［摘要］C形柱是北京大興國(guó)際機(jī)場(chǎng)航站樓結(jié)構(gòu)的關(guān)鍵構(gòu)件，航站樓中心區(qū)主要靠8個(gè)沿中線呈東西對(duì)稱分布的C形柱支承。為考察C形柱在豎向及水平荷載下的受力和變形性能，采用ABAQUS 6-10有限元軟件對(duì)其進(jìn)行豎向及水平極限承載力分析。考慮材料非線性和幾何非線性，當(dāng)材料達(dá)到極限應(yīng)變時(shí)，桿件失效退出工作，桿件初始缺陷按桿件長(zhǎng)度的1/350施加。結(jié)果表明：在大多數(shù)情況下，支撐筒破壞晚于C形柱，在C形柱達(dá)到極限承載力后，支撐筒作為二道防線繼續(xù)承擔(dān)抗側(cè)作用；大震下所有C形柱底部剪力均在承載力的彈性階段，滿足大震不屈服的性能要求。

Abstract:C-shaped column is the key component of the structure of Beijing Daxing International Airport terminal building. The central area of the terminal building is mainly supported by eight C-shaped columns symmetrically distributed along the central line. In order to investigate the mechanical and deformation properties of C-shaped columns under vertical and horizontal loads, ABAQUS 6-10 finite element software was used to analyze the vertical and horizontal ultimate bearing capacity of C-shaped columns. Considering material nonlinearity and geometric nonlinearity, when the material reached the limit strain, the member failed to work, and the initial defect of the member was applied according to 1/350 of the length of the member. The results show that in most cases, the failure of the supporting cylinder is later than that of the C-shaped column. After the ultimate bearing capacity of the C-shaped column is reached, the supporting cylinder, as the second line of seismic defense, continues to bear the lateral resistance. Under rare earthquakes, all the shear forces at the bottom of the C-shaped column are in the elastic section of the bearing capacity, which meets the performance requirements of the non-yielding under rare earthquakes.

Keywords:Beijing Daxing International Airport terminal building; C-shaped column; seismic performance; finite element analysis
