【摘要】：節(jié)能、環(huán)保、可持續(xù)發(fā)展對(duì)建筑技術(shù)提出新的要求,提高住宅產(chǎn)業(yè)化、現(xiàn)代化水平是實(shí)現(xiàn)綠色建筑的重要途徑。從住宅產(chǎn)業(yè)化發(fā)展經(jīng)驗(yàn)來看,通過建筑體系標(biāo)準(zhǔn)化、技術(shù)應(yīng)用集成化建造的住宅,既能滿足人們對(duì)住房的需求,又能提高住宅的綜合性能。更重要的是它符合可持續(xù)理念,是實(shí)現(xiàn)綠色建筑、綠色施工的重要途徑。資料表明,住宅的預(yù)制率達(dá)37%時(shí),可節(jié)約用水36%,垃圾減少83%,材料損耗減少60%,節(jié)約用電31%以上,節(jié)能50%以上。因此,提高工業(yè)住宅化和現(xiàn)代化已成為我國住宅發(fā)展的的必由之路,預(yù)制裝配式混凝土結(jié)構(gòu)已然成為未來建筑結(jié)構(gòu)體系的發(fā)展方向。 根據(jù)預(yù)制外墻板作為裝配式混凝土結(jié)構(gòu)的重要組成部分。本課題針對(duì)沈陽地鐵·麗水新城裝配式剪力墻結(jié)構(gòu)預(yù)制外墻板出現(xiàn)的問題進(jìn)行分析研究。首先,對(duì)預(yù)制墻板與內(nèi)側(cè)剪力墻之間由保溫填充材料改為混凝土澆筑,致使預(yù)制墻板對(duì)整體結(jié)構(gòu)的約束增強(qiáng)、剛度增大,導(dǎo)致結(jié)構(gòu)自振周期需要折減。因此,采用PKPM中的SATWE計(jì)算自振周期折減系數(shù)。再利用MIDAS/Gen有限元軟件對(duì)預(yù)制模板結(jié)構(gòu)模型進(jìn)行彈塑性靜力分析,驗(yàn)證主體結(jié)構(gòu)在多遇地震和罕遇地震下的抗震性能。針對(duì)預(yù)制外墻掛板作為預(yù)制混凝土模板(以下簡(jiǎn)稱預(yù)制模板)進(jìn)行使用,以及實(shí)際施工時(shí),上下齒口完全脫離,齒口處采用水泥砂漿抹平,無法實(shí)現(xiàn)面外限位,造成外掛板面外受力方式完全改變,同時(shí)由于墻體現(xiàn)澆混凝土的側(cè)向壓力,使得外掛板在面外方向脹模,影響外掛板的結(jié)構(gòu)安全。因此,利用MIDAS/Gen有限元軟件對(duì)外墻模板在使用階段和施工階段進(jìn)行受力分析,提出外墻板的補(bǔ)強(qiáng)方案。 對(duì)裝配式夾心保溫外墻板而言,連接件是最重要的重要的部分之一。為進(jìn)一步對(duì)預(yù)制外墻板的深入研究,本文針對(duì)以3600×3000(包含開窗1500×1800)預(yù)制夾心保溫外墻板為基礎(chǔ),采用纖維筋作為連接件,利用ABAQUS建立計(jì)算模型對(duì)其進(jìn)行有限元受力分析,驗(yàn)證不同形式的纖維筋連接件能夠滿足受力要求,并形成完整的技術(shù)方案,為新型連接件的應(yīng)用提供技術(shù)支持。 最后,總結(jié)了本文的研究成果,解決工程實(shí)際應(yīng)用上的技術(shù)難題,進(jìn)而為進(jìn)一步推廣預(yù)制裝配式混凝土結(jié)構(gòu)提供有價(jià)值的參考。
[Abstract]:Energy saving, environmental protection and sustainable development put forward new requirements for building technology, improve housing industrialization and modernization level is an important way to achieve green building. From the development experience of housing industrialization, through building system standardization, The integrated construction of technology can not only meet the needs of people for housing, but also improve the comprehensive performance of housing. More importantly, it conforms to the concept of sustainability and is an important way to realize green building and green construction. When the prefabrication rate of residence is 37, 36 water can be saved, garbage will be reduced by 833, material wastage will be reduced by 60, electricity will be saved by more than 31%, and energy conservation will be more than 50%. Therefore, to improve the industrialization and modernization of housing has become the only way for the development of housing in our country. Prefabricated concrete structure has become the development direction of building structure system in the future. According to the precast outer wall as an important part of the prefabricated concrete structure, this paper analyzes and studies the problems of the prefabricated exterior wall of the assembly shear wall structure of Shenyang Metro 路Lishui New City. For the precast wall board and the inside shear wall, the heat preservation filling material is changed into concrete pouring, which makes the precast wall board strengthen the constraint on the whole structure and increase the stiffness, which results in the reduction of the natural vibration cycle of the structure. The SATWE in PKPM is used to calculate the reduction coefficient of natural vibration period, and the MIDAS/Gen finite element software is used to analyze the elastoplastic static model of prefabricated formwork structure. To verify the seismic performance of the main structure under frequent and rare earthquakes. For the use of prefabricated external wall slabs as prefabricated concrete formwork (hereinafter referred to as prefabricated formwork), and in actual construction, the upper and lower teeth are completely separated from each other. Cement mortar is used to smooth the tooth mouth, which can not realize the out-of-plane limit, which results in a complete change in the external loading mode of the external hanging plate. At the same time, due to the lateral pressure of the cast-in-place concrete of the wall, the external hanging plate expands in the out-of-plane direction. The structural safety of the external wall panel is affected. Therefore, using MIDAS/Gen finite element software to analyze the stress of the external wall template in the stage of use and construction, the reinforcement scheme of the external wall board is put forward. Connection is one of the most important parts for fabricated sandwich insulation wall panels. In order to further study the prefabricated exterior wall panels, this paper is based on 3600 脳 3000 (including windowed 1500 脳 1800) prefabricated sandwich wall panels. Using fiber tendons as connectors, the finite element stress analysis is carried out by using ABAQUS calculation model to verify that different forms of fiber reinforced connectors can meet the stress requirements and form a complete technical scheme. Provide technical support for the application of new connectors. Finally, the paper summarizes the research results of this paper, solves the technical problems in practical application of engineering, and provides a valuable reference for the further popularization of prefabricated concrete structures.
