Thank you.
The founding material is weathered rock. Bearing capacity and elastic modulus are provided.
I will try to ask the geo consultant to provide subgrade modulus.
If it is not obtained, for simplified calculation what do you recommend? I was trying to treat it like a rigid plate and apply...
I am going to design a raft foundation for the core walls in FEA software but subgrade modulus is not provided by geo report. How do I analysis and design it without it?
I can use hand calculation to analysis and design like a pad footing but my question is how do I get the moment applied to...
Can anyone please tell me when it comes to moment curvature analysis why do we focus on the strong axis of the walls only? Don’t we need to examine the displacement capability of the wall in weak direction more? I understand that the moment in weak axis can be ignore but the point of moment...
Can you please further explain how this will affect the shear? I would expect the shear in the step increases when the stiffness of horizontal restraint increases instead of the rotation fixity?
Thank you Kootk!
The below replies are based on positive moment assumption.
I have seen 1.5D or 2D from many firms too but wondering if this is specified in any standards? I was looking at the paper "one way slab with large steps" mentioned in the reference that Manitou90 provided and they...
Thank you. I have checked the links you provided as well as the paper for large steps. However I believe that the 800mm step I have here is way too large compared to the 250mm steps in that paper although it is near the support instead of mid span. Is tie model mentioned in the links is...
Can anyone tell me how wide the soffit has to be for step downs in one way RC slab and why?
Also do you see any issue with the connection below?
Thank you.
