Experiment Research on Seismic Performance of Framework Joint Connected with Strengthening Planting Bar

This issue conducted the low cyclic reversed loading test of 3 groups of framework joints formed by inorganic anchorage materials and 1 group of the one formed by integral concreting. This paper study the seismic performance, analyzed the hysteretic curve, bearing capacity, ductility and the capacity of energy dissipation of the framework joints. The conclusion can be obtained that the bearing capacity of framework joints connected with strengthening planting bar are better than the ordinary joints. The ductility and seismic performance are good.
