Once all input data is entered, you initiate the analysis. The software will perform calculations based on the linear elastic theory for multi-layer systems. BISAR allows you to calculate responses at specific coordinates (X, Y, Z) within the pavement and can combine the effects of multiple loads to simulate a moving vehicle.
