钢结构桁架式通廊结构性能优化研究
|
摘要
在大跨度、高运输能力的通廊结构领域内,钢结构桁架式通廊结构是在结构受力、性价比、构件生产、安施安装方面有其特有的优势,是目前通廊结构中最常用的一种形式。为了对钢结构桁架式通廊进行性能优化研究,以武汉新洲区某煤矿钢结构桁架式单皮带通廊为例,借助理论分析和有限元建模等方法,对该结构进行了详细设计剖析,重点分析了钢结构桁架通廊的受力、桁架形式的布置、桁架节点的构造与优化设计,通过比较不同方案得出通廊结构的最优化设计方案,使得最后优化设计后的结构更适合于实际,最终实现对钢结构桁架式通廊结构性能优化设计的目的。
For the long-span corridor structure with high transport capacity,the steel truss-type corridor structure has its unique advantages in structure stress,cost performance,component production and assembly,and is currently the most commonly used corridor form. In order to study the performance optimization of the truss-type steel corridor,the paper took a truss-type single belt corridor of a steel mine in Xinzhou District of Wuhan as an example. The structure design was analyzed in detail by means of theoretical analysis and finite element modeling,and the paper analyzed emphatically the stress of the steel truss corridor, the truss form arrangement, the truss joint structure and the optimization design,and obtained the optimal design scheme of the corridor structure by comparing different schemes. The optimized structure is more suitable for the actual, and finally achieves the purpose of optimizing the structural performance of steel truss-type corridor structure.
