［摘要］襄陽(yáng)東津站站房長(zhǎng)度超過300m，屬于超長(zhǎng)結(jié)構(gòu)。采用時(shí)程分析方法，利用ABAQUS軟件對(duì)結(jié)構(gòu)進(jìn)行小震彈性和大震彈塑性多點(diǎn)激勵(lì)與一致激勵(lì)的對(duì)比分析，考察行波效應(yīng)對(duì)結(jié)構(gòu)的影響。分析結(jié)果表明，小震彈性階段，考慮行波效應(yīng)后結(jié)構(gòu)角柱、邊柱及斜撐內(nèi)力有所加大；大震彈塑性分析階段，考慮行波效應(yīng)后結(jié)構(gòu)損傷程度未見明顯加重，僅個(gè)別構(gòu)件損傷略微加大。分析結(jié)果為結(jié)構(gòu)設(shè)計(jì)中考慮行波效應(yīng)的影響提供了依據(jù)。

Abstract:The length of station building of Xiangyang-Dongjin Railway Station is more than 300m, which belongs to the super-long structure. Using time-history analysis method and ABAQUS software, a comparative analysis was made of elastic and elastoplastic multi-support seismic excitation and uniform excitation under frequent and rare earthquakes, and the influence of traveling wave effect on the structure was investigated. The results show that in the elastic stage under the frequent earthquake, the internal forces of corner columns, side columns and diagonal braces increase after considering the traveling wave effect; in the elastic-plastic analysis stage under the rare earthquake, the damage degree of the structure does not increase significantly after considering the traveling wave effect, but only the damage of individual components increases slightly. The analysis results provide a basis for considering the effect of traveling wave in the structural design.
