网架在造船工业工程中的应用综述

Summary of Application of Space Trussesin Ship building Industrial Engineering

近七年来，造船工业工程中有１３个工程项目，近２３００００ｍ２屋盖采用了网架结构屋盖。本文对应用中存在的共性问题：大跨度工业厂房中，网架结构的最佳形式；网架屋面在单层厂房中的排架分析计算假定；网架同柱的支承节点构造上如何按排架铰接计算的假定；墙架柱同网架的连接节点等方面进行了总结，以使网架结构能在单层工业厂房中的应用技术日臻完善。

Space grid roof has been used in 13 projects (about 23000m2) in shipbuilding industrial engineering in the past seven years. In order to perfect the application technology of space grids insingle story factory, the following generality problems have been summarized in this paper: (l) thebest type of space grids for large span factory; (2) the calculation hypothesis of space grids for analyzing bent frame in single story factory; (3) the construction of the support joint connecting spacegrid and column according to the hinge joint calculation hypothesis used in analyzing bent frame;(4)the joint connecting space grid with wall column.
