摘要：
Temperature effect on the dynamic performance of structures is a new researching direction in structural dynamics. The paper deduces formulae for temperature effects on the natural frequencies of the beam in specific boundary conditions. The result is validated by finite element method and the experiment. An artificial earthquake record with the Kanai-Tajimi model and trigonometric series superposition method is generated. The artificial earthquake record is used to analyze seismic performance of the Subway station structure. When temperature changes 20 degrees C, the stress of structure changes about 9.6%, while stress amplitude reaches 0.24MPa.
