【摘要】：鋼梁-輕骨料混凝土柱組合結(jié)構(gòu)結(jié)合了兩種材料同樣輕質(zhì)高強(qiáng)的特點(diǎn),即能從經(jīng)濟(jì)方面又能從合理角度充分發(fā)揮出鋼材和輕骨料混凝土的力學(xué)性能。近些年來(lái),在發(fā)達(dá)國(guó)家例如美國(guó)、日本等受到越來(lái)越廣泛的應(yīng)用。鋼梁-鋼筋混凝土柱結(jié)構(gòu)即使對(duì)純鋼結(jié)構(gòu)和鋼筋混凝土結(jié)構(gòu)的一種繼承同時(shí)又是對(duì)這兩種結(jié)構(gòu)的一種發(fā)展。本論文主要是通過(guò)有限元軟件ABAQUS進(jìn)行一系列分析。文章一共分5個(gè)章節(jié),第一章為緒論。第二章主要介紹有限元建模方法、注意事項(xiàng)以及本構(gòu)模型的選擇。第三章在章節(jié)開(kāi)頭對(duì)已完成的試驗(yàn)的現(xiàn)象及結(jié)果進(jìn)行了簡(jiǎn)單闡述,并建立與試驗(yàn)相同的有限元模型驗(yàn)證了模型的可行性。第四章主要建立了兩類(lèi)節(jié)點(diǎn)的有限元模型并采用單調(diào)荷載的加載方式。并對(duì)兩者的有限元結(jié)果進(jìn)行對(duì)比,驗(yàn)證新型節(jié)點(diǎn)的承載力是否有所提高。第五章一方面對(duì)比兩類(lèi)節(jié)點(diǎn)在地震作用下的抗震能力,驗(yàn)證新型節(jié)點(diǎn)的抗震性能是否優(yōu)于原有節(jié)點(diǎn)。另一方面通過(guò)有限元模擬,分析了不同軸壓比對(duì)新型節(jié)點(diǎn)抗震性能的影響。本文主要根據(jù)鋼梁-鋼筋混凝土柱結(jié)構(gòu)的已有節(jié)點(diǎn)連接試驗(yàn),驗(yàn)證有限元分析的可行性以及通過(guò)有限元軟件分析鋼梁-輕骨料混凝土柱節(jié)點(diǎn)的受力性能。并根據(jù)T型鋼的節(jié)點(diǎn)連接方式提出一種不等邊角鋼連接的新型節(jié)點(diǎn)連接方式。用有限元軟件ABAQUS建立單調(diào)荷載下以及循環(huán)荷載下兩種模型,并與原有節(jié)點(diǎn)在這兩種加載方式下的有限元模型計(jì)算結(jié)果進(jìn)行對(duì)比,分析新型節(jié)點(diǎn)鋼梁-輕骨料混凝土柱結(jié)構(gòu)中可行性。
[Abstract]:The composite structure of steel beam-light aggregate concrete column combines the characteristics of two kinds of materials with the same light weight and high strength, that is, it can give full play to the mechanical properties of steel and lightweight aggregate concrete from the aspect of economy as well as from a reasonable point of view. In recent years, in developed countries such as the United States, Japan and so on are more and more widely used. The steel beam-reinforced concrete column structure not only inherits the pure steel structure and the reinforced concrete structure, but also develops the two kinds of structures. This paper mainly carries on a series of analysis through finite element software ABAQUS. The article is divided into five chapters, the first chapter is an introduction. The second chapter mainly introduces the finite element modeling method, matters needing attention and the choice of constitutive model. At the beginning of chapter three, the phenomena and results of the completed experiments are briefly described, and the same finite element model is established to verify the feasibility of the model. In chapter 4, the finite element model of two kinds of nodes is established and the loading mode of monotone load is adopted. The finite element results are compared to verify whether the bearing capacity of the new joints has been improved. The fifth chapter compares the seismic capacity of the two types of joints under earthquake and verifies whether the seismic performance of the new joints is better than that of the original joints. On the other hand, through finite element simulation, the influence of different axial compression ratio on seismic performance of new joints is analyzed. In this paper, the feasibility of finite element analysis and the mechanical behavior of steel beam-light aggregate concrete column joints are analyzed by means of the existing joint connection test of steel beam-reinforced concrete column structure. According to the joint connection mode of T section steel, a new joint connection mode with unequal edge angle steel connection is proposed. The finite element software ABAQUS is used to establish two models under monotone load and cyclic load, and the results are compared with the results of finite element model under these two loading modes. The feasibility of a new type of steel beam-light aggregate concrete column structure is analyzed.
