I am sure someone has done this exercise.
For beams supporting existing cavity walls, say about 5m long for instance - how does a 203UC46 with 290 x 10 plate welded on top compare in price with a 254UC73 plain beam with no plate ? Plate for picking up wall overhang only, not considered for any...
We frequently get asked to size beams over bifold doors. What is a typical weight/m2 for these & a limiting deflection under load of door plus any live load over (eg roof over)? Thanks
I've been asked to calculate an overturning load on a mobile structure that will have windbreak mesh on it. I see it quoted as 50% or 60% reduction. Would this be a reasonable approach to say an overall Cp of 0.5? Has anybody any experience of this or know where there are any actual design...
I am currently looking to strengthen an existing RC beam & am considering plating the underside. Looking at the concrete, existing steel & new plate composite action what would be the correct way to consider the shear connection between plate & concrete? If using the standard FAy/I type of...
I am currently looking at bonding steel plates to the sides of a concrete beam to transfer shear across an opening to be cut through the mid-section of the beam. Although adhesives available give around 10 N/mm2 shear, the ultimate value of shear at the interface appears generally to be taken as...
Has anyone any references (or thoughts about) the effect on the slenderness ratio if the tension flange only of a beam is restrained? This seems to be largely ignored in UK codes but is quite a common situation in lightweight structures. The only reference I have seen has been in the Canadian...
Hi All,
Does anybody know where I could download a copy of a programme to work out the above?
There used to be freebie discs given away by manufacturers of insulation but these appear no longer available....
Yours in anticipation. M.
