Software for evaluation of equivalent loadings

Evaluation of Exceptional Loads


ABload software evaluates the admissibility for transit of exceptional loads on a road network.
The assessment is made by comparing the design loads of the construction period and the
expected exceptional load in transit, also considering the effects of the transverse
redistribution of loads. Assessment of the admissibility of free, conditional or exclusive transit.

About ABload

ABload (Abnormal loads) software, calculates bending and shear equivalent loadings due to any series of concentrated and/or distributed loadings moving on a beam with span varying in a predefined interval. Currently software is available only in italian language.
In preprocessing ABload allows to archive in a database train loadings, administrative data, and geometric data of the bridges.
In post-processing is possible to analyze results and to compare them with results given by loadings from principal historic code of practice.

Software has four principal input/output windows:

  • Loading definition
  • Equivalent loadings analysis
  • Maximum internal pressure
  • First and second level analysis

Data Sheet

Loading definition

“Loading definition” window

Loading definition” window is splitted in three areas:

1. Abnormal loading definition
2. Graphical scheme
3. Analysis

Analysis can be run with three different way of transit:

– Free
– With Conditions
– Exclusive

Equivalent loading and maximum pressure analysis

“Equivalent loading analysis” window

Equivalent loading analysis” e “Maximum pressure analysis” windows, have the same structure and are divided in four areas:

1. Choice of analysis loading
2. Graphical output of results
3. Results formatting
4. Single span results

View and printed reports are available with graphs and tables that describe the performed analysis.

First and second level analysis

“First and second level analysis” window

First and second level analysis” window is divided in four areas:

1. Data analysis in a tabular form
2. Automatic calculation of Courbon and Massonet coefficients for transversal redistribution
3. Abnormal loading description in current analysis
4. Design loading description in current analysis
5. Summary table
