STRUCTURAL RESPONSES OF TRANSIT BUSES: IMPACT OF SEAT-BELT LOADS

In a 4-year study to assess the structural responses of transit buses under accident-induced loading, investigators conducted parametric finite-element computer analyses of actual transit buses. Various combinations of seat-belt use, seat type, and bus design were tested to measure the differential stresses generated in the structural members of these buses under passenger inertial forces generated by bus deceleration. Investigators concluded that with respect to the structural responses of typical transit buses to bus deceleration: 1) maximum member stresses should be lower with full versus partial seat-belt use; 2) maximum member stresses should be higher with wall-mounted versus floor-mounted seats; and 3) small to moderate changes in the number, size, and location of structural members from one bus design to another can have a substantial impact on the maximum member stresses.
