Abstract
In this report, the author explains the compressive test results of the inclined fillet weld, discusses them in comparison with the tensile test results reported formerly and L. J. Vandeperre's test results, and intends to show that both tensile and compressive strengths of the inclined fillet weld can be explained well by the internal friction theory.
The relation (experimental) between α and the inclination of the breaking surface of inclined fillet weld (α=0°(end fillet)-90°(side fillet) ) under the tensile and compressive loads seems to approximate to the theoretical value by the internal friction theory (angle of friction φ=5°(tension) and (-) 45°(compression) ). Assuming that the tensile strength equals to the compressive strength of the side fillet weld, and that in tensile load, the smaller the angle α, the larger the frictional resistance between plate and strap, and correspondingly there is a substantial increase in the strength of the joint, by referring to Dr. Van der EB's test results, both tensile and compressive strengths of the inclined fillet weld will be well explainable by the internal friction theory.
