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 heavy triangle series solution of simple support plate on four sides, cleverly applying the comparison of the internal forces at the time when the two-way plate subjected to local loads by simply supported beams and by the local load, A method of calculating the equivalent uniform load of two-way slab under concentrated load is derived. Based on this, a computer program is compiled to analyze the effect of the change of load acting surface on the equivalent load value so that the equivalent equivalent load can be reasonably determined Load.
