REPORT ON WELDING PROPERTIES OF DIAGONAL THICK SECTION IN TRUSS FRAME USING TMCP440

In recent years, with the development of high-strength steel materials and improvements in welding technology, high-strength steel has been widely used in steel structure. In the Nagoya Zokei University of Art & Design project, 40m trusses is designed, and 100mm thick TMCP440 was used for the diagonal members. The erection plan required on-site welded joints at the ends of the diagonals, and ensuring the quality of the welds was a major construction management issue. Therefore, additional skill tests were conducted to find appropriate welding conditions and to confirm that the welded joints to be installed would have enough strength.
