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: In the present study, a new fabrication method is proposed for concrete-filled hollow precast concrete columns (HPCC). In the proposed method, corrugated steel plates were used for the internal mold of the hollow core ...

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

Abstract: Existing experimental results show that carefully designed RC column-to-steel beam (RCS) joints have high seismic resistance comparable to those of traditional steel or RC frames with seismic details. However, such high ...
