【摘要】：漿錨連接裝配式剪力墻結(jié)構(gòu)體系以其施工速度快、建造質(zhì)量高及可持續(xù)發(fā)展等優(yōu)點越來越受到業(yè)主和設(shè)計人員的關(guān)注。金屬波紋管成孔漿錨連接裝配式剪力墻結(jié)構(gòu)體系預(yù)制構(gòu)件包括：鋼筋漿錨裝配式剪力墻剪力墻、預(yù)制疊合板、預(yù)制疊合梁。預(yù)制豎向構(gòu)件通過預(yù)留金屬波紋管成孔后灌漿養(yǎng)護實現(xiàn)鋼筋漿錨連接,預(yù)制疊合構(gòu)件通過后澆鋼筋混凝土實現(xiàn)結(jié)構(gòu)整體連接。由于我國地震區(qū)域分布廣泛,裝配式剪力墻結(jié)構(gòu)技術(shù)在我國的大規(guī)模應(yīng)用需滿足抗震設(shè)防的要求。本文以南通市某裝配式剪力墻高層住宅結(jié)構(gòu)試點工程為背景,取其受力最大部位進行裝配式剪力墻空間結(jié)構(gòu)模型的抗震性能試驗研究,主要完成的工作和相關(guān)成果如下：(1)通過對改進型金屬波紋管成孔漿錨連接裝配式剪力墻空間結(jié)構(gòu)模型進行低周反復(fù)荷載試驗,對其抗震性能進行深入的研究。觀測試件在低周反復(fù)荷載下開裂、屈服、破壞全過程及破壞形態(tài)等,分析構(gòu)件的裂縫發(fā)展、滯回性能、強度退化、剛度退化、延性以及耗能能力,同時分析裝配式剪力墻結(jié)構(gòu)在水平荷載下應(yīng)變分布情況等。試驗結(jié)果表明：改進型金屬波紋管成孔漿錨連接裝配式剪力墻結(jié)構(gòu)具有較好的抗震性能；(2)采用非線性有限元軟件ABAQUS對試驗構(gòu)件進行模擬分析,對改進型金屬波紋管成孔漿錨連接裝配式剪力墻空間結(jié)構(gòu)在整個受力過程中的混凝土、鋼筋的應(yīng)力、應(yīng)變以及裂縫的形成和發(fā)展情況進行分析,了解其在水平荷載作用下受力性能；(3)通過試驗實測結(jié)果與有限元數(shù)值計算結(jié)果進行對比,表明有限元模擬的計算承載力與試驗實測承載力較為接近；有限元模型中剪力墻混凝土受拉損傷準確揭示構(gòu)件裂縫開裂位置和裂縫分布規(guī)律,與試驗實測結(jié)果符合較好。最后,在總結(jié)全文的基礎(chǔ)上,對裝配式剪力墻結(jié)構(gòu)的優(yōu)化及后續(xù)研究提出一些建議。
[Abstract]:With the advantages of high construction speed, high construction quality and sustainable development, grouting anchor connection assembly shear wall structure system has been paid more and more attention by owners and designers. The prefabricated components include: reinforced mortar anchor assembly shear wall shear wall, prefabricated laminated board and prefabricated laminated beam. Prefabricated vertical members are connected by grouting after retaining metal bellows to form holes, and prefabricated composite members are connected by post-pouring reinforced concrete. Due to the wide distribution of earthquake in China, the large-scale application of prefabricated shear wall structure technology in China needs to meet the requirements of seismic fortification. Based on the experimental project of a prefabricated shear wall high-rise residential structure in Nantong City, the seismic behavior of the spatial structure model of the prefabricated shear wall is studied with the maximum force. The main work and related results are as follows: 1) the seismic behavior of the modified metal corrugated pipe is studied by the low-cycle repeated load test on the model of the modified metal corrugated pipe. The cracking, yield, failure process and failure pattern of the specimens under low cyclic cyclic loading were observed. The crack development, hysteretic properties, strength degradation, stiffness degradation, ductility and energy dissipation capacity of the members were analyzed. At the same time, the strain distribution of prefabricated shear wall structure under horizontal load is analyzed. The test results show that the modified metal bellows are of good seismic performance. The nonlinear finite element software ABAQUS is used to simulate and analyze the test members. In this paper, the stress, strain, crack formation and development of reinforced concrete, reinforced bar, and the formation and development of cracks of the modified metal corrugated pipe are analyzed in the course of the whole stress process of the assembled shear wall space structure, which is connected with the prefabricated shear wall space structure by the hole grouting anchor of the metal bellows. Through comparing the experimental results with the results of finite element numerical calculation, it is shown that the calculated bearing capacity of finite element simulation is close to that of test. The tensile damage of shear wall concrete in the finite element model accurately reveals the crack position and crack distribution of the member, which is in good agreement with the experimental results. Finally, on the basis of summing up the whole paper, some suggestions are put forward for the optimization and follow-up study of assembled shear wall structure.
