摘要
The present invention relates to a truss structure having an open-section upper chord member adapted to economise on steel materials and to improve the efficiency of truss bridge construction, by constructing truss bridges by using a truss structure for supporting truss bridges, wherein the open-section upper chord member of the truss structure is constituted in the shape of an upward-opening letter "U" so as to allow filling with concrete, and a steel material which is provided inside the open-section upper chord member is in tension. The present invention also relates to a method for producing the truss structure having the open-section upper chord member and to a truss bridge using the truss structure having the open-section upper chord member and also to a method for constructing the same.
