1 more than 120, reason is 1.3 cNc --0Modal content

simply take example of terzanghi eq. for strip footing & c-soil = C Nc + 1.Yd for circular footing with clay= 1.3 C Nc + 1.Yd as you can see there i 1.3 time higher cohesive resistance so higher capacity.1Modal content

1. greater than 120.. bcoz strip footing bearing capacity is given by qu = CNc + ¥DNq +0.5 ¥BN, whereas for circular footing bearing capacity is qu= 1.3CNc + ¥D Nq1Modal content

2. less than 120 Q = 1.3 C Nc + Y D Nq + S Y B Ny Since bearing capacity depends on shape factor shape factor (S) of circle is less than square9Modal content
