Moving Loads According to AASHTO Standard

Design loads specified in the AASHTO Bridge Design Specification are available in the RF-MOVE Surfaces moving load library. Design Truck (HS-20), Tandem, Type 3, and Overload are available options.

In addition, Cooper E-80 loading (with and without cars) from the AREMA Manual for Railway Engineering are also included in the library.

The AASHTO and AREMA database can be launched in RF-MOVE Surfaces under Table "1.3 Moving Loads". Utilizing the filters on the left, select the desired moving load to be applied to the structure in RFEM. The load magnitude, axel spacing, tire width, tire length, and distance between tires will be generated automatically, depending on the selection.

The input of step size, offsets at the start and end, and the distance from the reference line will also influence the moving load cases. Once generated, the RF-MOVE Surfaces load cases can be viewed graphically in RFEM.
