Hi all,
I'm trying to work out the average/85 percentile reaction time for drivers responding to a green light at a set of traffic signals.
My hunch says about 0.7 seconds and google seems to verify that, but I can't find any 'accepted' time in traffic guides i.e Austroads/RTA/Roads ACT...
Hi,
Would someone please explain how to use table 3.3 (minimum queue lengths at a car park with control points at entrances) in section 3.4?
I'm working on a carpark with 1800 carspaces and with less than 75% in-flow during a peak period (about 500 cars). The code says the first 100 cars: 3%...
Hey all,
I've been asked to design a 700 long by 300 wide column (4.5m tall) with a 150 diameter down-pipe cast in the middle. This scenario seems a little odd to me but hey that's architects. Anyhow, I have no problems with do the basic moment/axial analysis and checking the reduced web...
Hey all,
Does anyone have any good references on how to analyze a concrete beam with a pipe cast into it? The pipes run the full width of the beam, perpendicular to the span.
The Hydraulics guy wants to run 5 100mm diameter sleeves through a concrete beam at 150mm centres, 200mm from the...
Hey,
Does anyone have any decent texts, papers or guidelines for designing HOTTTTT steel beams? I'm talking 300-500 celsius and changes in temperature will be about the same magnitude.
Thanks
Hey, sorry if this is been posted before I did a quick search and couldn't find anything.
Where does the idea come from that a footing is considered structurally safe when the resultant of the moments is within the central third of the footing? Can anyone recommend a decent text/paper that...
Hey all,
Does anyone have any references eg state legislation, Australian standards, workcover etc that I should be aware of when designing CCLPS?
I've found this one...
Hey,
Hey could somebody please post a property table for steel sections from the good old imperial days? Dimensions for a 12 by 5 tapered flange beam would be awesome.
Thanks,
Paul
Hey Everybody,
Does anyone have any design guidelines that includes fire-resistance performance? I'm currently using a 2002 Onesteel (Australian steel manufacturer) paper, but it's not very useful for any columns taller then 2m.
Thanks,
Paul
Hey everybody,
I refer you to table 5.6.4 note 1: "The first order eccentricity"... blah blah... "e/b has been taken as <=0.025 with emax = 100mm". I take it this clause limits the table usage to columns with tiny moments and high axial loads.
For example I'm designing a 600 by 300 column...
Hey all,
I'm doing an extension on a building that requires a courtyard/pathway thing installed at the 'basement' level.
However, that requires excavating around an external slab on ground which is housing mech plant that must remain operational during construction. The slab is only 100mm...
Hello,
I was told to design some purlins by a senior engineer that must be Stramit Z250-15 at 1500 centres. These things are spanning 11m and after a few checks I find they fail under the wind pressure from AS1170.2(the Australian wind code), no big surprise. I go back to the engineer and...
Hey,
Could anyone please recommend and provide a review for a decent concrete analysis package that allows detailing of PT, reo and is compliant with AS3600?
Thanks,
Paul
Could someone please provide a reference to some literature or advice on the use of acidic/low pH epoxies in concrete to anchor steel bolts.
On a project currently under construction the builder wanted to use a different epoxy to the one I had specified. According to the manufacturer (They...
