【摘要】 上海市山西路人行桥采用单跨54.5m变截面钢—混凝土叠合双铰刚构的结构形式。通过对该桥结构设计、景观设计及施工方法的简要介绍,得出梁高为1.6-2.6m、矢跨比为1/8.2;自振频率为3.06Hz;采用刚构撑脚处设置粗钢筋+圆板式橡胶支座连接的铰接方案,可取得满意的效果。更多还原

【Abstract】 Shanxi Rd. Pedestrian Bridge in Shanghai is of the single 54.5 m span double-hinged steel-concrete composite rigid structure with its cross section varied. From description of the structural design, landscape design and construction method of the bridge, it is concluded that satisfactory results can be obtained with the girder depth of 1.6~2.6 m, rise-span ratio of 1/8.2, natural vibration frequency of 3.06 Hz, and the proposed hinge of thick rebars at the foot of the rigid structure support connected with the disc elastomeric bearing.更多还原
