Tensile Behavior of Concrete‐Filled Steel Tubular Column Splices Using Perforated Steel Plates

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
This study proposes a CFST column splice design transferring stress through infilled concrete using welded perforated steel plates. Pull‐out tests on the perforated steel plates were conducted to develop a strength prediction formula, which was validated through tensile experiments on column splices and predicted their tensile capacity.

Study on the Joint Performance of Concrete‐Filled Steel Tubular Columns With Unequal Depths Above and Below the Diaphragm Plate

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
This study investigated the seismic behavior and stress transfer mechanisms of through‐diaphragm beam‐to‐column connections of CFST columns with different upper and lower sizes. An ultimate strength formula based on yield‐line theory that incorporates concrete bearing resistance is proposed, and its predictions agree well with the experimental results.
