THE EFFECT OF WELDS GEOMETRY IN FRACTURE OF WELDED FLANGE PLATE CONNECTION IN I.R. IRAN
Failure of the CJP groove weld at the top and bottom plates in welded flange plate (WFP) connection is the main cause of the observed damages in Iranian steel structure. In steel skeleton sites, welding of top and bottom plates is always encountered with some problems. Sometimes, due to lack of awareness of contractors of the importance of CJP groove weld the preparations of the plates are not performed properly in construction. In addition, the inspectors ignore to check the welds because of the height. These are the main cause of not having a perfectly penetrated weld in CJP groove weld. Moreover, when the inspection is done and the flaws are observed, instead of grinding the welds, they are strengthened by fillet weld. In some cases, the fillet weld is used. In this paper, by the means of static and dynamic tests on specimens of top and bottom plates, different method of welding are compared and discussed.
