本文按波长相等,波幅与展开长度等效的方法,将梯形波换算成正弦形波,对换算后的两种波纹形式的波形腹板构件分别在轴心受压、纯弯、压弯条件下进行了稳定承载力的对比。分析结果表明,相同受力情况下,换算前后两种波纹形式的波形钢腹板构件稳定承载力基本相同。因此,采用本文提出的不同波形折算方法,可以方便地实现不同波形腹板构件之间的等效换算。
In this paper, the equivalent of the wavelength, the amplitude and the expansion of the equivalent length of the method, the trapezoidal wave is converted to a sinusoidal wave, after the conversion of the two corrugated forms of corrugated web members were axial compression, bending, buckling conditions A comparison of stable bearing capacity was carried out. The analysis results show that under the same stress condition, the stable bearing capacity of corrugated steel web members with two corrugations before and after conversion is basically the same. Therefore, using the different waveform transformation methods proposed in this paper, the equivalent conversion between different corrugated web members can be conveniently achieved.
