Abstract


With the large-scale development of China's high-speed rail and urban rail transit station bridge one \But this new structural system of the power transmission path is complex and based on the ability of seismic design ideology is not consistent, the lack of seismic design specifications, as well as the yield mechanism and failure mode is also a lack of in-depth analysis, very necessary to carry out its seismic performance system research. In this paper carried out the research work of the following aspects: one of incremental dynamic analysis (IDA) applied to the seismic performance analysis of complex structures and Modal Pushover Analysis (MPA) detail introduced its theoretical basis, and pointed out its strengths and weaknesses and the scope of application. Second, to conform to the station bridge one \The study showed that: Overall, good seismic performance of the station structure, able to meet the requirements under the earthquake. With the increase of PGA longitudinal main beams node and the secondary beam node is the first to enter the plastic after, reinforced concrete columns and circular steel tubular column turn into plastic CFRT columns; PGA is 1.4g, a small amount into a non-linear sexual status. Indicate that the node is the weak link of the seismic design of such stations. Third, the complex roof truss the station bridge one \Studies have shown that the quality of the roofing layer station seismic performance there, when the roof layer quality accounted for 4% of the total mass of the structure, the roof layer of the track beam plastic most significant, the other proportion under the conditions of their impact was parabolic reduced. 7 degrees and 8 degrees fortification intensity, the structure of the top-level displacement increase with the quality of the roofing layer decreases monotonously; fortification intensity of 9 degrees, the capacity spectrum in addition to, and not in uniform increase performance point displacement with the quality of the roofing layer reflects the high intensity of the next top-level amplification of the plastic state of deformation. Fourth, using the the MPA method of roofing layer stiffness values ??of the seismic performance of the station bridge one \The study showed that the roof layer stiffness affect the tiny station seismic performance, when the roof stiffness accounted for 4% of the overall stiffness of the structure, roofing layers adverse effect on the track beam plastic, causing it to accelerate into the plastic state, the need to optimize the proportion of the stiffness of the structure of the different layers.
