. Thanks for additional comments human909.

OK thanks human909, understand given the complexity. Will have to figure out what to do with excitation and fatigue.

Thanks for responding human909. This is a new design and I don't have a feel if it's a problem or not. Was hoping for practical examples to illustrate what's done in design, understand there is difficulty in determining if quaking is an issue.

Hi, just wondering what people have done for design of bin and structure, as it relates to silo quaking. BS EN 1991-4 mentions it but says standard is limited for this. Failures have occurred, recall reading that in one instance failure occurred after one week of operation. Wondering what's...

Thanks for the additional comments. It is difficult to come up to speed on this as there is very little prescriptive information out there.

Thanks for responses. azcats, I believe bolt orientation is typically normal to face. human909, the embedment length is of the order of 1m to 2m, Geotechnical Strength Index is 1, Young's Modulus 15GPa.

For a structure supported on rock, which experiences shear load only, is there a design method available for design of rock bolts. The steel structure would be supported on either pedestals or a slab on top of the rock. All of the literature that I've come across so far only deals with tension...

Thanks for comments. Just to be clear, regarding last 2 posts, the case considered is for beam overhang past another member with and without partial rotation restraint (and with load at top ... destabilising). The effective length is 5.0L and 7.5L respectively from BS 5950-1/SCI P360. AS 4100...

Thanks Lomarandil, the comments above assist. Unfortunately cannot design out the condition in this instance. Understand that 2L is often correct ... for the case with a cantilever with a fixed base (restrained laterally, torsionally and against rotation on plan), AS 4100 agrees with BS...

In considering the capacity of a cantilever I-beam in bending, I looked at the following standards: AS 4100, BS 5950-1:2000 & SCI publication P360. Could anyone shed light on the following questions. Assume case of a cantilever segment extending past another beam, with partial torsional...

Ok, thanks for responses.

Has anyone come across lateral deflection criteria for bulk handling machines such as stackers, reclaimers, trippers, etc. This is to check supporting structure to BS EN. Is it the norm that deflection from machine loads only are considered, or wind load as well. Does requirement come form...

Has anyone come across some worked examples for deflection/rotation checks for concrete piles. Piles are integrated with tie beams for information. Looked at Pile Design and Construction Practice from Tomlinson and Woodward. In page 346, mention is made for assuming 50% inertia relative to...

Thanks for confirming.

Thanks HTURKAK. I presume this would be for ultimate loads, such as a storm wind event?

Thanks EireChch. Have you come across any publicly available criteria or specification that could be used in a calculation.

I was wondering if there's a reference for accepted lateral deflection at top of concrete pile, either bored or CFA, pile head is approximately at ground level. Assuming it's dependent on type of structure supported, possibly it's height. For reference structure supported is a steel building...

Thanks for response JLNJ. Can you please explain further on "force the entire structure to act as one unit".

Thanks HTURKAK, the assumption will be for a pinned column base, and also top of pile is pinned, so the moment is supposed to be transferred from pedestal into tie beams. Only thing is, without the experience I'm wondering why I don't see much mention of this load path, after a reasonably...
