【摘要】 按规范GBJ11－89设计的多层砖房，很难保证大震不倒．本文提出在基础圈梁上用两片瓷砖形成的摩擦面构成薄弱层的方法，通过控制摩擦系数大小来控制地震时地震作用的大小，这样可以很好地解决这个大震不倒的问题．更多还原

【Abstract】 The housc designed according to the standard GBJ11-89 is difflcult to ensure not io collapse. This paper plovides the method of setting up weak section upper the brick house foundation girth,which made up of two picces of ceramic tile,it can contrl the carthquake ac- tion by controlling the coeficlent of friction. So it is easy to solve that brick house doesn .t collapse in rare earthquake.更多还原
