混凝土空心板推擠成型機In this thesis, four types of steel beam - rectangular cfst column connections, including normal welded flange plate ( wfp ) connection, bolted flange plate ( bfp ) connection, stiffened end plate ( sep ) connection and double split - tee plate ( dst ) connection, were designed based on the configuration of steel frame connection. total 8 models, 2 models of each kind of connections were tested under low - reversed cyclic loading at the end of cfst columns. the relationships between force and displacement at the end of columns, the relationships between the moment and rotation of the joints, degradations of strength and stiffness, ductility, failure mechanism and failure characteristics of these four connections under different axial - compression ratios were presented
本文借鑒鋼框架節點構造，設計了四種類型矩形鋼管混凝土柱與鋼梁連接節點，包括常規栓焊（ wfp ）節點、翼緣全螺栓連接（ bfp ）節點、雙t板連接（ dst ）節點以及加勁端板連接（ sep ）節點，進行了四類節點8個模型試件在柱端低周反復荷載作用下的抗震性能試驗研究，比較了不同軸壓比下節點的滯回性能、強度與剛度退化、延性、破壞機理與破壞特徵，主要結論有： 1 、節點的位移滯回曲線與轉角滯回曲線為塊型分佈，沒有或略有捏攏現象，耗能能力強； 2 、軸壓比對節點滯回曲線有顯著影響，全部節點都有顯著的剛度退化； 3 、位移與轉角骨架曲線在峰值荷載後有較長的水平或下降段，具有良好的延性性能； 4 、從整體抗震性能上看，翼緣全螺栓連接節點、雙t板連接與加勁端板連接節點都優于常規栓焊節點，可在實際工程中加以推廣。This paper focuses on the research of the stress mechanism of the ribbed shell structure in statics, dynamics and under the explosive load on the basis of the engineering practice of cave depot of single aircraft. in this paper, according to the classical shell theories, the basic differential equilibrium of the ribbed shell structure and the finite element analysis of 3d rippled plate are established, in which the function of annular ribs reinforcement bars and 3d ripped steel plates are distributed in the range of the steel, and the functions along the longitude direction of tension, bending, and torsion are neglected ; applied with dynamic analytical theory, the dynamic model of ribbed shell structure and the analytical theory model of elastic - plastic are set up ; the triangle series method is used to solve the displacement and stress under the distributed load and the concentrated load of the ribbed shell structure
本文以軍用機場地面單機掩蔽庫工程建設為工程背景，首次對內襯三維波紋鋼板混凝土拱型復合結構的受力機理進行了靜力、動力和爆炸荷載的分析研究。根據將橫肋、鋼筋及三維波紋鋼板的作用均勻分佈在殼體范圍內的情況，忽略橫肋、鋼筋及三維波紋鋼板沿殼體母線方向的抗拉、抗彎及其抗扭作用，首次推導出了內襯三維波紋鋼板混凝土殼體的微分平衡方程，建立了有限元計算模型，並採用三角函數法，求解了三維波紋鋼板混凝土拱型復合結構在分佈荷載和集中荷載作用下的位移響應和應力響應，並與普通殼體進行了比較。Testing earth - moving machinery - method for determination of volumetric rating of crawler and wheel tractor dozer blades
