Research on Seismic Performance of External ALC Wall Panel Steel Frame System with Cross-shaped New Connector
The effect of a new cross-shaped joint on the mechanical properties of the whole specimen under seismic load were studied . A new flexible joint with high bearing capacity and durability was designed based on the common hook head bolt joint in construction . The mechanical properties of the new joint were analyzed through the combination of pseudo-static test and finite element numerical simulation,so as to verify its reliability. The results showed that the new cross-shaped joint had good seismic performance and energy dissipation capacity,which improved the bearing capacity and durability of the structure under seismic load,and were more practical and replicable than the hook-head bolt joint.
