For sliding capacity : Why 1 foot is excluded to get the triangular pressure acting on the pedestal and footing? Is it per the code? What about the P to use? Is it P = axial load of the column + column self weight only? Thanks in advance for the reply.
Hello, and thank you for your great question! In some geotechnical reports, engineers may recommend excluding the top 1 foot of soil when calculating passive pressure for sliding resistance, unless it's covered by concrete or asphalt. CalcBook provides designers with the flexibility to choose whether to include or exclude this top 1 foot based on the geotechnical recommendations. For specific guidance tailored to your project, please consult your project's geotechnical engineer. The 'P' used for frictional resistance consists of the applied load (user-entered), footing weight, pedestal weight, and the soil weight above the footing. Note that CalcBook allows designers to select whether to include the footing weight, pedestal weight, and soil weight in the left input pane. This selection applies across all capacity calculations. Thanks again for your excellent question!
Hi @wesleybrewer3002 In the calculations, there is a reference pane along the right hand side of the calculation that refer to the section of ACI 318 where the equations or factors are taken from in the code. An example of this can be seen in the video around 14m20s mark in the “flexural capacity” section of the calculation (references are provided for beta, compressive strain, tensile strain, and phi, for example) Due to copyright, we cannot include explicit snips from the code itself, as only ACI has the rights to sell and distribute their codes. Hope this helps! If anything else, please ask.

Excellent Presentation and Graphics! Do keep up same and continue the Sharing!
Thanks! Any videos or design modules you'd like to see?

Looks Very Useful App ,,, But I am not Familer with Kip-Pound-Second So Pls can You share this app in SI Unit?
Thanks! Currently we are focused on building out the timber module, but including metric units is definitely on our to-do list after that
When you are looking through the calculations in the software, does it have ACI code refences you can view?

Can you share the program,plz
Hi @engkhalid7458, the program is available for download with a free two week trial on our website:
www.calcbook.com
hope it was explained manually , i hate softwares when it comes to design>>> so fast , not clear and randomly explained.
Thanks! We really focused on making sure that CalcBook provided a clear and detailed output for engineers to review and feel comfortable with.
