【摘要】：加固砌體結(jié)構(gòu)和框架結(jié)構(gòu)的方法有很多,但多是加固受損構(gòu)件。且由于加固施工影響面積大,受影響人數(shù)多,因此不能滿足當(dāng)前社會(huì)需要。本論文提出的分散筒加固法是一種新型的加固方法。即在建筑結(jié)構(gòu)中只加固結(jié)構(gòu)兩端,并使加固部分形成筒體結(jié)構(gòu)。加固對(duì)象為抗壓滿足但抗震不滿足規(guī)范要求的砌體結(jié)構(gòu)和框架結(jié)構(gòu)。加固后的建筑結(jié)構(gòu),結(jié)構(gòu)體系改變,結(jié)構(gòu)傳力路徑發(fā)生變化。該方法與傳統(tǒng)加固方法比,具有加固工程量小,施工影響范圍小,材料利用率高,加固成本低等諸多優(yōu)點(diǎn)。通過(guò)加固砌體結(jié)構(gòu)(鋼筋混凝土面層法和分散筒法加固)和框架結(jié)構(gòu)(增設(shè)剪力墻法和分散筒法加固),分析兩種加固方法下,結(jié)構(gòu)的剛度,加固、未加固構(gòu)件的內(nèi)力,加固費(fèi)用等幾方面,比較傳統(tǒng)法與分散筒法的優(yōu)劣。為了推廣這種新型加固方法,本文開(kāi)展的主要工作和相關(guān)結(jié)論有：(1)通過(guò)將砌體等剛度代換板墻,建立剛度等代模型,解決了在PKPM軟件砌體加固模塊中不能計(jì)算混凝土板墻剛度的問(wèn)題,為以后的研究應(yīng)用提供依據(jù)；(2)在分散筒加固計(jì)算中,提出在PKPM中考慮加固筒體的空間效應(yīng)的方法,提高了材料強(qiáng)度的利用率;(3)提供了利用分散筒法加固砌體結(jié)構(gòu)和框架結(jié)構(gòu)的計(jì)算步驟：(4)對(duì)于多層砌體結(jié)構(gòu),分散筒加固法比板墻加固法可以更大程度提高結(jié)構(gòu)抗側(cè)剛度,且能減小未加固構(gòu)件的地震作用及結(jié)構(gòu)加固成本；(5)對(duì)于多層框架結(jié)構(gòu),分散筒法比增設(shè)剪力墻法可以更大程度提高結(jié)構(gòu)剛度,且能減小未加固構(gòu)件的地震作用及結(jié)構(gòu)加固成本。
[Abstract]:There are many ways to strengthen masonry structure and frame structure, but most of them are to reinforce damaged members. Therefore, it can not meet the needs of the current society. The method proposed in this paper is a new type of reinforcement method, that is, only the two ends of the structure are strengthened in the building structure. The reinforced part is made into a tube structure. The reinforced object is masonry structure and frame structure which can not meet the requirements of the code. The reinforced building structure and structure system are changed. Compared with the traditional reinforcement method, this method has the advantages of small amount of reinforcement works, small scope of construction influence, and high material utilization ratio. Through strengthening masonry structure (reinforced concrete surfacing method and dispersed tube method) and frame structure (adding shear wall method and dispersed tube method to reinforce), the paper analyzes the two reinforcement methods. In order to popularize this new reinforcement method, the stiffness of the structure, the reinforcement, the internal force of the unstrengthened members and the cost of the reinforcement are compared between the traditional method and the dispersed tube method. In this paper, the main work and related conclusions are: 1) by replacing the plate wall with the equal stiffness of masonry, the equivalent stiffness model is established. It solves the problem that the stiffness of concrete slab wall can not be calculated in the masonry reinforcement module of PKPM software, and provides the basis for future research and application. 2) the method of considering the spatial effect of the strengthened cylinder in PKPM is put forward, which improves the utilization ratio of the material strength. This paper provides the calculation steps of strengthening masonry structure and frame structure by using dispersed tube method. For multistory masonry structure, the method of dispersive tube reinforcement can improve the lateral stiffness of the structure to a greater extent than the plate wall method. And it can reduce the seismic action of unstrengthened members and the cost of structural strengthening. 5) for multi-story frame structure, the dispersion tube method can improve the stiffness of the structure more than adding the shear wall method, and can reduce the seismic action of the unstrengthened members and the cost of strengthening the structure.
