【摘要】：门式刚架轻钢结构已成为当今轻型化建筑结构的主要形式。它能够有效地利用材料,其构件尺寸小,重量轻,可以在工厂进行批量生产,能够保证质量,在工地安装连接方便快捷,并具有施工周期短和可循环利用的特点,因此被广泛应用于工业厂房和公共建筑中,其优越性和经济效益是不言而喻的。在门式刚架轻钢结构的工程应用中,由于某些特殊要求,使得工程设计变得比较复杂。比如工业厂房因为工艺布置或者物流输送的要求,需要有开阔的操作空间,将部分立柱抽去,因此形成了抽柱式门式刚架。关于抽柱式门式刚架的设计方法,规范中并没有进行明文规定。所以,对抽柱门式刚架的设计方法进行研究具有应用价值。本文介绍了门式刚架轻型房屋钢结构国内外发展现状和特点,以及门式刚架的基本设计理论与规范。在研究理论的基础上,归纳总结了门式刚架轻型钢结构厂房的设计方法和步骤。结合工程实例,根据工程概况,确定合理的设计方案。建立结构模型,分析结构中各个参数的设置,进行内力分析。对于抽柱式门式刚架,其工程难点在于抽柱处刚度变化对结构整体的影响。抽柱门式刚架在设计过程中采取托梁取代被抽中柱的支撑作用,懫用平面模型来建模和计算时,将其简化为弹性支座,在建立模型的过程中应该注意弹性支座约束刚度的取值。并采用纵向水平支撑及柱间支撑来加强整体刚度。最后,本文对本工程中门式刚架轻钢结构的设计计算进行了总结分析,并且指出今后需要进一步研究的问题。
[Abstract]:Portal frame has become the main form of light building structure. It can effectively use the component materials, small size, light weight, can carry out mass production in the factory, to ensure the quality, in site installation convenient connection, and has the characteristics of short construction period and can be recycled, so is widely used in industrial buildings and public buildings, the superiority and the economic benefit is self-evident. In the engineering application of portal frame, because of some special requirements, the engineering design becomes more complicated. Such as industrial layout requirements or because of logistics delivery, need to have open space that will be part of the column to smoke, thus forming a smoke column portal frame. A design method of frame column and door type pumping, specification has not been specified. Therefore, this column of portal frame Has the application value for research design method. This paper introduces the current situation of the development of portal frame light steel structure at home and abroad, and the portal frame of basic theory and design specification. On the basis of the theory, summarizes the design methods and steps of building light steel portal frame with engineering. As an example, according to the engineering situation, determine the reasonable design scheme. The structure model is established, the analysis of structural parameters set, analysis the internal force for pumping column portal frame, the engineering difficulty lies in the influence of varied stiffness of column structure of the whole pump. Support pumping column portal frame in the design process take place joist was pumped in column, Zhi to modeling and calculation using the plane model, which is simplified as elastic support, in the process of establishing the model should pay attention to value of elastic stiffness of support restraint. And the longitudinal water Flat support and braces between columns to enhance the overall stiffness. Finally, the calculation of the project portal frame light steel structure design are analyzed, and points out the problems that need further study in the future.
