Transcript of Mat Footing (Design)


Conventional Rigid Methods / Approximate Method
-Conventional Method of Static Equilibrium

Approximate Flexible Method
-This method was suggested by ACI Committee 336 (1988), design is aided by AIRPAVE computer program. STRUCTURAL DESIGN OF MAT FOUNDATIONS •Rigid Methods Winkler Method (bed of springs)

Coupled Method (dish shape)

Pseudo-Coupled Method
-Uses different ks (modulus of subgrade reaction) values depending on the location of the mat.

Multi-Parameter Method •Non-rigid Methods Finite-difference method

Finite-element method

Finite-grid method •Finite Element Methods The plan of a mat foundation with column loads as shown, calculate the soil pressure at points A, B, C, D, E, and F. The size of the mat is 16.5m x 21.5m. All columns are 0.5m x 0.5m in section. Given qall(net) = 60KN/m². Determine the reinforcement requirements in the y direction. Given fc’ = 20.7 MPa and fy = 413.7 MPa. Use a load factor of 1.7. Sample problem using conventional rigid method
