本文提供了运用屈服线分析法编制的各种支承情况下,承受均布荷载的三种普通三角形板弯矩系数计算图表。并选用了适用于大多数实际情况范围内,负钢筋与正钢筋及正交各向异性钢筋的各种比值,并设法推荐钢筋的最优值。设计师在实际工作中,运用本计算图表能设计出比较优化或比较经济的三角形板。 This paper provides the calculation formulas of bending moment coefficient of three kinds of common triangular plates subjected to uniform load under various support conditions by using the yield line analysis method. The ratios for negative reinforcement and normal reinforcement and orthotropic reinforcement in most practical situations were selected and the best values ​​for reinforcement were sought. Designers in the actual work, the use of this calculation chart can be designed to more optimal or more economical triangle plate.
