| 摘要 |
The present invention relate to a steel box truss girder connecting a lower chord steel pipe and a steel box having an arc-shaped upper part by using an inclined member and, more specifically, to a steel box truss girder capable of dispersing load applied to the upper part of the steel box by using a means for applying the compressive force by installing a cable which is pulled in the lower chord pipe in the lengthwise direction of the girder. The present invention comprises: a steel box having an arc-shaped central upper part in the lengthwise direction of the girder; a lower chord member steel pipe arranged in the lower part of the steel box in the lengthwise direction; and an inclined member connecting the steel box and the lower chord pipe, wherein the lower chord pipe has an arc-shaped central lower part in the lengthwise direction of the girder. The steel box truss girder can generate downward force by a cable installed in the lower chord pipe and pulled. |
