Hi, Anyone has an idea about this?

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...

Even with the slip critical condition the bolts should pass the design checks with 0.45-0.50 utilisation though..

There is no requirement for the connection to be slip critical..

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..

The issue I am having here which is not shown on the drawing is that there is another beam connected to the existing which is restricting the length of that splice section. Please note that the splice is not a plate and it is back to back angles connected to the existing, and it is only 300mm...

Hi SWComposites, This is true for a connection which is required to carry higher forces. But when considering having such a low moment and shear force, don't you think this would be sufficient?

Hi Dik, The neoprene is there to avoid bi-metallic corrosion due to cast iron rings touch the proposed steel. This was one of the requirements from the client. In terms of the bolt requirement, I proposed 4no. M16's as the Bending moments we have at that location is 7.18kNm and the Shear...

HI Dik, Thank you for your response. When the back to back channels move off from the existing beam, there will be a gap between them which needs to be filled with a ~8mm plate to act as the "web". Hence the requirement for those bolts. I know that 6no. bolts are excessive and over design but I...

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...

Thanks everyone for their valuable comments. Just for information, this is for a cable shaft where the applied loading is very minimal and at that particular location, the bending moment is around 6kNm which is quite low. That's why I was thinking to use this and use M16 bolts which should be...

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...

@CANPRO Ah I see your point. But just to understand, when you say the sections will share the vertical load in proportion to their bending stiffness, how is this calculated? Is it the moment of inertia ratio between two sections and just sharing it accordingly? i.e. if the moment of inertia of...

@human909 & @Eng16080 , thank you so much for your input. @Eng16080, when you say "I would determine how much vertical load needs to be resisted by the 125x65mm PFC" can you elaborate on that a bit? I have attached another figure below to show the connection detail on the elevation as well...

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 Desrtfox, No I do not know the centre of gravity and that's what I am looking to calculate using the position of these skates. I do have the exact position of the skates.

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...
