基于VB计算的倒角梁截面转换等应力法

Beam Section Transformation's Equal Stress Method Based on VB Calculation

在研究箱梁的畸变以及剪力滞的过程中,都是需要将带倒角的截面转换成直角截面,以往的方法都是等刚度原理,但是使用起来不方便.基于此,本文介绍了等应力换算的方法,得到一个一元三次方程,利用盛金公式求解,并通过VB编程,将换算过程计算机化,使得换算变得简单精确.

In the process of distortion and shear lag of box girder, to transform a chamfer section into a rectangular cross section is needed. Previous methods are stiffness principle, but is not convenient for you to use. Based on this, this paper introduces the stress conversion methods, get a cubic equation,Using ChengJin formula to solve,And through VB programming, the conversion process is computerized, making conversion simple and accurate.
