Abstrait:

Irregular-shaped footbridge scheme was determined due to urban landscape requirements, the subway constraints under the bridge and crossroad traffic condition. But the deformation and vibration of Irregularshaped structure will be complicated. To study the static behavior and vibration serviceability of Qingchun irregular-shaped footbridge in Hangzhou, the support reaction under the temperature influence and dynamic performance in pedestrian was calculated by using finite element method. The results of analysis show that the uneven deformation of irregular-shaped structure caused by temperature load will lead to support separation, and this issue can be solved by adding additional weight near the top of the pier; First-order vertical frequency needs to be increased by adjusting the beam height to meet the comfort requirements of Chinese code.
