此方法的原理在于考虑一个等横截面的圆形细杆介质，在波传播到杆的一端时，产生了微小的轴向干扰。 - The section of traditional portal rigid frame are constant cross - section and wedge shape variable cross - section , this paper brings up a component cross - section ? ripple web plate variable cross - section . according to main specially characterist of portal rigid frame , this paper use matlab to work out analytical software . it ' s concrete analysis includes : endogen force and displacement caculation of rigid frame , stability analysis in and out flat surface of rigid frame , geometrical nonlinear analysis of rigid frame . and make comparison between ripple web plate variable cross - section portal rigid frame and constant cross - section rigid frame
传统的门式刚架的构件截面为等截面和楔形变截面，本论文提出了一种构件截面形式? ?波纹腹板变截面。本论文根据门式刚架的主要特点，利用matlab高级编程语言编制了4个分析软件，其针对性强，具体分析包括：刚架的内力与位移计算，刚架的平面内与平面外稳定分析，刚架的几何非线性分析。 - Based on the research to the stability variable cross - section beam , the bending defection differential equation of the variable cross - section beam in critical state of bucking is established . according to the edge condition of the structure , the differential equation is solved and bucking equation of variable cross - section beam is created . we can get the algorithm which can be used to calculate the equivalent inertia moment of the variable cross - section lattice structure when it is regarded as constant cross - section of solid web beam
对变截面格构式构件的稳定性计算进行了初步的研究,通过建立变截面构件临界状态下弯曲变形的微分方程,根据变形边界条件,得到了两端铰支的变截面梁失稳特征方程,提出了几种特殊形式的变截面格构式构件等效为等截面实腹式构件时等效惯性矩的计算方法。 - The investigation of this paper has grate actual and expansive significance and offer methods for the application of rigid frame . the investigation indicate that the ripple web plate ' s critical stress has great improvement than ordinary flat plate and ripple web plate variable cross - section has a rather superiority than constant cross - section portal rigid frame
本论文所做的研究工作具有很强的现实意义和推广意义，为门式刚架的应用提供了思路。通过研究表明：波纹腹板的临界应力比普通的平板有很大提高，而波纹腹板变截面门式刚架与等截面门式刚架进行对比也有较大的优越性。
