Seismic Analysis of Separated Platform Subway Station Structure

Abstract:

Article Preview

As separated platform subway station structures are close to the bridge piles, its seismic performance need to be analyzed. An artificial earthquake record is used to analyze seismic performance of the subway station structure. The artificial earthquake record with the Kanai–Tajimi model and trigonometric series superprosition method is generated. It is shown that the influences of the stresses of arch springing and basement are significant under horizontal direction earthquake. Under horizontal direction earthquake, the horizontal stresses of arch springing and basement are 1.46 and 1.61 times than the original stresses and their vertical stresses are 1.34 and 1.59 times than the original stresses. It is shown that the influences of the horizontal stress of soleplate and the vertical stresses of arch springing and basement are significant under vertical direction earthquake. Under vertical direction earthquake, the horizontal stresse of soleplate is 3.30 times than the original stress, while vertical stresses of arch springing and basement are 2.78 and 2.72 times than the original stresses.
