    PD5500 G2 - Local Loads on Nozzles / Branch Lines

    Yes, I agree that the reason that the factors are there is due to considering a line load as being applied as an area distributed load. However, I am still uncertain as to why they write the equation as "φ1r/Cx + Z — Cφ/Cx" - as "φ1r/Cx = Z" would it not make sense to write the equation as...

    PD5500 G2 - Local Loads on Nozzles / Branch Lines

    Thank you for the reply MrPDes Like you, I find the statement quite confusing indeed. While I can understand that it is a similar approach in the "Suggested working form G1", and described in G.2.3.4 b). This is for applied moments rather than applied radial loads. Thus I'm not sure how valid...

    PD5500 G2 - Local Loads on Nozzles / Branch Lines

    Hi EnergyMix Thank you for taking a look at my post. Yes, the first one is a Z. The confusion that I have is due to the initial formula that defines 'Z' as equal to 'phi * r / Cx' So why then use a formula that includes both 'Z' and 'phi * r / Cx' rather than just '2*Z' I feel like I'm just...

    PD5500 G2 - Local Loads on Nozzles / Branch Lines

    I'm trying to put together a sheet for PD 5500:2012 Annex G2, and I've a few questions regarding the interpretation - first of all: Section G.2.2.3.2 states that 'phi * r / Cx = Z' and then further down states that the value 'phi * r / Cx + Z - Cphi / Cx' shall be substituted to determine...

    Pile Impact Force During Insertion into Pile Sleeve

    We are considering the design of a subsea structure that will use pin piles for permanent foundations. During the pile installation into the guide cone, assume the pile impacts onto the ‘cone’ plate of the guide. A vertical and lateral impact force will result. How is the initial impact force...

    Creating Steelwork sections using Planar Shells?

    Thank you for the response Corus, Going even more fundamental than this... Would you look to make it using the following methods :- 1. make each web and flange seperately as parts, then bring them into an assembly. Thus for an I beam, you'd have 3 "parts", and a 4 sided frame would...

    Creating Steelwork sections using Planar Shells?

    Does anyone have any tips for methods to use when creating steelwork sections? I tend to end up with a lot of parent child problems when i come to try and modify the structure at a later point. If there's any online tutorials or tips for this, it would be greatly appreciated. Mikey
