【摘要】：建筑工業(yè)化最初是一些發(fā)達(dá)國(guó)家為了克服傳統(tǒng)建筑生產(chǎn)中存在的耗能高、污染大、施工質(zhì)量差等一系列問題而出現(xiàn)的。近年來,我國(guó)民用建筑工業(yè)化發(fā)展如火如荼,先后出現(xiàn)了大板建筑、框架輕板建筑、大模板建筑等形式,政府也先后出臺(tái)多項(xiàng)政策來保障了建筑工業(yè)化的高速、優(yōu)質(zhì)發(fā)展。然而糧倉(cāng)建筑的工業(yè)化水平依然很低,存在著建設(shè)過程中現(xiàn)場(chǎng)工作量大,可持續(xù)發(fā)展水平低,對(duì)新材料、新技術(shù)的容納程度低,對(duì)環(huán)境的親和性弱,工業(yè)化程度滯后等一系列的問題。密肋復(fù)合板結(jié)構(gòu)作為一種輕質(zhì)、高強(qiáng)、節(jié)能的新型預(yù)制裝配式結(jié)構(gòu),在民用建筑中展現(xiàn)出來了良好的抗震性能、施工適用性強(qiáng)、工業(yè)化程度高等一系列優(yōu)點(diǎn)。密肋復(fù)合板結(jié)構(gòu)在糧倉(cāng)中的適用性及優(yōu)點(diǎn)也已經(jīng)得到了初步的驗(yàn)證。但是把密肋復(fù)合板結(jié)構(gòu)引入到平房倉(cāng)中來,對(duì)整體結(jié)構(gòu)的受力性能尚缺乏系統(tǒng)性的分析。本文的主要研究?jī)?nèi)容如下:對(duì)國(guó)內(nèi)學(xué)者關(guān)于密肋復(fù)合板結(jié)構(gòu)的研究成果進(jìn)行梳理分析,設(shè)計(jì)結(jié)構(gòu)模型試驗(yàn),對(duì)密肋復(fù)合墻板進(jìn)行側(cè)向壓力作用下的破壞性試驗(yàn)。研究分析密肋復(fù)合板結(jié)構(gòu)在側(cè)壓力荷載作用下的受力、破壞形式,試件對(duì)均分布荷載的承載能力及受力機(jī)理。采用大型通用有限元軟件ABAQUS建立了密肋復(fù)合板結(jié)構(gòu)的有限元分析模型,并通過與試驗(yàn)同樣的加載制度進(jìn)行了數(shù)值模擬分析,與試驗(yàn)結(jié)果比對(duì),驗(yàn)證其有效性和合理性。同時(shí),更加直觀而全面的分析了密肋復(fù)合板結(jié)構(gòu)的受力性能。利用通過驗(yàn)證的有限元模型系數(shù),建立相同大小的370mm厚普通磚墻傳統(tǒng)平房倉(cāng)和300mm厚密肋房式倉(cāng)模型,分別進(jìn)行整體受力性能分析,對(duì)比了兩種倉(cāng)型在糧食荷載作用下的內(nèi)力、應(yīng)力、變形等情況,分析表明密肋房式倉(cāng)的抗側(cè)能力和分散傳遞荷載的能力更加顯著。
[Abstract]:The industrialization of construction appeared in some developed countries in order to overcome a series of problems such as high energy consumption, high pollution and poor construction quality. In recent years, the industrialization of civil architecture in our country has developed in full swing, such as large slab building, frame light slab building, large formwork building and so on. The government has also issued many policies to guarantee the high speed and high quality development of construction industrialization. However, the industrialization level of granary building is still very low, there is a heavy workload in the construction process, low level of sustainable development, low capacity for new materials and new technologies, and weak affinity to the environment. The degree of industrialization lags behind a series of problems. As a new type of prefabricated structure with light weight, high strength and energy saving, the multi-ribbed composite plate structure has shown a series of advantages in civil buildings, such as good seismic performance, strong construction applicability, high degree of industrialization and so on. The applicability and advantages of multi-ribbed composite plate structure in granary have also been preliminarily verified. However, the mechanical performance of the whole structure is still lack of systematic analysis when the multi-ribbed composite plate structure is introduced into the bunker. The main contents of this paper are as follows: carding and analyzing the research results of domestic scholars on the structure of multi-ribbed composite panels, designing structural model tests, and carrying out destructive tests on multi-ribbed composite wall panels under lateral pressure. The stress and failure mode of multi-ribbed composite plate structure under lateral pressure are studied and analyzed. The load-bearing capacity and stress mechanism of the specimen to average distributed load are analyzed. The finite element analysis model of multi-ribbed composite plate structure is established by using Abaqus, and the validity and rationality of the model are verified by the numerical simulation of the same loading system as the test results. At the same time, the mechanical performance of multi-ribbed composite plate structure is analyzed more intuitively and comprehensively. By using the verified finite element model coefficient, the traditional warehouse model of 370mm thick brick wall and the model of 300mm thick rib warehouse are established, and the internal forces of the two types under grain load are compared. The analysis of stress and deformation shows that the lateral resistance and the ability of spreading load are more obvious.
