Fake Engineering!
We pride ourselves on doing the job right and often find ourselves correcting over the top engineering and what we call #fakeengineering
Hooke’s Law Ignored:
These steels to take extra roof loading cannot take any load
1) until concrete beams shear at face of columns to strain the steel (dry-packing not enough!) But concrete does not fail in shear at a face so these steels can never take any load.
2) Neither do the bolts transfer load into the steel because they are in standard 2mm clearance holes.
Hooke’s Law Ignored II:– An alteration to a Grade 1 listed building.
As the propping was removed before the columns were installed, the beam reactions are already in the concrete facings so the columns, not ‘strained’, do not carry any of the load to the bottom (identical) 2x158kg/m UC’s of the box frame, rendering it pointless! And who thinks the 250×150(correction, not 100) RHS’s have to be laterally restrained like this?
Is this the greatest example of a Pointless Box Frame or has anybody else seen a better example? Not to mention the ‘criminal’ (as unnecessary) removal of Grade 1 Listed Building fabric. Another where I was out-voted by engineers, not out-thought.
Further note: I just noticed the tails of the joist hangers are not over and behind the wall plate!
