With the advent of electrically driven and computer controlled rapid transit vehicles for mass intraurban use, it has become necessary to investigate the dynamic efficiency of different types of elevated spans for these vehicles. In previous work involving moving point forces on continuous span bridges with hard piers, dynamic moments of nearly five times the static response of its simple span counterpart were measured. This paper looks to the alternative of a continuous cable-stayed bridge for a reduction in the moment amplification. Energy is expected to be distributed in more vibrational modes and partially absorbed by the cable supports.
