ENHANCING SEISMIC CAPACITY BY APPLYING SILICONE ON WALL-SUPPORTED OFC IN BUILDINGS
This paper studies a non-intrusive fixture method to enhance the seismic capacity of operational and functional components (OFC) supported on walls to avoid damaging the wall and the OFC when installing. The force-displacement relationship of a simulated cabinet adhered by silicone to a wall was determined experimentally and a simplified equation to estimate for the strength of silicone adhesion by simulating the welding design concept is derived. Testing results showed that the strength of applying silicone is dominated by the out-of-plane loading. The lateral strength of 3 N/cm, about 63% weaker than the in-plane one, is proportional to the total installation lengths of the silicone runs. In addition, by performing three-axes shaking table experiment verified that a cabinet carrying 100kg contents can be prevented from toppling with a safety factor of 1.5 if adhered with leg size 2cm, length 120cm silicone runs on two sides of the cabinet.
