The 9th International STESSA Conference on the Behaviour of Steel Structures in Seismic Areas took place from February 17 to 19 in Christchurch (New Zealand). This conference, which is triennially held, is organized by the Steel Construction New Zealand Incorporated (SCNZ) in cooperation with the University of Auckland, the University of Canterbury and the University of Naples. Like the previous STESSA Conferences, the University of Canterbury was selected to host this event.
New year – new luck! This also means: a new attempt at keeping the good resolutions we keep on setting for ourselves at the beginning of a new year. We admit: we usually revert quickly to old habits. But, aren’t we annoyed with ourselves? So, why don’t you put into action one very important resolution commonly with us? We’ll show you how you can make your workday healthier with only a few tricks – this will not only help you work more effective and motivated, but in the long run, your health will also benefit from this.
The Christmas season – the time of rest and reflection? Well… instead of love, harmony, warmth and a sense of well-being, many of us actually associate the pre-Christmas period with stress, deadlines and overtime. A pile of projects heaped up on our desk which, ideally, should be completed before the holidays. In our private life, Christmas parties, visits to or from relatives and preparations for Christmas dinner make schedules even busier.
But, let’s be honest: the greatest cause of stress comes from our desperate search for suitable presents. After all, we would like to get something "special" for everyone.
If this sentence makes you nervous – don’t panic! We are going to show you how you can still please your loved ones with only four days before Christmas, in spite of your long to-do list.
The term ATEX is derived from the French denomination "Atmosphères Explosibles" (explosive atmospheres): The ATEX Standard comprises the Equipment Directive 2014/34/EU as well as the Workplace Directive 1999/92/EC. In a previous article about the ATEX Directive we put more emphasis on general issues and theory. In this article we use the example of a flexible claw coupling to explain in more detail how this standard is implemented in practice.
Today, Locking Assemblies and Shrink Disks are standardized elements which provide a frictional connection between a shaft and a hub. They are not only capable of reliably transmitting torque, but of axial and transverse forces as well as bending moments, too. Oskar Peter is the father of the Locking Assembly. He recognized back in the 50`s that a locking assembly, in contrast to a key, is able to transmit considerably higher torques, thus allowing the engineering of much thinner and shorter shafts.
The 17th edition of the biannually held EXPOSIBRAM took place from September 18th to 21st in Belo Horizonte (MG), Brazil. With a floorspace of 12.000 m², this exhibition is considered one of the greatest mining events in South America, gathering representives of government authorities, contractors as well as private organizations in the same place. EXPOSIBRAM also hosts the Brazilian Mining Congress, which is organized by IBRAM (Brazilian Mining Association).
This year, the 15th D-A-CH Conference, which is organized by the Societies of Earthquake Engineering and Structural Dynamics in Germany (DGEB), Austria (OGE) and Switzerland (SGEB) took place on September 21 and 22. September.
This gathering of experts is conducted biennially and serves both as the exchange of knowledge between seismologists and engineers and the presentation of current scientific findings and experience gained from field applications. In addition, companies operating in the fields of earthquake engineering and structural dynamics as well as manufactures of earthquake protection systems had the opportunity to present their application solutions in the foyer of the Bauhaus university.
In this blog article we are going to take a closer look at the API Standard 671 which specifies the requirements for special purpose couplings used in the petroleum, petrochemical and natural gas industries. This Standard has been developed by the American Petroleum Institute (API), which is not to be confused with the identical abbreviation used in the IT field (Application Programming Interface). Let's begin with a few details about the institute that gave the name to the API Standard.
Measuring processes unconsciously cross our daily paths more often than we are aware. Whether it is about scooping coffee for the coffee maker, the temperature of the coffee or the speedometer in a car - we encounter measurement technology everywhere. But, what is “measuring”?
A well suited definition is given here: “Measurement enables us to make statements about a measured parameter in relation to a unit of measurement”. Measurement technology allows the determination of parameters such as length, mass, temperature etc.
