In Australia we would only ever consider frame interaction on structures that have substantial floor elements (such as edge beams - normally in commercial buildings only). Most high rise residential structures in Sydney have very thin flat post tensioned slabs and hence the amount of moment that...

The Australaian Standard AS 1288-1994 "Glass in Buildings" states in Clause 6.3 "Sloped overhead glazing(including rooflights)"........glass used in overhead glazing at slope less than 30 degrees to the horizontal shall be Grade A safety glass"
Grade A safety...
As a facade engineer in Australia, my firm gets involved in quite alot of what we call "frameless point fixed glass". This type of a system is one up on the frameless glass systems using glass fins where by the glass is supported at its corners by patch fittings (commonly called...
I would be interested in finding out peoples views on the required live loads required for balustrading. Here in Australia (AS 1170.1) we have some quite onerous loading provisions which I am not sure always are practical or physically achievable. For example<br><br>For private dwellings...
Most steel fabricators and errectors normally provide tempoary bracing to columns and other steelwork during errection such to maintain the tempoary adequacy of the steel work. My question would therefore be why is it of concern?<br><br>As far as physically calculating the impact...
Does anyone know of any good sources of tech info into the strengthening of concrete slabs/beams through the use of epoxy bonded steel plates to the exterior surfaces. Are there any Standards in either the US or UK that describe this kind of strengtheing.<br>
<br>
Interesting observations, I must admit that in 15 years of owning and operating my own practice here in Sydney I have only had a few occassions where the quality of the supplied concrete is suspect. We have a few rules that assist this process.<br>
<br>
1. Our specification requires that the...
The Australian Standard AS2870 "Residential Slabs and Footings" gives guidance on the design of slabs on ground by Engineering principles. In particular taking into account load conditions such as edge heave and centre heave due to expansive clays and serviceability requirements. It...
Our practice in Sydney does use covermeteres quite extensively. We can hire them for about $110 AUS per day. It is noted that we only use covermeters for checking consitency of reinforcing from one area to the other. Yes the meter does give an accurate representation of bar location and a...
Further to my earlier post try this site for some US info.<br>

With respect to the strength properties I would expect that most stainless steels are manufactured to similar properties irrespective of Country of origin. I certainly know that the stainless available her in Australia (eg 304, 316, 2205 Duplex) is very similar to other materials available in...
A good sourse of technical info can be obtained from the Australian Stainless Steel Devlopment Association (<A HREF="http://www.assda.asn.au/" TARGET="_new">http://www.assda.asn.au/</A>). In particular their technical publication "Australian Stainless - Reference Manual" is a very good...
Does anyone know of any good references for the design of structural glazing systems. <br>
<br>
In particular I am interested in <br>

1. unframed glass walls consisting of tensioned truss assemblies supporting glass walls via patch fittings and "spiders" onto the rear face of the...
I think I may have an answer to my own question. <br>
<br>
One of my engineers has found a reference book with some published data on the drag resistance of flags. It comes from "Fluid Dynamic Drag" by Hoerner 1965 pp 3-25. This refernece quotes research done by Faithorne "Drag of...
I employ approximately 20 engineers and 8 drafstman here in my practice in Sydney. I agree it is a definite problem finding good ones. It seem to me that in Australia anyway that drafties are a real nomadic bunch and do not like to stay in the one place for long. We have found that one way of...
