钢筋混凝土框架填充墙的温度效应分析

Analysis of temperature effect of framed wall filled with reinforced concrete

采用ANSYS软件,将有限元方法应用于框架填充墙温度应力计算,对框架填充墙结构进行整体温度应力分析.计算分析各种温度作用对框架填充墙结构的影响,探讨结构在温度荷载作用下的不利工况,给出结构由于温度变化造成的结构内力变化范围.结果表明,可以根据在温度作用下应力、位移分布的规律和具体的数值来进行截面设计和采取相应的构造措施,使温度裂缝控制由感性上升为理性,也使采取的抗裂措施既到位又经济.

Using software ANSYS, the temperature stress in frame filled wall was calculated with finite element method, and the analysis overall temperature stress of frame filled wall was analyzed. The impact of various of temperature on the structure of frame filled wall was calculated and analyzed, the adverse conditions of the structure under temperature load were discussed, and the scope of the structural internal forces caused by temperature variation were given. The result showed that the temperature stress, displacement pattern, and their concrete values could be used to design structural sections and take corresponding measure of construction, so that the control of temperature cracks was changed from the emotional concept into rational one, and made the anti-cracking measure both proper and in place and economical.
