扇形板的位移和内力计算

Displacement and Internal Force Calculation of Sectorial Plates

采用无穷级数解析法推导了沿直线边简支、沿圆弧边简支或固支的各种扇形板的位移和内力计算公式,并给出了几种不同顶角的扇形板在均布面荷载和均布线荷载作用下位移和弯矩的实用计算表格,可供设计时查表选用,亦可供其它接近扇形板的异形板作近似计算用.

The displacement and internal force formula of various angle sectorial plates, simply supported on the linear edge and simply or fixed supported on the arc edge, is derived by an infinite series theoretical method. Based on the formula, the authors give the deflection and bending moment's practical calcula-tive forms of sectorial plates under a uniformly distributed vertical load unit area and unit length.
