Traffic Load: Load Trains


In Analyzer\Structure\Load Definition\LoadTrains the Load Trains are created as a series of uniform line loads and concentrated point axle loads to be applied with the respective factors at each Traffic Lane. One basic typical input is shown in the application screenshot below with two distributed loads Q=-15kN/m until the beginning and at the end of the structure and two concentrated F=-200kN forces. Note that the negative sign indicated the Y direction for gravity and one additional null force is inputted, with zero value, to create the first gap between the point loads. A graphical view of the input is available at "i" information button as indicated by the red arrow. Usually the loads are an axle load applied in the center of the lane but, surface loads are also available by additional input, i.e., different from the default value 0. Several code specific options are also available, as well as some Live Load Macros, and more information can be found at the Help F1 or at the RM Bridge User Manual. In the Main Screen at the View Menu options (accessible by right clic mouse) user can select to include Load Trains at specific positions, in the current view, as shown below.
