AS3600 CHANGES: SETDOWNS IN 200 FLAT PLATE SLAB FAILS FOR ADEQUACY IN FIRE CASE

The “new” Australian Concrete code AS3600 was released in 2018. Although we are over three years past its release date, we are only now starting to see how Structural Engineers have interpreted some of the AS3600 changes. A quirky and often missed change to AS3600 has been the interpretation of how to treat the fire rating considerations for flat plate slabs with set-downs. Lets jump in and take a closer look…

SPAN TO DEPTH RATIO OF SLABS AND BEAMS

Structural Engineering design is an iterative process. Designs usually evolve from early stages (concept) right through to detailed construction drawings. Equally, Structural Engineers have different design tools to assist them in design at every stage in the process. One such tool is the span to depth ratio. It has its place in Structural design from concept phase and even towards the end of detailed design. So lets take a look at what span to depth ratios are and examples of span to depth ratios for slab and beam elements.

FOOTING DESIGN IN RAM CONCEPT

RAM Concept by Bentley is a popular modelling software for the design of suspended concrete slabs. It has both post-tension and conventionally reinforced design capability. However a lesser used function in RAM Concept is the ability to design mat foundations. This feature can also be used to design strip footings and isolated footings (or pads). For structures which are sensitive to settlements, RAM Concept is an efficient design tool to check your bearing pressure and structural design of your footing. So lets take a look at footing design in RAM Concept…

HOW TO SET UP GRIDS IN ETABS

Grid lines (reference grids or simply grids) are the glue that ties all of the engineering and architectural drawings together. They provide reference points which helps the reader identify the same locations on each disciplines drawing set. They are equally important for your analysis model to assist in providing snapping points. It also assists in coordinating your analysis model with the design drawings. So lets take a look at how to set up grids in ETABS…

WHAT DOES A STRUCTURAL ENGINEER DO DAY TO DAY

The recent changes to work habits due to lockdowns from COVID-19 has caused me to think about how the day to day life of a Structural Engineer has evolved over the last couple of years. Its also caused me to ponder how my 9am to 5pm routine and what I do day to day has evolved since being a graduate Structural Engineer compared to now being a Technical Director managing a team. So what exactly does a Structural Engineer do day to day?

WHAT IS A FLY BRACE AND WHAT DOES A FLY BRACE DO

In steel construction of sheds and warehouse buildings, there is a small element which has a huge impact on the overall performance of the building and its members. The aptly named fly brace can drastically improve a beam or columns performance due to its restraining characteristics. So what is a fly brace and what does a fly brace do? This article answers both…
