Dynamic behavior of skew, single-span hollow slab prestressed concrete bridge with span length of 17.80 m was investigated; because of short span of bridge, it was decided to choose locomotive to represent live load; tests were carried out with Class 41 steam locomotive which has four driven axles and weight in working order of 176.1 metric tons using correlation theory; fundamental natural frequencies calculated from measurements of flexural vibrations of bridge under load of test locomotive ranged from 4 to 5 cps; damping effect calculated from tests amounted to 0.032.
