    How to Calculate Punching Shear of a Hollow Concrete Column on a Reinforced Concrete Slab?

    @KootK the diameter is 102mm and I'm not sure if the piles have steel caps. This is why I'm asking because if they did, I wouldn't consider them "hollow" @NedGan 76 I'm not sure that's a correct analysis. The overall area of contact is now much less than if it was solid. Are you sure about...

    How to Calculate Punching Shear of a Hollow Concrete Column on a Reinforced Concrete Slab?

    So I'm basically asking what is supposed to be my "loaded perimeter" The Problem: Using Micro Steel piles embedded in concrete cap. I want to ensure that the (upward) reaction force that the piles would have won't puncture the concrete. So that's a punching shear calculation. The only problem...

    Where can I find the basic rules of structural systems? (e.g. when to use Mom. Frame, Br. Frame etc)

    Ok so this is a bit of a n00b question but can someone direct me to a resource or book that explains clearly when to use certain structural systems? I don't specialize in structures but I can analyze them and design them (following the codes isn't that hard) What I often don't know is WHY I'm...

    Contractor Installed Filter Layer without Geofabric...how much time do I have?

    The earth on the landward side will constantly drain into the sea. The sea through wave and tidal action will constantly mobilize the sediment behind the filter stone

    Contractor Installed Filter Layer without Geofabric...how much time do I have?

    Thanks slide rule...but wouldn't the fines wash through the filter stone anyway?

    Contractor Installed Filter Layer without Geofabric...how much time do I have?

    Hi there, Another colleague is doing a road widening work on a coastal road. They installed a temporary Revetment in order to prevent any interaction between the sea and their construction. When the road is widened, some of the new highway section would be very close to the shoreline...it's...
