度不超过9度时,墙体不会发生出平面的弯曲破坏。By calculating and analyzing the construction regulations of the frame filled wall in the current national standard,it is shown that the design is not perfect,and the stability of outside the plane of wall is poor under the action of strong earthquake,which leads to the damage and collapse.In response of the above problems,a wall partition method is proposed to calculate the stability design of frame filled wall.In this method,a long filled wall is divided vertically into small walls whose lengths equal to or less than 3 m,and reinforced concrete side columns and inner columns are set to support the small wall under plane seismic action.The filled walls are disengaged and flexibly connected with the frame column and the frame beam,and the plane limiting device is provided on the top of the reinforced concrete side column and the inner column.In the horizontal ash joint of the wall,a steel bar of 2φ6 of general length is arranged along the wall height interval of 500 mm(inside the ash joint at the top of the wall).In the earthquake crack of 9 degrees and below 9 degrees,the wall does not occur out of the plane bending failure.
