Abstract

The computation of coupled response of block foundations subjected to a constant magnitude harmonic horizontal force or moment or both, is very important for the design of block foundations. Mathematical relationships for computing response of rigid block foundations using the elastic half-space method lite available but are not in an easily understandable format. More over relationships available for embedded foundation are for the case when both horizontal force and moment are acting on the foundation. To extract the solution for the case when either horizontal force or moment alone is acting from the existing relationships is extremely difficult, if not impossible. A unified general mathematical solution has been developed to compute the response of block foundation resting on the surface of elastic half-space and/or embedded into the elastic half space with a soil side layer, and rigid block resting on piles, subjected to a harmonic exciting function at the top of foundation. Relationships have been put in a format easily understandable by practicing engineers.

Coupled Horizontal and Rocking Vibration of Block Foundations

St. Louis, Missouri

The computation of coupled response of block foundations subjected to a constant magnitude harmonic horizontal force or moment or both, is very important for the design of block foundations. Mathematical relationships for computing response of rigid block foundations using the elastic half-space method lite available but are not in an easily understandable format. More over relationships available for embedded foundation are for the case when both horizontal force and moment are acting on the foundation. To extract the solution for the case when either horizontal force or moment alone is acting from the existing relationships is extremely difficult, if not impossible. A unified general mathematical solution has been developed to compute the response of block foundation resting on the surface of elastic half-space and/or embedded into the elastic half space with a soil side layer, and rigid block resting on piles, subjected to a harmonic exciting function at the top of foundation.
