    Crane Runway Girder to Concrete Corbel

    Hello everyone, Want to ask an advice. I have to design crane runway girder joint to concrete column corbel. I dont deal with cranes very often so I dont feel lot of confidence in my solution. Any advice/critique are welcome. Some years ago we designed a warehouse with light cranes (5t or 8t...

    Steel truss and concrete column connection

    On your sketch there are 2+2 anchors, why not 1+1 on the centerline of truss support node? My assumption is to get rid of pouring work at column top and just provide neoprene pad or just some levelling plates (if needed). Have to be easier. On the other hand, grouting maybe a nicer...

    Steel truss and concrete column connection

    The proportions and geometry of the joint will be changed, it was just a sketch from preliminary design. The main point I wanted to discuss was welding on 2 sides and how this may affect the joint itself. That`s a good point, I was thinking in a similar way. It may be pinned for truss...

    Steel truss and concrete column connection

    HTURKAK Truss bottom chord doesnt connected to the column so in my global frame model I use pin connection between truss and rc column. I dont need moment connection to my frame in upper joint (truss-rc column). KootK I agree with you that its not the best one, but very common solution here...

    Steel truss and concrete column connection

    Hi all, I want to discuss such type of connection where steel truss is welded to anchor plate installed on the top of concrete column. Steel truss is welded with fillet weld. It is considered that joint is rigid when truss post is welded around. My question is it possible to consider such joint...

    Deep beam support length

    Yes, there will be dowels. 1. It was precast wall/beam in the begining (we took this project over from another engineering company), but then we decided to make 2 first walls as CIS and beam is also CIS. Column in precast one. Wall thickness was 200mm, we are deciding now to leave it 200, make...

    Deep beam support length

    KootK Thanks for reply. We do not distrubute anything through hollow core slabs, its a ledge concrete beam there, so wall will transfer compression directly to beam body.

    Deep beam support length

    I have to design some deep beams (walls) in my ongoing project. I have a problem with determining appropriate length of support. I will attach a picture. Between deep-beam and concrete column there is a concrete beam for supporting hollow core slabs on first floor. What would you suggestion for...

    Slab on grade 19,5m*7,05m without any joints.

    Tomfh That is what I am thinking about, more reinforcement for upper layer and no joints. Bottom reinf according design loads. Yes, 1.3m is quite thick. We had 2 options: slab of thickness 200-250 everywhere (inclined part also) + some small "retaining walls" on long sides of inclined part to...

    Slab on grade 19,5m*7,05m without any joints.

    Hi everyone, My first post here, hope you can give me an advice. I have a slab on ground 19,5m*7,05m, on part of it is inclined. The thickness of slab will be 200-250mm on a flat area and 200-250 to 1350mm inclined part. Volvo F120 wheel loader will be moving on (from outside area to warehouse)...
