HELP
Partial help is provided on each worksheet.
Procedure
Truck worksheetUse the scroll bar to choose the number of axles. Input axle Xcoordinates in ascending order beginning with 0.0 for the first axle. Input the axle weights
Bridge worksheet Use the scroll bar to choose the number of spans. For each span, input the span length L, uniform load q and number of divisions.
Click the compute button to run the truck
Do not forget to use consistent units throughout.

Program
Tips and tricks
2 to 20 axles and 1 to 5 spans with EI constant throughout. Truck will move from left to right with the first axle in front. Critical values of shears (absolute values) and moments will be computed on each division point. Total number of divisions must be less then 500. Results and graphs are displayed on Results, MEnvelope and VEnvelope worksheets.
Reverse the truck geometry to simulate moving from right to left.Instead of axle loads, use wheel loads multiplied by impact and lateral distributions factors to obtain quickly design moments, shears and support reactions.Use q(uniform load) to simulate lane load. Dead load or any other uniform load may be simulated by using zero axle loads.For a simple span, for example, AASHTO users may simulate lane load by choosing 2 axles with the 2nd axle weight set to 0.0.
