Hi,
Say I have 2-span band beams with same width and 1 layer of top reinforcement, 1st span is 15 bars while the other has only 10. Isn’t lapping of the top bars an issue?
The max deflection at the middle of the slab you are getting is the cumulative result of beam deflection plus slab deflection. Adding a column on both side at the mid span of the beams reduces the deflection of the beam and thus the cumulative result of the slab, which is the main reason that...
Thank you guys.
Can you please explain this a bit more?
I would like to model spring but I find it hard to assume the spring stiffness. What is the stiffness you would use? (ground floor to basement 1 is silty clay while basement 1 to basement 2 is basalt rock). The geo report doesn't mention...
I have this building that has two levels of basement and I want to assume the base is on the ground floor.
What I have done in my model is I include these basement walls in my model and at the same time I assign point restraint UX UY to four corner joints of my ground floor slab (shell element)...

Thank you for the textbook.

Yeah. P was not in that pic I uploaded just for clarity.

I will double check on the spreadsheet and see how it goes and will be back if I have problems. Overturning will be checked. I was concerned because like I said, some software simply...
Thank you.
So I had a look on the link and the spreadsheet you provided. However, the pad here has no rods to hold the tension so I believe it is a different scenario.
My thought is shown as below. Is this a correct approach or am I missing anything? I know the stress at the corner will be quite...
Thank you Celt. I will have a look on the link and the spreadsheet before I comment further.
Just a quick one. How do you analyze raft supporting core walls, which is quite common to be bi-eccentric loaded then?
I know how to analyze when resultant force is outside of middle third in one direction. But how do you analysis when the load is eccentric in both direction and at least one of them is outside of middle third? I tried to use software called TEDDS and it says it fails once it is eccentric in both...
