In a world driven by technology and digital innovation, the significance of hand calculations might seem overlooked. In this video, I'll be talking about the benefits of hand calculations to structural engineers and its major drawback. In the end, I will share the tool that I use every single day to solve this problem.

Great video! The black boxes in existing structural engineering software & the tedious task of constantly updating calculation templates in spreadsheets or mathcad is exactly what drove us to develop CalcBook!

I'm just a little over a year into my structural engineering career and I've had the good fortune to be allowed to do a deep dive in producing my own MathCAD calculation templates for ASCE 7-(10/16). Doing my calcs in this way gave me not only the chance to gain a fundamental understanding of the principals, assumptions, and intended approach of the analyses contained therein, but has also allowed me the convenience of reusing my calcs templates over and over again with some minimal to moderate amount of modification in between jobs. Thanks for highlighting this subject; I'm learning firsthand just how powerful gaining an intimate under-the-hood understanding of the Code can be towards developing a solid problem-solving toolbox. Please keep these topics coming!

You're totally right on the pitfalls of black box analysis software or spreadsheets, and it's really beneficial to write down the problem so you can better develop your skills as an engineer. Mathcad also combines the benefits of hand-based computing with the speed of doing calculations digitally, as well as the efficiency to be able to repeat calculations and reuse them over and over (especially with smart template use). And other great benefits like attaching and balancing units, which may be overlooked when doing hand calculations.

Great video! I have been looking for online articles related to civil engineering, and I am struggling to find ones that I can trust as credible with good information. I was wondering if you knew of any good websites with information on the topic? I enjoy watching your videos, but sometimes I learn better and absorb information easier when I am able to read it. I am a high school student very interested in going into structural engineering, but I would like to learn a little about it before I decide if I am going to take that next step. Thanks for the information-filled videos, they are really helpful!!

Another problem is that hand calculations take time. Most often the client wants the answer asap and rather a slightly overdesigned solution. *But* as you said, hand calculations are a great way to make sure you understand the fundamentals of a design.

@BrendanHasty 10 месяцев назад

Agree, and with a dynamic calculation, you are able to provide both efficiency and detailed calculations

Great Video Brendan!! Thanks for the content.

@malikdaniyel146 10 месяцев назад

I do agree hand calculations can be time consuming but it provides the basic fundamentals for simple design. Spreadsheets are my main tool I use to provide simple design answers when onsite.

@BrendanHasty 10 месяцев назад

Hi Malik, agree that most people go to tool is Shreadheets, but I think especially for one-off calculations. But for these types of assessments, I have always preferred a Dynamic Calculation.

@romliahmadabdulnadzir1607 10 месяцев назад

Engineers are limited to the use of hand calculations and physical tests. While these methods do an adequate job of ensuring that the design meets performance requirements, they provide limited performance insight and often require the use of a guesswork, test, and check approach to the design. Hand calculations also limit the amount an engineer can optimize a design because complex designs are often too difficult to analyze by hand.

@BrendanHasty 10 месяцев назад

Hi, hand calcations are a must for anyone running any detailed analysis to ensure the assessment is behaving correctly or even in the ball park. most of the time too you need to assess the system to code and standards which at points required a Calculation, even if it is assessment of the stresses out of a FEA analysis

@billj5645 10 месяцев назад

This is always important but especially when doing hand calculations- 1. Always label your units. Be sure not to mix different units such as feet and inches, or various metric units. 2. Always label whether your calculations are for service level design or strength level design. There are lots of different terms used for these such as ASD or unfactored, vs. LRFD, ultimate strength, or factored.

@BrendanHasty 10 месяцев назад

Hi Bill, totally agree all units should be labeled, and a clear design criteria listed, eg ASD, LRDF, ULS, SLS. thanks for the ongoing support.

I use Mathcad. From what I can see, it's similar but mathcad has more features. Can you plot graphs or integrate excel sheets into Mathjot?

@BrendanHasty 10 месяцев назад

Hi you are able to plot graphs, there is a quick tutorial on how to do this and it is currently being worked on how integrate with excel

@soumyadeepghosh5000 10 месяцев назад

Is there tutorials available for mathjot?

@BrendanHasty 10 месяцев назад

Hi Deepak, there are some quick tutorials, more to come. Did you try it out?

@DeepakKrishna11 10 месяцев назад

@@BrendanHasty sorry not yet , but will do.

@yanndoffay-mancienne6275 10 месяцев назад

Respectfully, how is mathjot different to mathcad?

@BrendanHasty 10 месяцев назад

The ability to insert premade calculations "Jots" and how the variables are integrated makes it. This allows you to speed up any assessment and is extremely powerful. It is also in the Cloud. With its unique interface and feature set it really set it apart.
