17 Rigid and flexible mat foundation Efficiency Practically performance Cost-effective Rigidity Flexibility Mechanical properties of concrete and subgrade Geometry of the foundation Geometry and reaction of the soil layers Dissipation of seismic loading
18 Rigid and flexible mat foundation Efficiency The bending moments subject to the raft foundation are the critical factors for designing the raft foundation. The shear wall reduces the nonlinear settlement of the foundation. The pile under the foundation is reducing the settlement of the foundation. The raft foundation changes the applying load and reduces the liquefaction possibility
