【摘要】：钢结构厂房随着我国经济的快速发展应用越来越广泛,其中对大吨位的厂房需求日益倍增。随着轻型围护的发展,大吨位的厂房也越来越热衷于采用压型钢板的屋面和墙面的围护形式。因此,类似于门式刚架的大吨位厂房应运而生,在工业厂房中这种结构备受欢迎。这种结构既承接轻型门式刚架的优点又能做到大吨位吊车的布置。门式刚架平面内稳定主要是由刚架自身设计时决定,平面外稳定则由支撑体系确保。大吨位门式刚架厂房做轻型围护设计时通常结合《门式刚架轻型房屋设计规范》GB51022-2015和《钢结构设计规范》GB50017-2003。本文结合工程实例,运用PKPM软件中STS模块建立门式刚架三维模型;利用PKPM中工具箱内吊车梁模块对吊车梁进行设计,阐述了大吨位门式刚架轻型围护厂房在计算过程中的参数选取,荷载取值;详细说明了厂房的结构布置、设计原则及实际应用中的具体方法和注意事项;对钢结构厂房的刚架结构、吊车梁、支撑系统以及围护结构进行计算,分析了支撑布置情况和柱截面面积对结构的影响。对比不同柱距下各构件的用钢量及整体结构用钢量进行统计、分析、对比,得出较经济合理的柱距。经综合比较发现对于大吨位门式刚架厂房7.5m柱距优于6m柱距。相关结论可为未来相似项目的设计提供参考。
[Abstract]:With the rapid development of China's economy, the steel structure factory building is more and more widely used, and the demand for large tonnage factory building is multiplying day by day. With the development of light-duty enclosure, large-tonnage factory buildings are more and more keen to adopt the roof and wall cover of profiled steel plate. Therefore, the large-tonnage factory building similar to the portal frame emerges as the times require, and the structure is popular in industrial buildings. This structure can not only carry on the advantages of light portal frame, but also achieve the layout of large-tonnage crane. The in-plane stability of portal frame is mainly determined by the design of frame itself, and the out-of-plane stability is ensured by support system. In the design of light-duty enclosure for large-tonnage portal frame factory building, the design code for light buildings with portal frame is usually combined with GB51022-2015 and the Code for Design of Steel structures > GB50017-2003.. In this paper, the 3D model of portal frame is established by using STS module in PKPM software. The crane beam module in the toolbox of PKPM is used to design the crane beam, and the parameter selection and load value in the calculation process of light-duty enclosure building with large-tonnage portal frame are expounded. The structure layout, design principles and practical application of the factory building are described in detail. The rigid frame structure, crane beam, support system and enclosure structure of steel structure factory building are calculated, and the influence of bracing arrangement and column cross section area on the structure is analyzed. By comparing the steel consumption of each member under different column spacing and the steel quantity of the whole structure, the more economical and reasonable column spacing is obtained by analyzing and comparing. It is found that 7.5 m column distance is better than 6 m column distance for large tonnage portal frame factory building. The relevant conclusions may provide reference for the design of similar projects in the future.
