WALLAP - Retaining Wall Analysis software
Copyright 2002 by D.L.Borin

WALLAP version 5.01 is the first Windows version of WALLAP.
Version 5 has been designed to provide a high degree of compatibility with its predecessor, version 4.10, at many levels:-

Data
Version 4 data files (both Standard and Large versions) can be read and processed by Version 5.
The definition and usage of all engineering parameters is preserved in version 5.

Calculations
The methods of calculation are identical apart from:-
       Revised criterion for maximum water filled tension crack depth
       Revised arching active pressure calculation

Output
The formatting of printed data and results is preserved virtually unchanged.

The maximum numbers of data items (strata, soil types etc...) are now as follows:
max no. of strata on either side of wall = 40
max no. of soil types = 40
max no. of struts and anchors = 40
max no. of moment and surcharge loads = 40
max no. of pore pressure points = 20
max no. of pore pressure profiles = 20
max no. of construction stages = 80

These limits are larger than those of the standard version 4.10 program and correspond to the limits of the "large" version 4L.10 program.
Old data files of all version 4.10 programs can be read by version 5.01
The maximum number of nodes which the program may generate for the analysis is now 80. The number of nodes generated is not directly controlled by the user but is a combination of the number of different strata elevations, struts, water pressure profiles, and applied loads. The increased limit gives greater flexibility to model complex problems.
