本文以弹性理论为根据,利用国产DJS—21型电子数字计算机,算得局部荷载及条形荷载作用下四边简支单向板的板内弯矩(?)——ρ值表,进而按文中建议的b 值一般定义进行计算,所得b 值的变化规律(即理论曲线),证实了我们在1972年试验研究基础上推荐的b值实用公式是可靠的。文中所列ρ值表可供设计研究人员参考。在集中荷载作用下一边固定悬臂板的b 值计算表明,1970年原建筑工程部建研院等单位编制的“建筑结构设计荷载”(以下简称“设计荷载”)一书中所规定的b 值公式与理论值相符。我们认为进一步用试验研究来查明是有意义的。
In this paper, based on the elastic theory, using the domestic DJS-21 electronic digital computer, the bending moment (?)-r-value table of the four-sided simple-supported unidirectional plate subjected to the local load and the strip load is calculated, and according to the suggestion in the text The b value is generally defined for calculation, and the resulting variation of the b value (ie, the theoretical curve) confirms that the practical value formula of the b value recommended by us on the basis of the experimental study in 1972 is reliable. The ρ-value table listed in the article can be used as a reference for design researchers. The calculation of the b-value of the fixed cantilever plate under the action of the concentrated load indicates that the value of b specified in the book “Architectural Structural Design Load” (hereinafter referred to as the “design load”) prepared by the Institute of Architectural Engineering and Technology of the original Building Engineering Department in 1970 The formula agrees with the theoretical value. We think it is more meaningful to use experimental research to find out more.
