【摘要】：隨著對結(jié)構(gòu)空間和跨度的要求越來越高,鋼管結(jié)構(gòu)因其具有優(yōu)美的外觀、合理的受力特點以及優(yōu)越的經(jīng)濟性,在我國得到快速發(fā)展,尤其是空間鋼管桁架及鋼管剛架均是具有良好承載能力和穩(wěn)定性能的結(jié)構(gòu)形式,因此被廣泛的應用在現(xiàn)代工業(yè)廠房、物流倉庫、航站樓、體育館、展覽館、車站及各種公用建筑中。本文以鋁礦堆場防雨棚的結(jié)構(gòu)設(shè)計為背景,承重結(jié)構(gòu)采用鋼管剛架,剛架梁、柱均采用三角形斷面的空間立體桁架形式。利用結(jié)構(gòu)分析軟件PKPM和大型通用有限元分析軟件ANSYS分別對結(jié)構(gòu)進行了內(nèi)力分析及鑄鋼件節(jié)點承載力分析,具體作了以下幾方面的工作:(1)提出了管桁結(jié)構(gòu)的設(shè)計原則和理論依據(jù)。(2)采用PKPM軟件,建立了鋼管剛架結(jié)構(gòu)的三維模型,并對其進行了詳細的內(nèi)力分析。(3)利用有限元分析軟件ANSYS,建立了鋼管剛架梁、柱桁架相連的鑄鋼件節(jié)點模型。分析了鑄鋼件各個位置的應力狀態(tài),確定鑄鋼件承載力。
[Abstract]:With the increasing demands on the space and span of the structure, the steel pipe structure has been developed rapidly in our country because of its beautiful appearance, reasonable stress characteristics and superior economy. Especially, space steel pipe truss and steel pipe rigid frame are all structural forms with good bearing capacity and stable performance, so they are widely used in modern industrial workshops, logistics warehouses, terminal buildings, gymnasiums, exhibition halls, etc. Stations and various public buildings. In this paper, the structure design of rainproof shed of aluminum mine yard is taken as the background. The load-bearing structure adopts the form of steel pipe rigid frame, rigid frame beam and column, all of which adopt the space three-dimensional truss form of triangle section. The internal force of the structure and the bearing capacity of cast steel joint are analyzed by using the structural analysis software PKPM and the large general finite element analysis software ANSYS respectively. The main works are as follows: (1) the design principle and theoretical basis of pipe truss structure are put forward. (2) the three-dimensional model of steel pipe frame structure is established by using PKPM software. The internal force is analyzed in detail. (3) using the finite element analysis software ANSYS, the model of steel castings joint connected with steel pipe rigid frame beam and column truss is established. The stress state of steel castings at each position is analyzed and the bearing capacity of steel castings is determined.
