摘　　要：根据四边简支板的重三角级数解,巧妙应用简支梁跨中受局部荷载与四边简支双向板受局部荷载时内力间的比拟关系,由四边简支双向板受均布荷载和局部荷载时内力等值条件,导出一种集中荷载作用下双向板等效均布荷载的计算方法,据此编制计算机程序,分析荷载作用面变化对等效荷载取值的影响,便于合理确定等效荷载。According to the four sides non-fixed plate's retriangle series solution,it was skillfully applied the curving comparison relation between the both ends non-fixed beams under partial loads and the four sides non-fixed plates under partial loads.From their equivalent relation of the internal force,it was derived a method of the equivalent uniform distrubuted load computing the four sides non-fixed plate in the concentrated loads.Programming on these grounds,it was analysed the effect of span and load-acting area,etc on the value of equivalent loads.It is Convenient to reasonably determine equivalent load.
