I am working on a project were we have to make a new connection to a pipe 16.5 feet below ground level. The pipe is beside a river with the underlying ground consisting of a free draining gravel.
The plan is to sink a shaft 15ft by 15 ft on plan using sheet piles and excavate down to the pipe...
Can anybody tell me if it is still acceptable to use British Standards that have been withdrawn and been superseded by Euro Codes.
Does anybody know for example the transition period from from BS8110 to EC2 for concrete? Must EC2 be used not for all new concrete structures?
I am working on a project using a secant pile wall as a temporary support to allow the construction of an underground tank built below the water table. The contractor has left some timber formwork trapped between the secant pile wall and the finished poured concrete wall. I have some concern...
I have been looking at a roof truss for the past few hours and I would like to get a few opinions.
The truss is a bow string arch which is popular for school halls where I work, Ireland. There are many example of trusses where I live that use only steel rods for the bottom chord. Some of the...
I am working on an oversea project in Africa that includes a number of Pre-Engineered Metal Buildings being fabricated by a steel building supplier based in Africa. The fabricator is using an American PEMB system from one of the US's leading PEMB companies. Someone on EngTips previously...
I have to check the design of an engineering who is analysing his structures on Staad Pro. I do not own Staad Pro but I do own Robot Structural Analysis which is supposed to be capable of converting and opening Staad Pro files.
I am opening the files in Robot as Staad Pro files and the...
I have been asked to look at what happens structurally to HDPE pipes buried in ground subject to heave.
The concern is that a leak in a pipe or from another source could cause the earth around the pipe to heave. The expansive heaving ground is 'Black Cotton Soil' which in this case can heave...
I have always used a rule of thumb that vertical joints in poured insitu concrete basement walls should be spaced at a distance between 3 and 5 times the height of the wall.
For example when a basement retaining wall is 10 feet high we would locate vertical construction joints in walls at...
I am currently checking structural steel fabrication drawings prepared by a leading American Steel Fabricator (World leading even) and the drawing are not to scale. I am in the UK and the project is in Africa.
I requested drawings to scale and was told that the fabricator does not produce...
Hi
I am doing quite a few retaining walls at the moment and the ground conditions vary. The project is very preliminary and I don't want to spend too much design time on it at this stage. I was wondering if anybody has quick design table for retaining walls. I have spread sheets but tables...
I have moved this thread from the geotechnics forum
My projects often involve undeground basements, usually for carparks of up to 3 underground levels.
My query is that as some of you may know BS 8102 recommends that water table levels for basement design should be as follows:
For basements...

I am working on a number of projects at the moment with very heavily loaded flatslabs which support up to 5 stories of blockwork building.These slabs are generally in excess of 600mm deep and are designed by F.E.M. Line loads from the buildings blockwork walls are taken directly onto the slab...
I am working on a building development in Ireland where I must provide a storm water atenuation tank in order to prevent flooding the Local Authorites drainage system. A flow restrictor at the exit of the tank will control discharge.I am using the Rational Method to access storm water runoff.My...
