Take it easy everyone... As seen in the images, the retaining wall model I entered does not provide the collapse factor verification. How can I get this verification solved through the slice method?? Or, I have not seen a condition/condition about this inquiry neither in TDY-2007 nor in TS 500. Do I have to meet this requirement? It would be healthier to have it provided, but I could not find anything about this investigation in the regulations and standards. Thanks for your answers and suggestions...
