摘要
铝合金人行天桥在全国范围内已建成多座,但由于铝合金材料自身的特点,在设计过程中应注重多方面的复核。依据杭州复兴路人行天桥建立模型,利用ANSYS有限元软件辅助,就铝合金人行天桥的自振频率及稳定性进行重点分析计算,以期为以后的应用发展做出贡献。
Many aluminium alloy pedestrian overpasses have been built in China.However,the recheck has to been focused in many aspects in the course of design because of the characteristics of aluminium alloy material.Based on the model built for Fuxing Road Pedestrian Overpass of Hangzhou,the natural vibration frequency and the stability of aluminium alloy pedestrian overpasses are focused on analysis and calculation by utilizing the ANSYS finite element software so to make the contribution for the application and development of its future.
