I have applied a moving load and get a number of warning messages like the one below

**WARNING-A MOVING LOAD THAT WOULD HAVE BEEN APPLIED BEYOND THE X AND Z RANGES  OF THE STRUCTURE HAS BEEN IGNORED ..." .

Is there a problem and are the results affected due to the warnings ?

These warning messages indicate that some of the wheel loads, generated by the moving load generator, are falling outside the boundaries of the structure and those loads are going to be ignored by the program.

Sometimes in order to ensure that all the wheel loads traverse the entire length of the structure, users may have to deliberately provide enough number of generations which may cause some wheel loads to go outside the bridge deck (typically those in the front) while the rest are still within the deck (ones in the back). Situations like these will trigger warnings but it does not mean that there is a problem and it would not affect the analysis adversely. Although these warnings are mostly inconsequential and may be ignored but nevertheless one should check the inputs to ensure that the loading has been applied as per requirement.
