ON THE STRENGTH AND DUCTILITY OF STEEL STRUCTURAL JOINTS SUBJECTED TO HIGH SPEED MONOTONIC TENSILE LOADINGS

By 潔 金多, 功夫 甲津, 貴夫 木上 and 英貴 奥田

Abstract

This paper deals with an experimental investigation to estimate the influence of strain rateon the strength and ductility of several steel structural joints due to high speed monotonic tensileloadings.The galvanized bolted joints used for towers as well as the ordinary joints in buildings, thatis, the butt welded joints and the high strength bolted joints, have been tested and the resultswere compared with those of the base metal of mild steel.From the test results, it has been concluded that, since the mode of joint resistance and thegeometry of the bolted joints can affect remarkably the yield and the ultimate strength underhigh speed monotonic loadings, the strengths of the joints may not be directly estimated fromthe result of the base metal.This paper deals with an experimental investigation to estimate the influence of strain rateon the strength and ductility of several steel structural joints due to high speed monotonic tensileloadings.The galvanized bolted joints used for towers as well as the ordinary joints in buildings, thatis, the butt welded joints and the high strength bolted joints, have been tested and the resultswere compared with those of the base metal of mild steel.From the test results, it has been concluded that, since the mode of joint resistance and thegeometry of the bolted joints can affect remarkably the yield and the ultimate strength underhigh speed monotonic loadings, the strengths of the joints may not be directly estimated fromthe result of the base metal
