某在役高层建筑结构加固改造对结构性能影响的分析研究
发布时间：2018-07-16 23:59
【摘要】：近年来,随着我国GDP的稳步增长以及建筑市场的逐渐好转,很多大城市中的停缓建工程(烂尾楼)也都重新启动,需要对建筑物进行检测鉴定和改造加固工作。目前在理论研究方面对结构加固改造的整体分析的研究尚不完善。现行规范对加固的整体分析也提及不多。本文对在役高层建筑的加固改造整体分析进行研究,具有重要的现实意义。 本论文在对建筑物加固改造方法的研究和应用现状进行了简单阐述的基础上,介绍了结构加固改造的具体方法步骤。结合工程实例,对实例工程进行了检测鉴定；借助PKPM软件和SAP2000软件,对加固前的结构进行了建模分析,得出结构在加固前的受力性能和变形情况；对结构加固后可能引起的整体性能变化进行了详细分析,并对加固改造前后的结果进行了对比分析,验证了加固改造方法的安全性和可行性；在对结构进行加固改造后的基础上,对不同的地震条件下的加固后结构进行整体性分析,并分别对不同地震条件下的计算结果进行了对比分析。本文主要是对结构的加固改造进行整体分析,为这一方面的研究提供理论依据。 本文的相关问题的研究和讨论,将为今后相关类似的结构加固改造提供一些理论参考。
[Abstract]:In recent years, with the steady growth of China's GDP and the gradual improvement of the construction market, a lot of slow construction projects (uncompleted buildings) in large cities have also been restarted, so it is necessary to carry out inspection, appraisal and reconstruction and reinforcement of buildings. At present, the research on the whole analysis of the reinforcement and reconstruction of the structure is not perfect in the aspect of theoretical research. The overall analysis of reinforcement in the current code is not much mentioned. It is of great practical significance to study the whole analysis of reinforcement and reconstruction of existing high-rise buildings in this paper. On the basis of a brief description of the research and application of the methods of reinforcement and reconstruction of buildings, this paper introduces the concrete methods and steps of structural strengthening and reconstruction. Combining with the engineering example, the paper tests and appraises the case engineering, with the help of PKPM software and SAP2000 software, models and analyses the structure before reinforcement, and obtains the mechanical behavior and deformation of the structure before reinforcement. The possible overall performance changes after reinforcement are analyzed in detail, and the results before and after reinforcement are compared and analyzed to verify the safety and feasibility of the reinforcement and reconstruction method. On the basis of strengthening and reforming the structure, the whole structure under different earthquake conditions is analyzed, and the calculation results under different earthquake conditions are compared and analyzed. In this paper, the reinforcement and reconstruction of the structure is analyzed as a whole, which provides the theoretical basis for this research. The research and discussion of the related problems in this paper will provide some theoretical references for the reinforcement and reconstruction of similar structures in the future.
