［摘要］對1榀由鋼框架和預(yù)制混凝土抗側(cè)力墻組成的足尺試件進(jìn)行了豎向加載試驗(yàn)，考察該裝配式結(jié)構(gòu)在施工和使用階段豎向荷載的分配關(guān)系以及框架梁撓度的變化規(guī)律。在試驗(yàn)研究基礎(chǔ)上，采用ABAQUS有限元軟件建立與驗(yàn)證試驗(yàn)?zāi)Ｐ?，并以?shí)際工程為背景，建立6層和12層單跨鋼框架預(yù)制混凝土抗側(cè)力墻裝配式結(jié)構(gòu)模型，模擬分析了多高層結(jié)構(gòu)在三種施工方案下的豎向受力性能以及框架梁的變形規(guī)律。研究結(jié)果表明：采用先逐層安裝預(yù)制構(gòu)件，后逐層終擰高強(qiáng)螺栓的施工順序，能夠保證抗側(cè)力墻體僅承擔(dān)使用階段的豎向活荷載，大幅度降低了墻體的軸壓比。在使用階段，隨著樓層層數(shù)的增多，框架柱豎向荷載分擔(dān)率升高，而抗側(cè)力墻體豎向荷載分擔(dān)率降低，兩者之間的差值逐漸增大。

Abstract: In order to investigate the vertical load distribution relationship and frame beams deflection variation of the fabricated structure during the construction and use phase, a fullscale specimen composed of steel frame and prefabricated concrete lateral resistance wall was tested under the vertical load. On the basis of the experimental research, ABAQUS finite element software was used to establish and verify the test model. According to a practical engineering background, six-story and twelve-story steel frame-prefabricated concrete lateral resistance wall fabricated structure models with single span were established, and simulation analysis of the vertical mechanical behavior and beams deformation law on multi-storey and high-rise structure under three kinds of construction schemes was carried out. The results show that the construction sequence of firstly installing prefabricated layer by layer and then finally screwing high-strength bolts step by step can guarantee the lateral resistance wall to bear only vertical live load in the use phase, thereby the wall axial compression ratio is greatly reduced. In the use phase, with the increase of the number of floors, vertical load sharing ratio of the frame columns raises while vertical load sharing ratio of the lateral resistance wall reduces, and the difference between them increases gradually.
