Description

<p>To investigate bending characteristic of the plastic hinge of steel bar-timber composite column under lower to higher levels of axial force, compression test and cyclic bending test of column were conducted, and it was revealed that compressive stiffness, and compressive strength of the hinge were greatly increased by steel bars, and moment-rotation angle relationship of the hinge from low to high axial force and its correlation curve between axial force and bending strength were clarified. Furthermore, the correlation curve and the cyclic moment-angle relationship could be estimated accurately by the plasticity theory and the calculation method for reinforced concrete.</p>
