【摘要】：近年來,隨著我國GDP的穩(wěn)步增長以及建筑市場的逐漸好轉(zhuǎn),很多大城市中的停緩建工程(爛尾樓)也都重新啟動,需要對建筑物進(jìn)行檢測鑒定和改造加固工作。目前在理論研究方面對結(jié)構(gòu)加固改造的整體分析的研究尚不完善�，F(xiàn)行規(guī)范對加固的整體分析也提及不多。本文對在役高層建筑的加固改造整體分析進(jìn)行研究,具有重要的現(xiàn)實意義。 本論文在對建筑物加固改造方法的研究和應(yīng)用現(xiàn)狀進(jìn)行了簡單闡述的基礎(chǔ)上,介紹了結(jié)構(gòu)加固改造的具體方法步驟。結(jié)合工程實例,對實例工程進(jìn)行了檢測鑒定；借助PKPM軟件和SAP2000軟件,對加固前的結(jié)構(gòu)進(jìn)行了建模分析,得出結(jié)構(gòu)在加固前的受力性能和變形情況；對結(jié)構(gòu)加固后可能引起的整體性能變化進(jìn)行了詳細(xì)分析,并對加固改造前后的結(jié)果進(jìn)行了對比分析,驗證了加固改造方法的安全性和可行性；在對結(jié)構(gòu)進(jìn)行加固改造后的基礎(chǔ)上,對不同的地震條件下的加固后結(jié)構(gòu)進(jìn)行整體性分析,并分別對不同地震條件下的計算結(jié)果進(jìn)行了對比分析。本文主要是對結(jié)構(gòu)的加固改造進(jìn)行整體分析,為這一方面的研究提供理論依據(jù)。 本文的相關(guān)問題的研究和討論,將為今后相關(guān)類似的結(jié)構(gòu)加固改造提供一些理論參考。
[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.
