Thank-you again SlideRulEra,
I was starting to think along similar lines myself. using very accurately established circular screed rails; possible using curved steel; taking time to set them up properly and screeding radially. 385m3 is a lot to pour in one day and achieve an adequate finish...
Hi IRstuff,
Again than-you for your interesting and informative input.
You are right to question the 200m building project.
From my simple trigonometric model, assuming the earth is a perfect sphere,(which it isn't),the earth drops off the tangent 3.1mm at 200m; with the earth radius 6378.1...
Hi IRstuff
Thank-you for your input.
I am confused by GPS coordinates and I have not found a source that will explain exactly what they are and how they
relate to each other.
I go back to the days of theodolite and tape; before electronic instruments were the norm. So I like to get a solid...
Thank-you SlideRuleEra
Your comments regarding the construction tolerances due to the radial rakes are very informative and extremely relevant.
Your comments regarding the number of bays are also accurate; certainly not a preferred solution; as I stated in my previous post.
As you say I will...
Thank-you for your reply and your ideas, Bridgebuster
The pour would probably be with a concrete pump and start from the base.
I am attaching a photo of a similar structure but the one I am doing is much larger and steeper: 1 in 6...
Hi
GPS V PLANAR CO-ORDS
Does anyone have a good source, preferably free on-line, simply described to explain "exactly" how GPS co-ords work and relate to each other.
I am thoroughly familiar with planar co-ords and have controlled many construction projects with them; before the advent of...

Hi
WASTEWATER CLARIFIER
I am looking at a wastewater clarifier. The concrete slab structure is about 35m in diameter, 400mm deep slab and a slope of 1 in 6.
It is an inverted cone shape and I am looking for ideas as to how best to pour it?
Has anyone done one of these before and how did you...

Hi
The bars I am referring to are not main structural tension /compression members,which are continued into the column; for
obvious reasons. The 'stiffeners are 12mm bars whích have been specified in the side of the beam to improve torsional resistance.
If continued into the column they will...
Hi,
DETAILING OF STIFFENER BARS (SIDE STEEL)
I am currently detailing continuous beams to the ACI codes.
Previous answers to questions I have asked on this forum have been enormously helpful.
I am trying to find justification to terminate the side steel stiffeners short of the columns; due...
Hi
POSITION OF RE-BAR COUPLERS - ACI CODES
I am using re-bar couplers in continuous beams. I am trying to find justification for where they are positioned in the
ACI codes but without success. I have tried 318, 315, 439.
The general concensus is that they should be staggered; top couplers...

ACI RE-BAR SPREADSHEET FREEWARE EXCEL - AMERICAN
I am looking for a freeware Excel program similar to "Barshed 8666" but for American ACI schedules; compatible with Windows 7

Hi Eng-Tips
I am looking at the simplified method for the curtailment of reinforcement BS8110 figure 3.24
Using these simplifications does one have to add a development length of 40-50xdiameter
or is it already included in the simplification
Please advise
Yours sincerely,
