［摘要］结合工程实例针对大尺度热加工重型工业厂房设计中应注意的问题进行了分析研究。设计中运用有限元软件对单层钢结构厂房进行整体空间计算，并与传统平面计算软件结果进行分析对比，得出的成果可为进一步优化结构设计、降低用钢量指标提供可靠性条件。对超宽厂房的横向温度变形进行分析，经与传统的双列柱形式对比，采用单下柱、双上柱的格构柱形式，可有效提高厂房内部使用空间。对双上柱的格构柱整体和肩梁、梁柱连接等复杂节点进行了有限元分析研究。针对厂房纵向超长的特点，进行温度应力计算，通过适当增强柱间支撑，合理布置屋面水平支撑等技术措施形成空间整体刚度体系，既满足重级工作等级厂房变形需要，确保了结构安全，又能节约一榀钢排架及其基础。针对厂房整体大跨超宽单坡屋面的建筑形式，通过分析研究，采用横向天窗刚架、屋面板可滑动支座等技术措施，较好地满足了工艺及功能需要。

Abstract: Combined with the project examples, design problems of large scale hot working heavy industrial workshop were analyzed. Finite element analysis software was used for integral space calculation of single layer steel structure. Comparative analysis was done with traditional plane calculation software. The comparative results can further provide reliability conditions for optimizing structure design and reducing steel index. Transverse temperature deformations of the ultrawidth workshop were analyzed. Compared with the traditional double columns form, lattice column with single lower column and double upper column was adopted to effectively increase the plant internal use space. The integral lattice column of double column and complex nodes of shoulder beam and beam\|column connection, etc. were researched by finite element analysis. According to the characteristics of longitudinal long, temperature stress was calculated. Through enhancing braces between columns properly, reasonable arrangement of roof horizontal supports and other technical measures, space integral stiffness system was formed, which can not only meet the deformation needs of weight level work building to ensure the safety of the structure, but also save frames and foundation. According to the whole plant construction with large span and ultra wide shed roof, through analysis and study, the lateral sunroof frame, roof panel with sliding bearings and other technical measures were adopted to better satisfy the process and function need.

Keywords: heavy industrial workshop; multiple connected span; lattice column with double upper column; lateral sunroof frame; finite element analysis; temperature deformation; stress analysis
