RetainWall version 2.60 – A powerful software for designing a concrete or masonry retaining wall

Dhani Irwanto has developed RetainWall. It is an exclusive software that can be used for making the design of a concrete or masonry retaining wall. The wall may preserve soil or other granular material.
It examines the strength of the wall on the basis of the loads and resistances, and leads to bearing pressure, sliding, overturning and rotational stabilities. Loads which operate on the wall may include self weight, soil pressure, water pressure, live and seismic loads.

Resistances may contain base friction and cohesion, passive earth pressure, other structures or a shear key. Load and resistance factor design (LRFD) mode can be employed. If the wall is a reinforced concrete structure, the software can also produce the reinforcement design for any reinforced concrete structure wall. Besides, there is a soil pressure calculator.
This user-friendly application provides on-screen trial-and-error method and instant solution for the design. With it, any designer will be able to design the wall swiftly. Complete outputs are visible on screen or printed.
The software starts it’s operation by clicking on the specified dimensions to produce the initial dimensioning of the wall, earth surface and water levels. After that, it enters material properties of the wall, soil, water and reinforcement bars. Provided external loads contain surcharge load, seismic load as a horizontal seismic coefficient and any concentrated loads implemented on the wall if necessary. Load and resistance factors combinations are easily selected. Results of the wall stability are gained immediately. If satisfactory result is not obtained, then another trial can be produced instantly. You can also choose from options to use or not to use water, seismic or ashear key. The final results can also be printed.
The reinforced concrete design can be made instantly by applying the internal forces of the wall. It only needs bar diameters and spacings of the reinforcements.
RetainWall is compatible with metric, SI and British unit systems.
Given below, some exclusive features of the software :-
a. Ability to design Load and resistance factors.
b. Apply load and resistance factors combinations from AASHTO LRFD 2007, ACI 318-08 and IBC 2006.
c. Load and resistance factors editor to change or generate new combinations
d. Concrete reinforcement design from ACI 318-08.
e. Force diagrams (moment, shear and normal) for every combination.
f. Loads, resistances and reactions diagrams for every combination.
g. Wall stabilities (bearing, sliding, overturning, rotation) for every combination.
h. Workout nominal soil bearing resistance by applying theoretical or semi empirical methods.
i. Ability to select active or at rest soil pressures.
j. Ability to select elastic (rock) or plastic (soil) bearing pressures.
k. Ability to enter user's soil pressure coefficients.
l. Reinforcement design for upper stem, lower stem, toe and heel.
m. Unit systems, properties, load and resistance factors, reinforcement design method, and page setup from last editing which turn out to be the default for new design.
n. Ability to include other loads on wall.
o. Offer stability resistances from a shear key, toe passive soil pressure, adjacent structure, anchors or piles.
p. Enable or disable a shear key, water or seismic.
q. Various types of units of measurements like metric, SI and British unit systems are supported.
r. Easy, clear, quick and simple software operation.
s. Help facilities, can be printed to produce manual.
