One of the possible reasons that the UK Steel framed building industry has a major share of the building frame market is that the Contractor carries out all connection design and detailing for the steel frame structure........ saving on the Consultant design time and fees.
The Concrete framed...
Existing 200 thick ground bearing slab in a cold store, with high bay racking system, has been laid as a large area pour slab. There are sawn contraction joints at 6m c/c with the main contraction / expansion joints located at 40m centres.
Due to lack of business the cold store is...
I am looking at the option of specifying diamond grinding for a newly laid concrete slab surface. The alternative is to put down a screed on the slab, but this extends the construction programme. The screed will then require time to 'dry' to recieve the intended finishes.
I read somewhere that...
The design for a basment under 5m head of water called for "ground anchors" to resist the buoyancy forces. The contractor has proposed "tension piles" using 40mm GEWI bar. The codes require "double corrosion" protection for ground anchors but are not so stringent...
70mm (2.5") of make up floor screed (sand, cement, 3mm aggregate) is proposed over ESWA underfloor heating cables (40degreeC). Is anti crack mesh necessary in this screed?
Should this mesh include allowance for additional temperature steel as the screed will experience hot and cold...
We have a metal decking flooring system with 130mm thick in-situ concrete slab, spanning on to beams at 2.5m-2.75m centres. The slab weighs 2.4kN/sqm, +1.5 kN/sqm finishes, and the live load is 6kN/sqm.
We are happy with the Natural Frequency of the steel beam, but would like to know what is an...
My personal experience has shown that a lot of emphasis is placed on Construction Project Management, with little importance assigned to planning of the Design activities.
I believe that every project is created twice, Mentally at the design stage and Physically at the construction stage, both...
Many warehouse ground floor slabs on geotechnically poor sites are being constructed on piles due to the high specified loads of 50kN/sq.m being set in the Clients brief. This leads to expensive floor slab, or even shelving, ironically, of the whole project.
I presume that the basis of this hign...
