TeFC

TFC is a Temperature field calculator based on finite differential method. For calculating the transient temperature field in the structure, the energy flow on the surface of the pavement are analyzed.

Details of the algorithm will be added later.

StaticFWD

StaticFWD was modified from StaticPave.

StaticFWD uses a static algorithm to calculate the pavement deflection response under falling weight deflectometer(FWD) load. Unlike Bisar3, it can handle a lot of input datas once and calculate together. The results are written to one output file.

StaticPave

StaticPave can calculate the pavement response under static load, such as stress, strain, and displacement. It can deal with any number of load at any form, and compute the response at any point of the struture. It can be used in the pavement design and detection.

This program takes a text file as input data source, and outputs the calculating results to another text file. The file names are assigned by the user.

It is coded in fortran and is OS independent.
