RetainWall is a software
mainly developed for the purpose of designing a concrete
or masonry retaining wall. The wall may retain soil or
other granular material. It analyses the stability of
the wall based on the loads and resistances, and results
pressure, sliding, overturning and
rotational stabilities. Loads
applied on the wall may consist of self weight, soil
pressure, water pressure, live and seismic loads.
Resistances may consist of
base friction and cohesion,
pressure, other structures or a shear key. Load and
resistance factor design (LRFD) mode can be applied. If the wall
is a reinforced concrete structure, the software also
supports the reinforcement design. In addition, a soil
pressure calculator is also provided.
RetainWall is designed to be an easy
application, on-screen trial-and-error method and quick
solution finding of the design. A familiar designer can
design the wall within minutes. Complete outputs can be
viewed on screen or printed.
Operation of the
software begins from the initial dimensioning of the
wall, earth surface and water levels by clicking on the
given dimensions. Next is inputting material properties
of the wall, soil, water and reinforcement bars.
External loads given consist of surcharge load, seismic load as a horizontal seismic
coefficient and any concentrated loads applied on the
wall if required. Load and resistance factors
combinations can be easily chosen. Results of the wall stability can be
obtained immediately. If they are not satisfied then
another trial can be made very quickly. There are also
options to use or not to use water, seismic or a
key. You have the possibility to print your final
Using the internal forces of the wall,
reinforced concrete design can also be done very
quickly. It requires only bar diameters and spacings of
