摘要
矩形水池计算目前大多采用查表法,矩形地面式水池单位宽度池壁沿高度的水平地震作用为正弦分布形式的荷载,目前可查表格中缺少此类荷载的弯矩系数表格,借助ANSYS程序,对三边固定顶端自由、三边固定顶端铰接两种形式的双向板,进行了在该荷载分布作用下的有限单元分析,得到了方便应用于实际工程中的弯矩系数表格,数值拟合了公式,并与简化为倒三角形荷载分布的池壁计算进行了比较。
To calculate rectangular reinforced concrete tank,the common way is to look up tables.The horizontal earthquake action of rectangular reinforced concrete tank is sinusoid from the bottom to top of vertical tank slab.However,the coefficient tables for this type of load are not available.By using ANSYS program and observing the tank slab of three borders fixed one border free and three borders fixed one border simple,this article analyzes the tank slab under the action of this type of load,obtains the bending moment coefficient table and the calculation formula which can be used conveniently in practical engineering project,and compares it with the results when the load is simplified to converse triangle load.
