- Abstract:
-
A commonly used telecommunication cabinet in base transceiver stations was investigated in this study through shaking table tests.The tests results can be used to calibrate numerical model of the cabinets in following works.Shaking table tests for three cabinets(with telecommunication equipment in it)with the same specification were carried out.To consider the influence of randomness of earthquakes on seismic responses of the cabinets,three various earthquake records were input for each cabinet.The intensity of the earthquakes was increased until the cabinets were completely damaged.The damage mode and characteristics of the cabinets during the tests were observed and the seismic responses of the cabinets were recorded.The test results indicated that the cabinets begin to damage when the PGA of an earthquake reached 0.4~0.5 g.Weld between columns and beams of the steel frame in the cabinet began to crack at this moment.When the PGA of an earthquake reached 0.9 g,the beams at the bottom and top plates began to buckle.After the tests,the cabinets were totally damaged and could not be used.Through the tests,the seismic damage characteristics of this typical communication cabinet were known,and suggestions for improving the seismic performance of the cabinet were put forward.
