If you want to design cantilever soldier beams and wood lagging, then our SBWall software is all you need. However, if deep excavation earth retention support is desired, then most often, TBWall is a must.
When excavation cuts exceed 15 feet, the required section modulus of the soldier beam becomes increasingly large. It is therefore more economical to use a tieback wall soldier beam system. Up until now, you either had to do this by hand which is tedious or you had to use structural analysis software which does not take into account lateral stresses caused by apparent earth pressure.
The most popular and most efficient method of designing tieback walls is the method proposed by Blum, later modified by Tschebotarioff and others. This is known as the equivalent beam method which is a special case of the fixed earth support method & is also very close to the elastic line method.
TBWall software can handle upto 4 levels of tiebacks or approximately 55 ft deep excavation.(95% of the cases). This software allows you to enter the earth pressure loading, the tieback support levels, the beam shape (drop down menu), and tieback inclination. Other software stop here. However, TBWall also allows to enter vertical loading (axially loaded member check) & Lateral Torsional buckling check (LTB). Also a check is made for adequacy in Shear, Bending and Deflection. The charts have vertical orientation, just like the soldier pile and consist of loading, shear, moment, slope and deflection diagrams.
You may use either ENGLISH UNITS, in which case only compact sections of AISC W shaped beams would be displayed or SI UNITS, in which case metric beams and properties are shown.
Following Zip file will become full working version once registered.
