摘要
由于我国2007年10月发布的《铝合金结构设计规范GB50429—2007》采用有效厚度法计算铝合金构件的有效截面特性,需要进行反复迭代,并且若同时考虑局部屈曲和焊接对构件截面厚度的折减,则计算变得更加复杂,不方便工程应用,因此基于该规范采用VC++.NET开发基于有效厚度法的铝合金构件有效截面特性计算软件.对于铝合金构件在受轴向力、单向受弯、单向压弯、双向受弯和双向压弯等情况下,该软件实现常用焊接或者挤压成型工字形、槽形、矩形、C形以及带肋矩形截面的有效截面形状自动绘制和截面特性自动计算.实例表明该软件能够提高铝合金结构设计和计算的效率及准确性,有助于该规范的推广使用.
In the Code for Design of Aluminum Structures deployed by China in Oct. 2007, effective thickness method is used to calculate the effective section properties of aluminum alloy members. The calculation needs repeating iteration and it becomes more complicated and is not convenient for application if the effect on section thickness of local buckling behavior and welding are both taken into account. So the calculation software of effective section properties of aluminum alloy members based on effective thickness method is developed by VC ＋＋. NET according to the specification. The effective section properties of welded or extruded aluminum alloy members, which are I-shaped, slop-shaped, rectangle, C-shaped or rectangle section with ribs, can be automatically formed and the effective section properties can be calculated under the conditions of axial force, unidirectional bending, unidirectional compression bending, biaxial bending and so on. The examples demonstrate that the software can improve the design and calculation efficiency of aluminum alloy structures and is helpful to popularize the specification.
