ABSTRACT

tests, with large diameter-to-thickness ratios (D/t=70 and 100), were about 70% of the tensile strengths. However, for typical moment connections the difference between the absolute value of compressive and tensile stress in the upper and lower beam flanges is not very much, and the depth of the beam is almost one or two times the diameter of the column. Hence, the compression strength of connections is not significantly decreased as the simplified compression tests would suggest because of the interaction of the tensile and compressive local deformations.
