平鲁工业园区输煤系统栈桥钢支架布置方式及设计方法的探讨

摘要

There are many layouts of coal transport trestle steel supporting structures ,such as single steel sheet support-ing structure ,lattice steel supporting structure and four pillars steel supporting structure .Generally the bracket arrange-ment in the concrete engineering is in different heights and different support forms are used .Based on the finite element analysis of the whole model ,this paper proposed a new method for the arrangement of the transport trestle support ,which combines two kinds of steel bracket single steel sheet supporting structure and four pillars steel supporting structure to-gether ,the new method could enhance the seismic performance of the unit structure and reduce material waste for influ-ence of effective length factor .%输煤栈桥钢支架的布置形式一般包括：单片式钢支架、格构式钢支架、四柱式钢支架。通常具体工程中的支架布置方式是：在不同的高度下，采用不同的支架形式布置。通过对整体模型进行有限元分析，重新对栈桥支架布置方式进行探讨。采用两种钢支架形式（单片式钢支架、四柱式钢支架）组合在一起的方式，形成单片＼四柱单元式钢支架，增强单元内结构的抗震性能，减少因计算长度系数的影响而形成的材料浪费。
