The size of the component of the anti-seismic support is mainly controlled by the slenderness ratio, and the section strength is far lower than the material strength, so that the material strength performance of the anti-seismic support is difficult to be fully exerted;
2) damage to the seismic connector results in the failure of the suspended non-structural member. Earthquake damage investigation and experimental research find that the connecting piece of the earthquake-resistant support and hanger is an earthquake-resistant weak part, and the damage of the connecting piece easily causes the suspension type non-structural member to lose effective support and damage the suspension type non-structural member;
