它由内核与套筒组成，且两者之间有间隙，套筒为受压内核提供侧向约束，使得内核可以发生高阶屈曲模态，极大提高了内核的受压承载力。

A simplified mechanical model of a typical axially loaded sleeved compression member is introduced. Some reasonable constitutive relation curves of the inner steel tube are chosen for analyzing in two numerical examples. One is analysis on its axially loaded bearing capacity under different working conditions. The other is stability analysis of grid structure with SCM. The buckling control effect of the inner steel tube is evaluated with the outer steel tube applied in these conditions.

The web perforation can provide space for electrical conduits and bracing. Therefore, it has the meanings and motive for the study of C-shaped section with web openings. The strength of a compression member can be influenced by the section shape, thickness of section, length of member, and support condition.

不过，构材之厚度、加劲与未加劲、是否开孔、上下两端之接合方式，皆会影响受压构材之抗压能力，所以目前先针对C形断面构材的开孔与否及上下两端之接合方式，分别以两种尺寸来讨论，并藉由有限元素分析软体ANSYS 6.0版，来模拟构件受压时，断面的应力分布情形。

The paper describes how the local force of the main web is considered as the force caused by the Contact pressure among the trolley wheel, rail and top flange, and how the contact analysis model for the local force is built by means of both Hertz theory and finite element software ANSYS combined. Also, it analyzes the variation of the local stress under the different conditions and comes to a conclusion, and compares the results derived from the experimental formula with the result from ANSYS.

本论文的主要内容：将Hertz接触理论和有限元软件ANSYS结合起来，把主腹板的局部受力问题视为小车轮与轨道及轨道与上翼缘板之间发生接触行为作用下的受力问题，建立了小车轮压作用处偏轨箱形梁主腹板局部受力的接触分析模型，研究不同情况（小车轮压、箱形梁几何参数和轨道截面惯性矩）下局部应力的变化规律，得出相关结论；最后将经验公式解与ANSYS数值解进行对比分析论证。
