武汉火车站中央站房整体模型振动台试验研究

Shaking Table Test Study on an Integral Model of Central Station Building of Wuhan Railway Station

武汉站是铁路武汉枢纽最主要的客运站,分为中央站房结构和雨棚结构,中央站房是由楼面结构和屋面结构组体成抗大震跨性空能间,并结对构结。构本的文设介计绍提了出1了颐5相0缩应尺建比议例。的试整验体结模果型表振明动,武台汉试火验车,研站究结了构模满型足结"三构个的水动力准特"的性抗,评震价设了防该目结标构,同体时系结的构整在抗震设防方面的安全储备是足够的。

Wuhan railway station is the uppermost railway passenger station of Wuhan railway terminal consisting of central station building and station canopy.The central station building is a long-span spatial structure composed of floor structures and roof structures.In this paper,simulating seismic shaking table test study on an 1：30 scaled model of this structure is introduced,the dynamic characteristics is analyzed,the seismic behaviors are evaluated,and some design suggestions are put forward.The test results show that the central station building of Wuhan railway station can achieve the three level earthquake fortification target,and the structure has enough emergency capacity under the fortification intensity of earthquake action.
