We are glad you found the video helpful! The image shown when calculating “c” has two parts: 1) A cross section (cut horizontally) of a shear wall showing the total length of the wall 2) The assumed strain distribution, showing the assumption that plane sections remain plane. “dt” shows the distance from the location of max compressive strain (= 0.003 in this case per ACI) to the location of maximum tensile strain, at the steel bar closest to the opposite edge. “c” shows the distance between the neutral axis and location of max compressive strain.

@@calcbook Thanks for the explanation👍

This is using AISC which is explicitly for steel.

Hi, we use a number of different apps to make our graphics including canva and inkscape.

CalcBook does not offer out-of-plane loading... yet! It is something we are working on and will be releasing soon. We'll be sure to upload a tutorial video when it is out. Thanks!

@@calcbook looking forward to it, beautiful work

Coming very soon! Work is in progress.

Hi! You can buy CalcBook at our website here: www.calcbook.com/professional-pricing

Hi @SubtainSajid-s9m, We appreciate the comment and always like when people keep an eye out for errors. Your first comment is valid for what is shown in the original video. This has already been noted in the description, and updated in CalcBook some time ago. We would also like to note that the use of cosine resulted in overly conservative results. Your second comment is not an error, but follows the guidance of chapter F11 of AISC 360-22. Equation (F11-1) specifies a factor of 1.5 for rectangular members which is what is being checked here. Equation (F11-2) specifies a factor of 1.6, but this only applies to rounds, which is not applicable here. Note, this video covers the 16th edition, AISC 360-22. Your second comment would be valid for the 15th edition, AISC 360-16, but they updated to 1.5 for rectangular bars in the 16th edition, AISC 360-22.

A moment in the continuous column should not impact the check of web panel-zone shear, HOWEVER, you may need to check for a variety of other possible failures including: flange local bending, web local yielding, web local crippling, web sidesway buckling, and web compression buckling. We cover these in our simple moment connection video here where there are moments in both the beam & column: kzbin.info/www/bejne/apelfKyCea2YnNk&ab_channel=CalcBook

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.

CalcBook! You can try it for free for two weeks by visiting calcbook.com and downloading the free trial

@@calcbook how much it for one year ?

@@mohamedag8366 our professional pricing options are listed on our website at the link below, there are monthly and annual subscription types available: www.calcbook.com/professional-pricing

Not currently, but it’s in active development along with the implementation of the NDS timber code!

Thanks!

Thank you! We release a new video each week highlighting the capabilities of CalcBook!

Nice to hear! Any specific topics you’d like to see covered in future videos?

​​@@calcbookModelling a structure would be good!?

Hello - CalcBook does not offer out-of-plane loading... yet! It is something we are working on and will be releasing soon. We'll be sure to upload a tutorial video when it is out. Thanks!

Hi @engkhalid7458, the program is available for download with a free two week trial on our website: www.calcbook.com

Hi @uglyjordanuglyjordan1744, Sorry to hear that! What in particular are you looking for? Maybe we can incorporate that into our future video(s)!

Thank you! We have lots of AISC design topics coming. A new video every week.

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!

Thanks! We really focused on making sure that CalcBook provided a clear and detailed output for engineers to review and feel comfortable with.

You are welcome! Any other videos or design modules you'd like to see?

@@calcbook Yes, please

Thanks! Currently we are focused on building out the timber module, but including metric units is definitely on our to-do list after that

Hi @KAMILWIJDAN, CalcBook has a free two week trial available for download on our website.

Thanks!

Thanks! Any videos or design modules you'd like to see?

hi @ahmadramadanwahbeh1071 For standard shapes as shown in the video, rts comes from Shapes Database put out by AISC For custom shapes, rts is calculated as described in the user notes of Chapter F of AISC360 The Show-Your-Work for rts is shown on the "General" tab in CalcBook by expanding the Geometric & Material Properties section. Hope this helps!
