Hello friends, Today, we'll cover the shear verification of screwed steel-to-timber connections. Let's get into it.. The 4 Steps To Calculate The Shear Capacity of Screws According To Eurocode In general we separate 2 types of shear connections in timber design: timber-timber connections and timber-steel connections We already covered all verification formulas of the different failure modes of EN 1995-1-1 (8.6), (8.7), (8.9)-(8.13) in episode #23. You can check out the episode here. In...

Hi friends, Today I want to show you a bracing system of a steel staircase which wasn't designed very well. I was the checking engineer of the project. In Germany there is a second engineering office for most projects checking the structural design / calculations. But the checking engineer only has to check the ULS verifications to make sure that the structure dosn't collapse. SLS checks such as deflections are not part of it. In the following pictures you can see that the columns are...

Hi friends, Today's newsletter won't be technical as I wanted to share with you what I've been up to recently and how the development of module 3 is going. I haven't been working on Structural Basics stuff as much as I usually do for the last 3 months. The reason was that I moved to a new apartment with my girlfriend, I went on a few skiing trips, marathon prep and I got involved with real-estate for the first time. As you are reading this, I’m at the notary’s office signing the contract for...

Happy Wednesday friends, In the last newsletters we covered the tensile capacity of nails, screws, bolts and staples. In the next few episodes, we'll cover the shear capacity of these connectors. This is were the real fun starts as there are many different formulas. In this newsletter I'll give you an overview of the different shear connection types and in the next few episodes we'll dive deeper into the nerdy calculations. Let's get into it.. Overview of the different shear connectors...

Hello friends, Today, we'll cover the tensile capacity of stapled connections. Stapled connections are verified like nails according to EN 1995-1-1 8.4 (1). Therefore today's article will be more of a repetition as we have already verfied a nailed connection for its tensile capacity. Let's get into it.. The 4 Steps To Calculate The Tensile Capacity of Staples According To Eurocode The axial capacity of staples is calculated according to EN 1995-1-1 8.4. But EN 1995-1-1 8.4 (1) refers to EN...

Hello friends, I didn't send out a newsletter for 2 weeks and I am sorry about that. I was super busy moving into a new place with my girlfriend, while also being busy at work and with my marathon prep. This finally get a little bit quieter in the next weeks, so you will hear from me at least every two weeks, if not every week! In the last 2 episodes we covered how to calculate the tensile capacity of nails and screws. Today, we'll look at the tensile capacity calculation of bolts. Let's get...

Happy Wednesday friends, Last week I didn't publish a newsletter. A lot of stuff is happening at the moment. Work is busy as usual, I've met up with a few engineers from Munich that I've connected with on LinkedIn and I am about to move into a very nice apartment with my girlfriend. So the newsletter will probably be biweekly for the next few weeks. Hope you understand. Today, we'll look into the tensile capacity of screws. Let's get into it.. The 4 Steps To Calculate The Tensile Capacity of...

Happy Wednesday friends, Today, we'll get started with the design calculations of timber connections. In this 1st article, we'll cover the tensile capacity of nails. Let's get into it.. The 4 Steps To Calculate The Tensile Capacity of Nails According To Eurocode The axial capacity of nails is calculated according to EN 1995-1-1 8.3.2. According to EN 1995-1-1 8.3.2 smooth nails shouldn't be used to resist permanent or long-term axial loading. This means nails should only be used for...
