干式煤气柜圆形走道平台与一般构筑物的走道平台不同,它既要满足操作功能,又是气柜的重要受力构件,与壳体及加劲立柱共同组成空间体系,对气柜的强度与稳定起着重要作用。然而,要求解这样一个空间体系,却是一件相当困难的事情。文献〔1〕是国内目前能够见到的唯一比较完整的气柜计算资料,但对走道平台及立柱论述亦甚为简单,没有说明如何建立力学模式;而且,关于单个集中荷载作用下的圆环内力及弹性支承反力的表述,有关公式中双曲函数项被误成了三角函数,υ、v、α、β等系数亦缺乏定义,最后给出的两条实用曲线,有些系数也存在误差。为此,笔者试结合干式煤
The dry gas cabinet circular walkway platform is different from the walkway platform of a general structure. It not only meets the operation function, but also is an important force component of the gas cabinet. It forms a space system together with the shell and the stiffening column, and the strength of the gas cabinet Stability plays an important role. However, asking for a solution to such a space system is a very difficult task. The literature [1] is the only comparatively complete gas cabinet calculation data that can be seen in China at present, but it is also very simple to discuss the platform of the walkway and the column. It does not explain how to build the mechanical model; moreover, it is about the ring under a single concentrated load. The expression of internal force and elastic support reaction force, the hyperbolic function term in the relevant formula is mistaken for the trigonometric function, and the coefficients of υ, v, α, β are also lacking. Finally, for some two practical curves, some coefficients have errors. . To this end, the author tried to combine dry coal
