PURPOSE: A truss type prestressed concrete girder is provided to ensure comparable performance to a complex truss girder and to obtain excellent construction ability and economic efficiency with the lighter body than an existing prestressed concrete girder. CONSTITUTION: A truss type prestressed concrete girder comprises an upper member (1), web diagonal members (2,3), a lower member (4), a single wall (5), an upper panel point, and a lower panel point. The upper member is made of reinforced concrete or fluorescent materials. A web diagonal member is made of reinforced concrete. The web diagonal members integrated with each other in order to change the directions at each lower panel point. The lower member is made of reinforced concrete. The upper panel point is formed at a point where the top end of the neighboring web diagonal members meet each other. The web diagonal member and the lower member in which a tensile force is generated due to an external load are formed with a continuous steel wire. |
