Inelastic behaviour of high strength steel members with low yield ratio

Structural members in a system are usually under stress gradient due to geometrical non uniformity and moment gradient. In such a case, the yield ratio of steel has an important role to provide ductility in the member's inelastic behaviour. Low yield ratio, in other words, high rate of stress increase after yielding, enables the yielding zone to extend over a wide area in the member as a source of plastic deformation or energy absorption. From tension testing, stub column testing, and CDC analysis, it was demonstrated that the newly developed 60kgf/mm**2 class high strength steel with low yield ratio exhibits higher ductility than the conventional one. From the pseudo dynamic testing using sinusoidal base acceleration, it was shown that the new steel shows larger energy absorption capacity even than the commonly used 50kgf/mm**2 class high strength steel. It is expected that this new high strength steel will be utilized in structural members especially in earthquake resistant buildings where plastic deformation is required as a source of energy absorption (A).
