［摘要］為充分考察北京大興國(guó)際南航基地1號(hào)機(jī)庫(kù)大廳結(jié)構(gòu)抗震性能,采用ABAQUS6.11對(duì)結(jié)構(gòu)進(jìn)行彈性時(shí)程分析和彈塑性時(shí)程分析，分析中采用ABAQUS提供的材料本構(gòu)模型和用戶自定義材料本構(gòu)模型，計(jì)算了小震和大震作用下機(jī)庫(kù)大廳的響應(yīng)。計(jì)算結(jié)果表明:小震和大震作用下，機(jī)庫(kù)大廳的柱頂最大位移角均小于規(guī)范限值。網(wǎng)架整體保持彈性，局部與柱頂相連部分有輕微屈曲；工字形雙肢格構(gòu)柱保持彈性，多肢格構(gòu)式鋼管混凝土柱的柱底有輕微屈服；格構(gòu)柱柱間防屈曲支撐有輕微屈服，大門角柱普通支撐屈曲失穩(wěn)。多肢格構(gòu)式鋼管混凝土柱和大門中柱的混凝土歷史最大壓應(yīng)變均小于峰值應(yīng)變。由于結(jié)構(gòu)X方向長(zhǎng)度較長(zhǎng)，在計(jì)算的過(guò)程中，考慮了行波效應(yīng)對(duì)結(jié)構(gòu)的影響。大震作用下，考慮行波效應(yīng)后，整體結(jié)構(gòu)最大柱頂位移角有所增加，但依然滿足規(guī)范限值。

Abstract:In order to fully investigate the seismic performance of the NO.1 hangar hall of China Southern Airlines base in Beijing Daxing International Airport, the elastic time-history analysis and elasto-plastic time-history analysis of the structure were carried out by ABAQUS 6.11, and the response of hangar hall under small earthquakes and rare earthquakes was calculated. The material constitutive model provided by ABAQUS and user-defined material constitutive model were used in the analysis. The results show that the maximum story drift angle of the column top of hangar hall is less than the limiting value given in the code under small earthquakes and rare earthquake. The space truss remains elastic as a whole, and the part connected to the top of the column is slightly buckled; the  I-shaped double-leg lattice column remains elastic. The column bottom of the multi-leg lattice concrete-filled steel tube column yielded slightly; the BRB between the lattice column columns yielded slightly, and the gate corner column ordinary support buckled instability. The maximum historical compressive strains of concrete in the multi-leg lattice concrete-filled steel tube column and the central column of the gate are less than the peak strain. Because the span in X direction of structure is so large, the traveling wave effect on the structure is also considered in the calculation process. Under the action of a rare earthquake, considering the traveling wave effect, the maximum story drift angle of the overall structure increases, but it still can meet the limiting value of code.
