q690d proportion Related introduction

  1. Experimental and numerical investigations of Q690D H ...

    Hysteretic behavior of Q690D steel H-section column was experimentally evaluated. Extensive parametric analyses were conducted based on the verified numerical model. Effects of axial force ratio and geometrical dimensions were investigated. A trilinear hysteretic model for welded Q690D steel H-section column was proposed.

  2. Experimental study on fatigue performance of high strength ...

    But for the butt-weld specimens of Q690D, the fatigue limit of AISC360 and EC3 was 36.75% lower than the test value of the 95% assurance rate. The BS7608 curve, lower than AISC360 and EC3 curves, was relatively conservative to evaluate the fatigue performance of butt weld specimens.

  3. Experimental investigation on cyclic behavior of Q690D ...

    Q690 high strength steel (HSS) is a structural steel with yield-to-tensile ratio being generally greater than 0.90 and elongation lower than 20%, resulting in considerable decrease in steel member ductility.

  4. Experimental study on fatigue performance of Q460 and

    In order to study the fatigue characteristics and laws of high strength steel bolted connection, referring to GB/T 2975-1998 "Steel and Steel Products-Location and Preparation of Test Pieces for Mechanical Testing" , the test materials using 8 mm thick Q460D and Q690D high strength steel and it is sampled at full thickness.Three group specimens were designed for this test material.
