【摘要】:目前,隨著我國(guó)城鎮(zhèn)化進(jìn)程的不斷深入,范圍不斷擴(kuò)大,全國(guó)新建住宅需求量也在不斷增加。顯然,這種情況在未來(lái)的幾十年內(nèi)不會(huì)發(fā)生改變。我國(guó)城市人口密度較高,城市內(nèi)的土地資源緊張,短時(shí)間內(nèi)難以模仿歐美發(fā)達(dá)國(guó)家的城鎮(zhèn)化模式:重點(diǎn)發(fā)展少數(shù)超大型城市,同時(shí)建設(shè)更多宜居的中小型城鎮(zhèn),控制城市人口,以建設(shè)多層住宅或者別墅群來(lái)滿足居住需求。我國(guó)現(xiàn)階段城鎮(zhèn)化的發(fā)展模式仍是擴(kuò)大城市規(guī)模,吸納新城市人。如何滿足日益涌入城市的人們的住房需求與最大限度的利用有限的城鎮(zhèn)土地資源是一個(gè)亟待解決的問(wèn)題。在這種趨勢(shì)之下,加速建設(shè)高層住宅群應(yīng)將成為未來(lái)一段時(shí)間中國(guó)大多數(shù)城市的發(fā)展的一種合理選擇。從建筑結(jié)構(gòu)研究的角度來(lái)說(shuō),開(kāi)發(fā)出更加有效利用資源,以低污染、低成本建設(shè)質(zhì)量更好的高層住宅建筑體系是解決這一矛盾的一種途徑。 本文所研究的裝配式型鋼剪力墻組合結(jié)構(gòu)就是針對(duì)高層住宅建筑所提出的一種結(jié)構(gòu)體系,該結(jié)構(gòu)體系由北京市建筑設(shè)計(jì)研究院有限公司提出。本文主要介紹三個(gè)相關(guān)試驗(yàn)的研究?jī)?nèi)容。全文共分為六章,包括: (1)緒論。闡述我國(guó)住宅產(chǎn)業(yè)化發(fā)展現(xiàn)狀,說(shuō)明開(kāi)發(fā)裝配式結(jié)構(gòu)住宅的必要性。介紹了國(guó)內(nèi)外關(guān)于裝配式結(jié)構(gòu),尤其是裝配式剪力墻結(jié)構(gòu)的研究情況。最后,列出本文研究的主要內(nèi)容。 (2)新型裝配整體式墻體抗震性能試驗(yàn)。本試驗(yàn)包含兩組墻片,,第一組試驗(yàn)考察了墻片豎縫位置干式連接方式的抗震性能,而第二組試驗(yàn)檢驗(yàn)型鋼邊緣約束構(gòu)件、高強(qiáng)度灌漿料后澆帶及后澆帶內(nèi)型鋼抗剪鍵的連接性能。 (3)裝配整體式型鋼剪力墻組合結(jié)構(gòu)擬靜力試驗(yàn)。通過(guò)介紹試驗(yàn)?zāi)P偷脑O(shè)計(jì)、制作、組裝及擬靜力試驗(yàn)全過(guò)程,對(duì)該結(jié)構(gòu)體系的施工工藝進(jìn)行了歸納,對(duì)結(jié)構(gòu)的強(qiáng)度、剛度、延性、耗能等性能指標(biāo)進(jìn)行了考察和研究。 (4)采用螺栓連接的預(yù)制鋼骨剪力墻擬靜力試驗(yàn)。為考察墻片水平縫位置螺栓連接節(jié)點(diǎn)的抗震性能設(shè)計(jì)了四組擬靜力試驗(yàn),分別檢驗(yàn)預(yù)埋螺栓連接的預(yù)制剪力墻片抗彎、抗剪性能,得出了試驗(yàn)體的強(qiáng)度、剛度、延性和耗能性能參數(shù)。 (5)結(jié)論與展望。歸納總結(jié)試驗(yàn)過(guò)程中的經(jīng)驗(yàn)與不足,提出一些建議,并為后續(xù)的研究提供一點(diǎn)思路。
[Abstract]:At present, with the development of urbanization in China, the demand for new housing is increasing. Clearly, this will not change for decades to come. Because of the high population density and the shortage of land resources in cities, it is difficult to imitate the urbanization pattern of developed countries in Europe and the United States in a short period of time. To build multi-storey houses or villas to meet the housing needs. At present, the development mode of urbanization in China is still to expand the scale of the city and absorb the new city people. How to meet the housing needs and maximize the utilization of limited urban land resources is an urgent problem to be solved. Under this trend, speeding up the construction of high-rise residential clusters should be a reasonable choice for the development of most cities in China for some time to come. From the point of view of building structure research, it is a way to solve this contradiction to develop a high-rise residential building system with low pollution and low cost, which can make use of resources more effectively and build a better quality high-rise residential building system with low pollution and low cost. The assembled steel shear wall composite structure studied in this paper is a kind of structural system for high-rise residential buildings, which was proposed by Beijing Architectural Design and Research Institute Co., Ltd. This paper mainly introduces the research contents of three related experiments. The full text is divided into six chapters, including: (1) introduction. This paper expounds the present situation of housing industrialization in China, and explains the necessity of developing assembled structure housing. This paper introduces the research situation of assembled structure, especially the assembled shear wall structure at home and abroad. Finally, the main contents of this paper are listed. (2) the seismic performance test of the new assembled integral wall. This experiment consists of two groups of walls. The first group of tests examined the seismic performance of the dry connection at the vertical joint position of the walls, while the second group tested and tested the edge-constrained members of the section steel. High strength grouting material post-pouring belt and post-cast steel shear bond connection performance. (3) pseudo-static test of assembled integral steel shear wall composite structure. Through the introduction of the design, fabrication, assembly and quasi-static test of the test model, the construction technology of the structural system is summarized, and the strength, stiffness, ductility and energy dissipation of the structure are investigated and studied. (4) pseudo-static test of prefabricated steel shear wall with bolted connection. Four groups of quasi-static tests were designed to investigate the seismic behavior of bolt-joint joints in horizontal joints of wall pieces. The bending and shear properties of prefabricated shear walls connected with pre-embedded bolts were tested respectively, and the strength and stiffness of the test body were obtained. Ductility and energy dissipation performance parameters. (5) conclusion and prospect. This paper summarizes the experience and deficiency in the process of experiment, puts forward some suggestions, and provides some ideas for the follow-up research.
