As a novel structure, the integrated building-bridge station has appeared in the high speed railway construction of China, which is of great significant to ensure the seismic safety of the new structure in an earthquake. Meanwhile, the isolation technique which is an important passive control strategy has also been widely used in both buildings and bridges. Based on these, an intensive study of the story isolation technique is carried out in this paper which is to investigate the isolation technique's feasibility and effect on the integrated building-bridge station. Firstly, given the special characteristics of structure and isolation devices which are usually installed on the connection positions between the building and bridge, the numerical model is established considering the dynamic coupling effect. As earthquake ground motion is practically a random process, an accurate and efficient stochastic expression is derived based on the pseudo-excitation method and complex mode technique. Then a rational and effective optimization strategy is proposed to achieve the appropriate setting of the isolation devices. Finally, a numerical example is given to investigate the story isolation technique's application in the integrated building-bridge station by utilizing the stochastic analysis method and optimization strategy proposed in this paper.
