摘要:
温度作用是结构设计中不可忽视的作用,如何有效控制温度作用一直是一个重要的课题。近些年,随着建筑和结构的发展,出现越来越多的超长结构和隔震结构。对于超长结构的温度效应有许多学者做过相关的研究,但超长隔震结构的温度效应还研究甚少,温度作用下的结构变形和内力特点还不甚明晰。对超长剪力墙隔震结构的温度效应进行了探讨,利用有限元软件ETABS建立了结构的隔震模型和非隔震模型。通过对比2种模型在季节温差和混凝土收缩当量温差共同作用下的结构变形特点、构件内力和应力大小,分析隔震支座变形量与所在位置关系,发现超长隔震结构较超长非隔震结构,隔震层以上结构由于约束释放在温度作用下接近自由变形。而结构构件的内力和应力大大减小,得出隔震支座能充分消除结构因温度效应产生的不利影响,从而保护结构和构件的结论,对超长隔震结构的温度效应控制提供一定的思路和参考。
Abstract:
The temperature effect is non-negligible in structural design and how to effectively control the effect of temperature is an important issue. In recent years, with the development of the architecture and structure, more and more super-length structures and isolated structures have appeared. Many scholars have done relevant research on the temperature effect of the super-length structures,but the temperature effects on isolated super-length structure have been still rarely studied and the deformation and internal force characteristics are still not very clear. The temperature effect of the isolated super-long shear wall structure is discussed in this paper. The isolated model and the non-isolated model of the structure are establishedusing the finite element software ETABS. Comparisons of the deformation and internal force characteristics of the two models subjected to seasonal temperature difference and concrete shrinkage equivalent temperature difference simultaneouslyare conducted. The relationships between the deformation and locations of isolators are analyzed. Results show that compared with the super-length non-isolated structure, the part of super-length isolated structure above the isolation layer is close to free deformation under the action of temperature, and the internal force and stress of the components are significantly reduced. Therefore it can be concluded that the isolator can adequately eliminate the adverse effects of the structure due to temperature, thus protecting the structure and components. A reference on temperature control for the isolated super-length structure is provided.
