CONTINUOUS SUPPORTING STRUCTURE OF CORRUGATED STEEL WEB PSC BEAM USING SECONDARY TENDON AND METHOD FOR CONSTRUCTING THE SAME

摘要

PURPOSE: A continuous support structure of a PSC girder using a secondary tendon and a method for constructing the same are provided to enhance the field workability of a continuous support and improve appearance since there is no need for a separate tendon arrangement. CONSTITUTION: A continuous support structure of a PSC girder using a secondary tendon is as follows. Two girders(G1,G2) are coupled to pier(P) by a joint plate(101). Continuity is made using a secondary tendon(133) that is arranged based on an increased load during construction.
