APPARATUS TO TEST DYNAMIC LOAD OF LONG-SPAN BRIDGE

摘要

The present invention relates to an apparatus to test a dynamic load of a long-span bridge. More specifically, a dummy vehicle to generate an actual weight of a vehicle and a holder capable of holding a bridge are disposed, and the dummy vehicle is moved to a front and rear side of the bridge such that impacts applied to a sectional bridge structure by a dynamic load is measured and structural stability is able to more accurately be evaluated. The apparatus comprises: a holding means to hold a bridge, including a pillar frame and a support frame; a dummy vehicle designed to have a center of gravity and a weight which is the same as that of an actual vehicle to pass through the bridge, including a suspension device disposed on a bottom side thereof identical to an actual vehicle, and having guides formed in the front and the rear thereof; and a vehicle driving means including brackets respectively attached through both ends of the support frame, including a hydraulic winch installed in each of the brackets.;COPYRIGHT KIPO 2017
