LATERAL TORSIONAL BUCKLING AND ITS CAUSES

Lateral torsional buckling (LTB) in beams is a phenomenon that all Structural Engineers should understand. From what it is, what causes it and how to prevent it (for a list of other things Structural Engineers should know take a look at the article at THIS link). If you are a Structural Engineer and don’t know what lateral torsional buckling is (shame on you!) fear not this article covers everything you need to know in relation to lateral torsional buckling, so lets dive head first…

TYPES OF PILE TESTING AND WHY THEY ARE NEEDED

The foundations of a building are arguably the most important part of the design. After all, they support all the structural elements which are built above them. It is important to ensure that the constructed foundations are free from defects and able to support the design loading. This article will dive into the types of pile testing and why they are needed on building projects.

CONSTRUCTION JOINT IN SLABS

Due to the nature of concrete construction and how its formed on-site. Concrete buildings need to to be constructed in portions and stitched together. The result is much like a patchwork quilt of smaller components coming together to form one larger entity greater than the sum of its parts. What allows this segmented construction to occur are construction joints. This article takes a look at the construction joint in slabs in particular…

PILE FOUNDATION TYPES AND THEIR BENEFITS

Foundations can come in all different shapes, sizes and construction materials. A very diverse foundation system is the pile foundation. Pile foundations are used throughout the globe to support structures of all different scales. This article will take a deep dive down the rabbit hole and explore all the different pile foundation types and the benefits of each…

SHELL VS MEMBRANE, WHICH ONE TO USE IN ETABS

ETABS, developed by Computers and Structures Inc. is a powerful 3D finite element software for the design and analysis of buildings. It provides Structural Engineers with a powerful tool to model both simple and very complex structures. The user has the flexibility to design “stick” or “frame” elements (such as beams or columns). There is also ability to model shells or membranes for slab and wall elements. But what’s the difference between a shell vs. membrane element? and which one should you use in ETABS? Lets take a closer look…

WHAT IS A TRANSFER BEAM IN STRUCTURAL ENGINEERING

It strikes fear into the hearts of Structural Engineers. It goes against all logical load path theory. It is a counter intuitive way to transmit vertical load from your building to your foundations. But in some cases it is a necessity. I am of course talking about the transfer beam. But what is a transfer beam and what considerations do Structural Engineers and contractors need to take in the design and construction of transfer beams? Lets take a look…

WHY DID THE WEST GATE BRIDGE COLLAPSE

It was one of the worst industrial disasters in the History of Victoria Australia. The ripple effect of this event changed construction and bridge design globally in the early 1970’s. This event was the collapse of the West Gate Bridge in Melbourne Australia. Following this disaster there were a lot of valuable lessons learned in the construction and engineering industries. Lets take a closer look as we ask… why did the West Gate Bridge collapse?

WHAT SHOULD ALL STRUCTURAL ENGINEERS KNOW

Imposter syndrome refers to an internal belief that you are not as competent as others perceive you to be. Your career journey in Structural Engineering can be filled with ups and downs which can knock about your confidence. Sometimes its good to take stock and reflect on exactly what you have learned and achieved in your career. If your feeling imposter syndrome creeping in, have a read of this article where we ask, what should all structural engineers know?

HOW TO CHECK IF YOUR ETABS MODEL IS CORRECT

There’s an old grey-haired engineer in every office who talks about FEA models and “rubbish in equals rubbish out”. Today’s analysis software are very advanced and allow Structural Engineers to design truly complex buildings. This means that the quintessential “black box” of analysis is not only alive and well but potentially getting blacker, and larger every day. So how do you check if your ETABS analysis model is correct or not?
