[关键词] 扇形板 位移 内力 计算 解析法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.
