I am modeling the span between 4 trusses, trying to get the DF for the trusses based on a truck moving load.
The model I have has three beams framing into 4 trusses as a continuous simply supported beam w/ 3-rollers. My problem is limiting the range where my load can go:
LOAD GENERATION 700
TYPE 1 0 0 0 XINC 0.05 XRA 8.30 54.65PERFORM ANALYSIS PRINT STATICS CHECKFINISH
I thought that XRA would allow me to limit the load from going on the curb on both sides of the truss... but I'm having an issue with the program syntax. Is it because the XRA should be given in terms of nodes not distance along the member or am I missing on something else here?
any follow up with replies? I have the same problem/question. Thanks
