摘要
根据截面抗弯刚度相等和应变能相等两个原则 ,将有踏步的变截面梯段板转化为等截面板 ,从理论上分析了踏步对梯段板抗弯刚度和变形的有利影响 ,并与试验结果进行了对比 结果表明 ,踏步对梯段板的抗弯刚度有较大影响 ,如能考虑这一影响 ,将使板式楼梯的设计更为轻巧。
On the basis of stiffness equivalent and strain energy equivalent,the vari- section stair plate with steps is changed to the equi-section plate.The effect of steps on the stiffness and deformation of the stair plate is analyzed and compared with test results.If the good effect of steps is considered,the design of plate stairs will be more beautiful and economical.
