【摘要】：世界上墻體建材的發(fā)展已經(jīng)向輕質(zhì)復合材料、合成材料的方向進軍。在建筑結(jié)構(gòu)和建筑功能材料上形成了一個比較完善的新型建材體系。我國現(xiàn)如今的建材能耗遠高于其他國家,比如先前有部分內(nèi)隔墻采用粘土燒結(jié)的磚墻,十分浪費資源,完全不符合國家倡導的綠色環(huán)�？沙掷m(xù)發(fā)展的號召。本文對目前國內(nèi)外建筑的節(jié)能材料和形式進行了概括分析,并在現(xiàn)有的鋼框架—墻板復合體系的基礎上,對一種薄壁型鋼—混凝土復合保溫承重墻板進行了研究。薄壁型鋼—混凝土復合保溫承重墻板,由薄壁型鋼—混凝土作為主要承重骨架,該承重體系在薄壁型鋼骨架外面澆筑混凝土,使鋼框架與混凝土協(xié)同受力,共同承擔豎向荷載,然后在承重骨架里面用保溫砂漿作為填充材料,本墻板不僅節(jié)能環(huán)保,而且受力性能好。為了研究本墻板在豎向荷載下的力學性能,做了6塊墻板,用以軸壓和偏壓試驗。偏壓試驗主要分為偏心距20mm和偏心距40mm兩種方案。每種試驗需對2塊墻板加載。研究在不同的荷載下,墻板的破壞現(xiàn)象、極限承載力和位移等力學性能。運用ABAQUS有限元軟件對墻體模型進行模擬分析,分別模擬墻體在軸壓和偏壓狀態(tài)下的破壞過程及極限承載力,并與試驗結(jié)果對比,以驗證有限元分析的可靠性。通過ABAQUS有限元軟件來模擬足尺墻板在豎向荷載下的受力性能,針對影響墻板受力性能的主要參數(shù),比如:高寬比、高厚比等,通過改變這些參數(shù),設計不同的足尺墻體模型,來模擬真實墻板的豎向受力性能,最后通過荷載—位移曲線、應力—應變曲線等,對保溫復合墻板的承載力進行研究。論文的研究成果對本復合保溫承重墻板的設計與應用提供了重要的理論依據(jù)及實用價值。
[Abstract]:The development of wall building materials in the world has moved towards the direction of lightweight composite materials and synthetic materials. In the building structure and building function materials form a relatively perfect new building materials system. Nowadays, the energy consumption of building materials in our country is much higher than that in other countries. For example, some inner partition walls used clay sintered brick wall, which is a waste of resources, which is completely inconsistent with the call of green environmental protection and sustainable development advocated by our country. In this paper, the energy saving materials and forms of buildings at home and abroad are analyzed, and on the basis of the existing steel frame-wall panel composite system, a kind of thin-walled steel-concrete composite heat preservation bearing wall slab is studied. Thin-walled steel-concrete composite heat preservation and load-bearing wall slab is composed of thin-walled steel-concrete as the main load-bearing skeleton. The load-bearing system places concrete outside the thin-walled steel skeleton to make the steel frame and concrete work together to bear the vertical load. Then heat preservation mortar is used as filling material in the bearing skeleton. The wall board not only saves energy and environmental protection, but also has good mechanical performance. In order to study the mechanical properties of the wallboard under vertical load, six wallboards were made for axial compression and biasing tests. The bias test is mainly divided into two schemes: eccentric 20mm and eccentric 40mm. Each test requires loading of 2 walls. The failure phenomenon, ultimate bearing capacity and displacement of wall panels under different loads are studied. The failure process and ultimate bearing capacity of the wall under axial compression and eccentric compression were simulated by using ABAQUS finite element software, and the results were compared with the experimental results to verify the reliability of the finite element analysis. In this paper, the finite element software ABAQUS is used to simulate the mechanical behavior of full-scale wall panels under vertical load. According to the main parameters, such as aspect ratio, ratio of height to thickness and so on, different full-scale wall models are designed by changing these parameters. Finally, through load-displacement curve, stress-strain curve and so on, the bearing capacity of thermal insulation composite wallboard is studied. The research results of this paper provide important theoretical basis and practical value for the design and application of the composite insulation bearing wall.
