Through-beam connections offer the effective performance in developing the rigid connection, but the practical applications often encounter concrete pouring difficulties at the through beam region. Then an advanced through-core connection between concrete-filled steel tubular (CFST) columns and steel-concrete composite (SCC) beams is proposed in this study. The modification emphasizes the reduced beam flange width to convenient the concrete pouring, and the penetrated slab reinforcement into the CFST column to make up the strength loss from flange reduction. To investigate the seismic behavior of the connection, quasi-static cyclic loading tests on four specimens are conducted, and correspon..View full abstract
