Abstract: To investigate the effect of sustained loads on the ultimate strength of high-strength composite columns using grade 800-MPa steel and 100-MPa concrete, ultimate load tests were performed after long-term loading. Two ...

Abstract: Composite columns of various sectional configurations are studied to maximize the contribution of high-strength steel under compression-flexural loading. For concrete-encased steel (CES) columns, steel angles were placed ...

Abstract: Two concrete-filled steel tube columns and four concrete-encased steel columns using high-strength steel (yield strength

Abstract: Seven concrete-encased steel columns using high-strength steel (nominal yield strength
