- Abstract
- This paper presents experimental and numerical investigations related to the block shear mechanism of double-lap welded
connections. The experiment investigation includes 36 specimens composed of 3.0 mm and 6.0 mm thick mild carbon steel
SS275 plates with varying block lengths and widths. It is found that the tension fracture in block shear of welded connection tends to be curved along the critical plane. The numerical results shows that the stress triaxiality efect in increasing the
tensile stress over the critical tension plane, and thus the tension resistance component increases. This paper also examines
the accuracy of various block shear strength equations given in the design codes as well as the literature. Topkaya’s equation
is found to be signifcantly more accurate than other block shear strength equations for the tested specimens. Nonetheless,
it is recommended to use the reduced tensile coefcient to ensure both safe margin and the accuracy.
