原文承郑朝强与潘江二同志写出讨论并各提出另一种计算变梁常数的方法来和I_0/I,余图法比较,这表示他们对于变梁常数的计算与笔者同样感到兴趣。在答复郑、潘二同志的讨论之前,笔者想先就下列两点扼要说明: (一)变梁常数的计算法与变梁类型的关系——变梁可分为下列三大类型: 1.只有突变而无渐变的阶形梁, 2.通用形式的矩形截面加腋梁, 3.非通用形式的渐变梁,例如梁腋的曲线不能用算式来表示(也就是不能用求积分法来计算它们的常数),或非矩形截面的渐变梁,例如工字形或槽形截面的渐变梁,或兼有突变与渐变的变梁。
The original writer Cheng Chaoqiang and Pan Jiang comrades wrote discussions and proposed another method to calculate the variable beam constants to compare with I_0/I and the residual graph method. This indicates that they are also interested in the calculation of variable beam constants. Before answering the discussions of Comrades Zheng and Pan, I would like to briefly explain the following two points: (1) The relationship between the method of calculating the variable beam constant and the type of variable beam—the beam can be divided into the following three types: 1. Only the gradient beam with abrupt change without gradient, 2. The rectangular beam with general shape and twist beam, 3. The beam with non-universal form, such as beam beam, cannot be represented by formula (that is, cannot be calculated by integral method. Their constants), or gradient beams with non-rectangular cross-sections, such as gradient beams with I-shaped or grooved sections, or variable beams with both mutations and gradients.
