HELP

Partial help is provided on each worksheet.

Procedure

Truck worksheetUse the scroll bar to choose the number of axles. Input axle Xcoordinates inascending order beginning with 0.0 for the first axle. Input the axle weights

Bridge worksheetUse the scroll bar to choose the number of spans. For each span, input thespan length L, uniform load q and number of divisions.

Click the compute button to run the truck

Program

Tips and tr icks

2 to 20 axles and 1 to 5 spans with EI constant throughout. Truck willmove from left to right with the first axle in front. Critical values of

shears (absolute values) and moments will be computed on eachdivision point. Total number of divisions must be less then 500.Results and graphs are displayed on Results, MEnvelopeandVEnvelope worksheets.

Reverse the truck geometry to simulate moving from right to left.Instead of axle loads, use wheel loads multiplied by impact andlateral distributions factors to obtain quickly design moments, shearsand support reactions.Use q(uniform load) to simulate lane load. Dead load or any otheruniform load may be simulated by using zero axle loads.

For a simple span, for example, AASHTO users may simulate laneload by choosing 2 axles with the 2nd axle weight set to 0.0.
