Moving truck (up to 20 axles) analysis for bridges with simple or continuous spans (up to 5). Envelopes (M & V) and support reactions.
2 to 20 axles and 1 to 5 spans with El 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.
Tips and Tricks
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.

Builds two-dimensional bridge models and performs static and moving load analyzes. Uses GT STRUDL as a structural analysis engine.
MOVLOADS is a spreadsheet program written in MS-Excel for the purpose of analysis of simple-span members subjected to from one up to eight moving wheel loads with up to seven wheel spacings.
This is a small engineering tool that calculates member forces and support reactions of a continuous beam. It is based on CBA. m for matlab/octave by Colin Caprani
Abnormal Load Vehicles, HB Vehicles, BD21 Annex D Vehicles and BD86 STGO Vehicles are analysed as moving loads across a single or multi-span continuous line beam to determine critical bending moments and shear forces.
