| National norms formulate the length of the steel building temperature area. In therange of the temperature area, the general building is hardly affected by the temperature,so the temperature stress and the temperature strain are not calculated in the design andthe impaction of temperature on steel structures is seldom considered. Super profiledsteel structures have a large stiffness. They have a strong binding on the core area of thebuilding. It has a greater thermal stress. The temperature stress expands from the middleto the two terminals of the structures which leads to a gradual increase of deformation.The thermal stress and deformation must be considered in the design and calculation.With field testing and numerical simulation in the Shougang steel plant, its thermalstress and strain are studied. The Shougang Jingtang Company’s second cold rolling millis a large steel structure. TDS303static strain gauge is used to monitor the temperaturestress of the plant. T1030R3total station device is used to monitor the temperaturedeformation. At the same time, ANSYS software is used to simulate this plant. The dataof the temperature stress and the temperature deformation are analyzed.Studying on the influence of the temperature on large steel structures, the7th plantof Mcc Hengtong cold rolling technology Co. Ltd is on the whole simulated with theANSYS software and PKPM software. The temperature stress and the temperaturedeformation in the large plant are comprehensively analyzed. At the same time, it usesthe two ways of “anti†and “release†and three approaches to release the temperaturestress and control the temperature deformation of the structures. The first approach by the“anti-†method is to increase the cross-section of the column and beam. The secondapproach by the “release†method is to set expansion joints with a frame. The thirdapproach is to establish the release area of the temperature stress in the temperature fixedpoint. Three scenarios are analyzed and compared. |
