Study on the ultimate strength and deformation to eccentric compression made of high-performance steels with H-shaped cross-section columns

Abstract

High-performance steel materials (SBHS, SM570) are stronger than SM490, so they are effective in improving the seismic performance of bridge structures. However, it cannot be used for seismic design of bridge piers, etc., and the performance of high-strength steel cannot be fully exhibited. In order to enable seismic design using high-performance steel materials, it is necessary to accumulate data on the plastic region of high-strength steel materials.
