Moving continuous load

For large-span bridges the problem of the effects of a moving continuous load is of equal — if not greater — importance than the problem of a moving concentrated force. It has been treated at length by several authors, 1.1. Gol’denblat [97] and V. V. Bolotin [20] among them. In the next sections we shall deduce a stationary solution for the case of a moving endless strip of load also with the approximate effect of its mass, and an approximate solution for the load arrival to and departure from the beam. In conclusion we shall review some of our experimental results.
