抗震横墙间距的大小对内框架房屋的抗震能力影响很大,从多项地震危害表明,横墙间距大时震害就严重,因此,正确选定横墙间距是保证内框架房屋抗震能力的一个关键,本文针对唐山地震后石家庄新建的内框架房屋在确定横墙间距时存在的问题和改进措施简介于后: The size of the seismic wall spacing has a great influence on the seismic capacity of the interior frame houses. From the multiple earthquake hazards, it is shown that when the spacing between the walls is large, the damage is severe. Therefore, the correct selection of the space between the walls is to ensure the earthquake resistance of the interior frame houses. One key point: This paper describes the problems existing in determining the spacing of cross walls between the newly built inner frame houses in Shijiazhuang after the Tangshan earthquake and the improvement measures.
