Hi Everyone,
I've got a steelwork repair design where we will be overplating some corroded steelwork.
The proposal I got have an existing Channel Beam of a size 7"x3", and we are attaching a 125x65mm channel to the middle.
The design proposes a tapered steel washer plate to be installed to...
Hi All,
I am currently working on a project where there is a temporary works required to support jack arches for a slab. The only viable option that is fast and cheap at the moment is to support the jack arches using a timber centring. There will be a scaffold platform up where they can utilise...
Hi Everyone,
We did a scaffolding design for a building to enable some works to be carried out at the roof level. Basically they need to create a structural opening for a new hatch and they need to remove some of the existing concrete from the roof.
The scaffolding platform under the roof is...
Hi Everyone,
Is there anyone from UK or Europe that has done temporary works design before? I am currently looking for a standard which would state that for a temporary prop and for a temporary loading (that we know the exact weight), can we reduce the Safety Factor? Typically safety factor for...
Hi Everyone,
I made a post yesterday but I wasn't very clear of the details for it so I thought I put another post with more details.
I am basically looking to assess an existing slab that will have a cantilevered end. We don't have any archive information for the slab and there are no...
Thank you for your responses. Apologies for not being more clearer on this. This is for an assessment of an existing structure. Currently we do not have any archive information or any surveys so I just wanted to do a quick check for the section assuming it to be plain concrete (worst case)...
Hi Everyone,
I am currently trying to analyse a section which is unreinforced concrete. I have attached below a sketch of the thing I am trying to analyse.
I am not sure how to go with this. I've got a load at the top which will create a bending moment at the interface of the section, which I...
Hi All,
I am currently working on a project where I need to assess the cast iron shaft linings (rings) for a vertical load of 14kN.
Basically the beams are sitting on these cast iron rings that has a 100mm bearing and are 25mm thick (see the images below).
The shear force from the beam is...
Hi All,
I am currently working on a steelwork repairs project for a cable shaft. The idea is to cut the ends of the beams where they have significant section losses and splice a new section in where it is going to be cut. I have attached a drawing and a photograph below just to give some idea...
Hi,
I am currently working to strengthen an existing floor slab where new heavy equipment will be installed on the floor above.
I have attached the plan view of the area below for reference. The 3no. beams shown are actually not supporting the slab and they are there to only support the high...
Unfortunately, I am in London and the client does not want any welding on site (this is a cable shaft and they consider welding to be a huge site hazard).. Usually in the UK welding is barely allowed on sites..
