Abstract

A thick steel shear panel fabricated without welding is examined in order to investigate its feasibility as a passive control device. Numerous small size specimens of three different steel materials are examined both experimentally and analytically. Under monotonic loading test, the specimens exhibited extremely large deformation capacity as well as large maximum strength, far beyond those of ordinary shear panels. Under cyclic loading, they also demonstrated significant fatigue life as much as 250 times those of ordinary thin panels. The same material is tested under axial monotonic and cyclic loads in order to compare with the shear loading case. It is found that the monotonic and cyclic stress-strain relationship and even the fatigue life are closely correlated between the two different loading cases. Based on such a correlation, a method of conversion from one loading case to the other is proposed.
