Vibration mitigation of a transit-oriented development building based on periodic theory

Vibration mitigation is a knotty problem in the transit-oriented development (TOD) pattern. In TOD pattern, buildings such as hotels are usually very close to large transportation facilities such as railway stations. TOD pattern brings convenience to the residents, however, may affect their indoor life quality at the same time. This article provides a new design methodology for vibration mitigation of TOD pattern based on periodic theory. The original design of waterproof curtain and retaining piles used in the buildings are reformed to be a periodic wave barrier (PWB) by minor adjustment without losing their original functions. After comprehensive numerical studies on the performance of the PWB, a detailed construction of the waterproof curtain and retaining piles is suggested, and it has been applied in practical engineering. The scheme proposed in this article not only is valid in practical engineering where operable space is very small, but also comprehensively considers the items such as construction technology and economic costs. Therefore, this study provides an innovative design for waterproof curtain and retaining piles that can be cost-effective and efficient, and is with the ability of vibration mitigation at the same time. •The original waterproof curtain and retaining piles have no attenuation ability for surface wave models.•The waterproof curtain and retaining piles are reformed to be a periodic wave barrier by minor adjustment without losing their original functions.•The proposed periodic wave barrier is suitable for small operable spaces, with low cost and good performance.
