Can anyone help me with Multi Step Bridge Live Load Pattern Generation? I am having trouble in understanding how different parameters are set namely Start Distance, Start Time, Speed etc. The problem is how do I identify the critical case such as how many vehicle will cross the bridge at the same time?

I have modeled a simple 6m long concrete circular column of 760mm diameter. I have applied a joint live load at the top of the column. Selecting ACI-318 as design code with frame type as sway special, I get the flexural and shear reinforcement. However, when I change the design code to AASHTO Concrete 2007 in the design preferences with zone 3 in overwrites, I get nearly same flexural reinforcement as by ACI but I observe a huge difference in shear reinforcement. It is to be noted that I have used same combination while designing by both codes. Please check the file attached and explain. G.SDB
