I was given a RCC Spreadsheet to do the RC Retaining Wall design which by any means will reduce the total design time as I do not have to do all the calculations manuallly.
However, before I can use the spreadsheet, I have to verify the accuracy and precision of the spreadsheet.
By using the formula and steps refered, I manage to find differences between RCC Spreadsheet and manual calculations.
As a result:
RCC Spreadsheet was more precise as it takes into consideration of all factors including:
Buoyancy Force (Cause by Water Level above the base of RC retaining Wall)
Cohesion force of base while calculating the Base resisting force for Sliding Check(Can be cancelled to be more conservative)
As a conclusion, RCC spreadsheet can be used to design RC retaining wall
