| Research Abstract |
To improve the deformation capability of the steel structure beam-to-column welded connection, using specimens such as the following, were subjected to many fracture experiments. Test specimens are the following four types. The pseudo non-scallop method on site welding, the method of drilled flange, the flange widening method and the method that left fillet of scallop part of the H-shaped steel.
Then I was subjected to a three-dimensional finite element method analysis. I examined the method for determining the number of holes available in the method of drilled flange. In addition, the height of the remaining fillet was confirmed to be around 2mm is appropriate. As a result, it could be proposed several recommended method for improving the deformation capacity.
