5. NONLINEAR ANALYSIS OF MAT FOUNDATION FOR CHECKING UPLIFT-MAT/RAFT DESIGN COURSE

[@frankjames629]

Is there any way to design reinforcement for a non-linear case such as raft resisting hydrostatic pressures where dead weight from raft alone is not enough to resist the hydrostatic pressures and the weight of the level above (via columns landing on raft) is required?

[@khankaleem1841]

Sir, can you tell me which book you used for the load combination because you have shown us only 13 load cases but you put 25 load cases

[@smarth5x601]

Sir please explain why you have chosen nonlinear analysis type for uplift calculation, why you didn't go for linear analysis type? Thanks.

[@aquibqadirtunio4090]

dear do we consider superdead loads like backfill and finishes in this combination or only self weight of raft is considered for uplift check ? and when no live load is uploaded on foundation then what combination we have to use?

What to do if warning related stability came during non linear analysis

ভাই, ACI 318-08 CODE এ তো uplift এর combination গুলো পেলাম না, আপনি একটু screenshot দিয়েন

[@faribasalimi9397]

Thanks for the great video shared.Please explain why for each EQ load case in Etabs, 3 load case in safe created.Thanks in advance for your kind attention.

Bro, you're a hero

[@tanjirahmed4382]

can u please refer the book for load cases of mat. also here is only 13 combinations but you showed 25 in the model...

Have soil properties only compresion or compresion and tension limits thanks

[@AbhiCrux]

Compression only. Tension is not desirable.

How to decide strip width

[@sumitmaskey3295]

I didn't get one thing sir...150kN/m2 is the Allow. Bearing Capacity (i.e., with FOS) But I'm confused if the Soil Pressure shown in SAFE here is Allow. Bearing Capacity of Simple Ult Pressure as we haven't assigned any sort of FOS in SAFE. Looking forward for your answer sir... Because, In my design, Allow BC with FOS 3 = 220kN/m2 Mat area 48m x 48m The soil pressure shown has the max value of 600kN/m2 in SAFE. If I remember correctly, this soil pressure has not taken an account of FOS anywhere. THerefore, I checked the results 600..by diving by FOS ie. 3. IS THIS CORRECT?
