| 摘 要： | 对日本国新泻县某过街天桥垮塌工程进行了介绍,给出各方所持意见。通过参与实体试验及理论计算,对此次工程事故的原因进行了分析。认为索-钢-混凝土组合结构,由于材料变形能力的差异,以及小规模(小尺寸)构件的制作质量不易保证,该类结构对外界干扰所引起的变形极为敏感。总结认为,小构件采用此种结构需慎重。

| Abstract: | In this paper,the collapse of a cable-steel-concrete assembly platform bridge in Japan was introduced and different viewpoints about this collapse were provided firstly.The reasons of the collapse were analyzed by experiments and theoretical calculation.It is thought that because of the difference of deformable capacity between different materials and poor quality guarantee of small-size members,this cable-steel-concrete assembly structure is very sensitive to the extra deformation.We should be careful in applying this structure to members of small size. |
