The invention provides a damping structure for a ceiling system. The damping structure comprises a first keel, at least one T-shaped connector, at least one first connecting rod, at least one second connecting rod, at least one spring and at least one second keel. According to the damping structure for a ceiling system, when the ceiling system endures abnormal impact or acting force, the spring is stretched by the first connecting rod and the second connecting rod through hinging among the first connecting rod, the second connecting rod and the T-shaped connector, and a rigid force acting on the ceiling system is transformed into an elastic force of spring extension, so that adverse influence of impact on the ceiling system is counteracted, the anti-seismic property of the ceiling system is reinforced, and smooth progress of the construction process and the quality stability of the damping structure can be guaranteed.
