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...

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...

Hi All, I need to check a connection for a steel beam that will be cut at its end (300mm from the edge). New beam will be installed which will be back to back channel sections (180x75PFC). These are going to be spliced together at the web and bottom flange (top flange splice avoided due to site...

Hi All, I am currently designing a splice connection for a beam that is going to be cut at its end where a new section will be attached. I have attached an image of the proposed arrangement where the beam will be cut and the new section will be installed. At this figure, it shows that the...

Hi All, I have a problem where I want to calculate the shear flow in a built up beam where an existing beam will be strengthened by connecting another section to it (in this case the 7"x3" channel will be strengthened by connecting 125x65mm PFC section). See the figure below. The proposal is...

Hi All, I am trying to carry out a calculation for a transportation arrangement of an equipment in a plant room. The equipment we have is a transformer and it is quite heavy (~11 tonnes). The proposal from the contractor is to use skates to undertake this. They are proposing to put 2no...

Does anyone know how to carry out a design check for a splice connection for a PFC (Channel Section) connection? This is not given in the Eurocode and no software in our company has the capability of carrying this out. Curious to know if anyone has any experience with designing splice to a...

Hi All, I have described the problem in a video by sharing my screen as I thought it would be easier to show and explain that way rather than just typing here as it might get confusing. I hope someone can assist or come up with an alternative solution to this...

Hi All, I am currently working to provide an overplating for an I-section that is a historic section of 4"x3" RSJ. As you know, the historic sections have curvature between the web and the flanges (around 95 degrees). See the screenshot below for details. The beam that I am dealing with has...

Hi All, I am currently working on a project where an existing PFC channel (7"x3") is going to be cut due to complete section loss to its web (see the attached image below). The section is going to be cut 400mm from the support location, and the proposal is to provide a new steel section and...

Hi All, I am currently working on a steelwork strengthening project where the aim is to install repair plates to the existing steel beams at a cable shaft. This is a historic structure and over time, the steel beams have severely corroded causing section losses to the flanges and the web of...
