equivalent beam width

The method for calculating the equal-section equivalent beam width is presented and the stiffness of the equivalent beam equals to the slab stiffness.

同时按刚度相等原则，给出了折算成等截面等代梁宽度的计算方法。

We put the concrete flange plate of the composite beam into the steel ones according to the elastic modulus ratio and keep the width of section unchanged, as a result, get a equivalent section.

将组合梁中混凝土翼缘板厚度按弹性模量之比换算，并保持宽度不变形成等效截面。

The mean-square width and the equivalent-beam width are put forward to investigate the spreading of vortex beam while propagating.

提出了均方根光斑尺寸以及等效光斑尺寸的定义，并分别采用这两种定义对涡旋光束的光斑展宽进行了分析。
