Nothing at all to do with sheep...
A while ago (like over a year now), I added the New Zealand concrete design code to the excellent concrete-properties repository. I had COVID and got really bored, and actually ended up completing something! I’ve realised I never posted anything…
Timber, what can I say…. well probably if you could be bothered listening you’d hear a lot of unintelligible colourful mutterings if you get me started and I’m having a bad day on the timber design…… Sometimes I’m a fan…
No python here, sorry to disappoint. I thought I’d post some useful AISC videos which reinforce all the rubbish I’ve been talking about (and lots of stuff I barely touched on) in this series regarding the strengthening of members. Some…
In this part we visit adding angles nested into the web/flange interface. This is kind of a good means to increase both the bending and axial capacity of a member. Though it results in a bucket load of welding, it’s…
In this part we consider adding a parallel flanged channel (PFC) or I-Section to the flange of an I-Section. This configuration is used quite often for crane rails (for adding a channel) to deal with lateral thrusts from a runway…
In this part we cover adding a tee to the flange of an I-Section. It’s a good way of increasing the bending resistance of a beam or stiffening it up if you’re improving the deflection performance as there’s a good…
In this part we cover slapping some plates on the sides of an I-Section before unleashing the welder to make some fire. But first I wanted to touch on an important aspect, in the previous post we discussed the strengthening…
In this part we cover welding a flat plate to a flange. Firstly, a couple of housekeeping issues….. Most people (and commercial software) approach the calculation of properties for built-up shapes by slapping a plate hard against the section resulting…
Over on Eng-Tips forum, the question seems to come up quite regularly regarding the calculation of certain steel member section properties when you’re in the situation of having to strengthen a member with added reinforcement. Usually, the question is related…
Well, this post has been a while coming (since Part 9), not because it took a lot of work. Quite the opposite, more regarding a lack of progress on this project in the last few months! Life has a way…
Part 9 – Verification Part of the verification process in development of a spreadsheet or software tool involves what I like to term the process of idiot proofing. Some end users are considered as potential idiots, asking yourself to think…
Often in engineering you need to make simplification in analyses that make your life easier, often applying some judgement based on experience that involves some simplification in the analysis of a structure for example. Sometimes you do this in the…
This blog post is inspired by a recent post which I responded to on the EngTips forum. The question was related to finding the warping constant of back to back cold formed channels. The poster was querying the validity of…
When setting up the WordPress software on which this blog runs, I wanted it to be secure, who wouldn’t. I mean nothing can be guaranteed as being 100% secure, but we can certainly do our best to address known weaknesses…
Part 8 – Documentation, the Necessary Evil Love it or hate it, I’ve already decided documentation is required so you are stuck with it. Code comments and docstrings aside, part of the planned documentation is this series of blog posts…
Part 7 – Documentation & Verification, Better Than More Integration? At some point in any projects life cycle you should start thinking about the need for documentation and verification. This post and probably the next few will be dedicated to…
