Data from: Experimental study on seismic performance of a low-energy consumption composite wall structure of a pre-fabricated lightweight steel frame

This study developed a low-energy consumption composite wall structure
constructed with a pre-fabricated lightweight steel frame that is suitable
for houses in villages and towns and evaluated its anti-seismic
performance. A low-reversed cyclic-loading test was conducted on four
full-scale pre-fabricated structure specimens, including a lightweight,
concrete-filled steel tube (CFST) column frame specimen (abbreviated as
SFCF), a lightweight CFST column frame composite wall specimen
(abbreviated as SFCFW), an H-steel column frame specimen (abbreviated as
HSCF), and an H-steel column frame composite wall specimen (abbreviated as
HSCFW). The failure characteristics, hysteretic behaviour, strength,
rigidity, ductility, and energy dissipation capacity of each specimen,
were compared and analysed. The results demonstrated that the
pre-fabricated, double L-shaped beam–column joint with a stiffener rib
which was proposed in this study worked reliably and exhibited good
anti-seismic performance. The yield, ultimate, and frame yield loads of
the specimen SFCFW were 1.72, 1.80, and 2.03 times higher than those of
specimen SFCF. The yield load, ultimate load, and frame yield loads of
specimen HSCFW were 1.27, 1.68, and 1.82 times higher than those of
specimen HSCF. This indicates that the embedded composite wall contributed
significantly to the horizontal bearing capacities of the SFCF and HSCF
specimens. The embedded composite wall was divided into multiple
strip-shaped composite panels during failure and achieved a stable support
for the frame in the later stages of elastoplastic deformation. The
horizontal strips of the tongue and groove connection between the
strip-shaped composite panels produced reciprocating bite displacements,
and ultimately improved the structure’s energy dissipation capacity
significantly.
