银川河东机场钢结构试验与分析研究

摘要

本文针对银川机场屋面钢结构设计中的难点、关键技术问题,进
行了结构试验、深入系统的结构分析研究,并对相应的理论作了初步
研究,为工程的顺利实施提供了有力的支持。
首先,根据结构施工图设计,按照相似原理,设计了一个 1:6 屋

拟屋架的受力机理,进行了 倍正常使用向上、向下荷载,以及破
坏荷载试验,并进行了试验分析。
另外结合钢屋架结构试验,运用大型有限元软件 ANSYS 对银川
河东机场航站楼进行了整体的静力分析、几何非线性分析,模态分析
以及地震反应谱分析。研究了整体结构应力应变的几何非线性水平,
水平地震作用下的动力响应。
针对曲拱柱承载力与设计,在基于大量数值模拟分析的实用设计

STRUCTURAL EXPERIMENTS AND ANALYSIS FOR
THE STEEL ROOF OF NEW TERMINAL BUILDINGIN
YINCHUAN HEDONG AIRPORT
ABSTRACT
According to the key design technology and difficulty problem of
Yinchuan terminal building space steel roof, the structural tests and
advanced analysis are carried thoroughly herein, and the related kick-off
theory is also performed, all guarantees the smooth realization of this
complex project.
Firstly, a 1:6 model of steel roof is designed in line with accurate
scale rule and based on the construction design drawings, pose
the triangular spider space truss, three pairs of arc arch column, SHS
beam and connector joint, etc. This reflects the mechanic property of the
whole roof. The maximum upward and down load are applied to
verify the structural performance, and the ultimate load also applied to
check the broken of the arc arch column. The experimental analysis is
comprehensively evaluated.
Furthermore, a series advanced numerical analysis are performed
using ANSYS for the whole steel roof, including plex model
static analysis, geometric nonlinear analysis, modal analysis, seismic
spectrum response analysis, et al. The nonlinear structural performances
are evaluated as stress and deflection, also the seismic dynamic response.
As the load carry capacity and design criteria concerned
