Reinforced Concrete Mat Foundation Design

It can model analyze and design any combination of two way mat raft slabs individual footings pile caps or grade beams.

Reinforced concrete mat foundation design.

Adapt mat is a versatile three dimensional 3d finite element fem analysis and design software for any configuration of conventionally reinforced or post tensioned foundation system. A guide for practicing engineers published august 15 2012 author s ron klemencic ian mcfarlane neil hawkins. Seismic design of reinforced concrete mat foundations has advanced significantly in the last twenty years. Basic design criteria concentrically loaded d 2 all sides c critical section for two way shear b critical section for one way shear a critical section for flexure outside face of concrete column or.

Spmats program uses the finite element method for the structural modeling and analysis of reinforced concrete slab systems or mat foundations subject to static loading conditions. Where the differential settlement between columns will be small design the mat as reinforced concrete flat slab assuming planar soil pressure distribution. The difference between strong connection and ductile connection precast design is defined. Seismic design philosophy for ductile precast concrete frames is discussed.

7 seismic design of reinforced concrete mat foundations. As analytical capabilities have improved primarily in the form of finite element analysis the mathematical modeling of these continuous structural elements has led to seemingly more precise designs. Nehrp seismic design technical brief no. After the pcc reinforcement steel bars are tied cage in place and then the desired thickness of the concrete according to the design is poured.

Why mat is used. A discussion is presented. 4 3 approximate plate analysis. It is used to support storage tanks industrial equipment silos chimneys and various tower structures.

A mat foundation is a thick reinforced concrete slab supporting arrangements of columns or walls in a row or rows and transmitting the loads to the soil. The method is generally applicable where columns are more or less equally spaced.
