Fibreglass feed bin moving in wind.

We have a 20 tonne Kirncroft fibreglass feed bin (10 metres high) that has loosened again in the storm .
It has pulled the 8 fixing bolts up a good centimetre allowing the whole structure move considerably in the wind.
2 options (a) just tighten down the bolts again (been done before).
(b)resite bin by 12 inches and use new bolts on plinth.

Can you get a piece of flat bar say 3-4” wide and atleast half inch wide over the base of the legs? If so drill a hole big enough to fit over existing fastner in a piece say 10-12” long and then bolt it with a suitable fastener to the concrete slab to gain extra clamp force, better still if you can get more than one on each leg

Resin anchors are very effective. Orbital Fasteners are good for the fixings and Ironmongery Direct good for the resin - we have used Fischer Vinylester Resin on a few projects.
 
Just seen this!
In my opinion it is no good waiting until bin is empty as it will be easier to blow over in gale.I have never used any chemical resin so I can't comment on that ,the only way I would do this is to make frame for each leg with extra anchor bolts
 
Is Sir loin in an area prone to strong winds??
I have been thinking what I said a few minutes ago..... if I was in similar situation I would consider burying girders in concrete 4 feet then fixing to corn bin legs

Buy 2 smaller, lower bins ?
Lost a 20 ton one here 10 years ago, full of organic poultry feed @ £400 / ton.
Box profile legs actually bent.

I often wonder how these stick it, perched up in the sky, its some bit higher than the other 2

Yes we are prone to strong winds and the bin is actually more than 10 metres high we have tightened the bolts for a second time and are currently making some plates to weld to the existing legs (4 legs 8 plates either side) and reading the thread going to now use resin to fix the bolts down. There will be 16 bolts when we have finished holding the bin down. Thanks for your replies. (y) (y)

Try putting a gusset from plates to legs aswell, but bolt it to bin leg with 1 x 16mm bolt, do not weld it to leg of bin

Just a thought, could new bins be put up the same way as a shed using cones and bolts in the concrete? No help to existing bins I know but maybe possible in exposed windy area's where new ones are going up

Why not weld??
1 x 16mm bolt 8.8 hardness, will be far better and stronger structural engineer than welding,
Welding can cause heat distortion, or weaken the legs, it's a fine line between getting penatration of the weld, and causing cracking at edge of weld to both parties, especially when each party is of different thicknesses, also the bin leg will most probably be galvanised or maybe but unlikely electroplated, welding will cause rusting at the weld point, and the area around it where it has been ground off to weld,
So my advice is to bolt it, not weld it to the leg of the bin

We have taken your advice and got some plates made to go over the existing bolt and 16mm rawlbolts fastened either side so we now have 16 rawlbolts holding the bin (have pictures but cannot get them off my phone for some reason) bin is 12 metres high and holds 20 tonnes of feed. Cannot get resin to fix bolts in and wanted it doing before next storm due tomorrow.
