DWHA I absolutly agree.(with conditions) but I dont have access to ACI being an american code.

of course would have thought that is obvious. You are not considering the steel per say, just the confining effect of the bars.

it is plain, or only has very nominal. It is ground supported. The BS codes do not calculate just concrete, the allowable figures take into account the dowelling action of the steel. In the equation is an AS value. If this is 0 the answer is zero. You could size so that the entire footing is in...

my code deals with RC conc. i.e combines the dowelling action of the bars with the concrete. As is included in this relationship.

not US based sorry.

does anyone know how to prove punching of a column on a unreinforced or 'lightly' RC slab. ground supported?

i would generally agree but to me a baseplate in US is a base plate in UK i.e. flat piece of steel. If its not failing in US under x load in US/Australia then it won't fail here regardless of how I prove it.

cheers asinxth. in the equation what is b1. i.e what is the moment in figure 5.12.8 a? bolt spacing 300 long ways 200 short ways? not asking for you to giv me answer but what figures are where?

I haven't a scanner available. Its a 610 UB column. Uplift applied with shear at braced bay. Bolts inside the column flanges 300 apart and 200 apart in other direction (4 no).

bolts inside but looking at it generally really. Can picture the mechanism but how to do a quick hand check?

checking baseplate bending, can do it for bending but not simple supported with axial tension (uplift).

sorry Uk based. Unless that is freely available

how do you confirm capacity of simple column baseplate in uplift conditions. Uplift dived by 4 bolts (plus any prying force). Baseplate? thanks.

well I'm talking about liquids in general but i see your point. It seems a strange sudden jump from 35 degrees max to 200 max. But yes certain industrial applications do go over 50.

what temperature of liquid is considered to be ok for standard designs. I am looking at BS8007 which states a temperature of approx 35 degree celcius. The equivilent Eurocode which we are now swithching to has a range of -20 to 200 degrees celcius. Why the massive disparity? 8007 is a dated (now...

not sure what codes are applicable to you. Possibly the docks will have their own standards for replacing rails. For instance in UK here in freight yards it might be governed by one the operators specs. EWS (english, welsh and scottish railways) are one operator. I know they give a maintenence...

use appropriate steps that any structural engineer would use to verify or not. If you dont know how to do this find someone who does or ask for help from an suitably qualified collegue. To ask such a general question on here is not the way forward as there are so many things to consider. To...

am I reading this right, placed in beam running along the length of the beam?

I would say your h will be actual thickness minus bottom cover and the eff d is h minus top cover minus half diamater. Since the concrete section starts at the top of the pile head for hogging. This is only applicable for a very small region however around the pile so I would not deduct it and...

what typical coatings does anyone know of for dealing with concrete where chemicals could spill? acids etc.
