Abstract

The vertical deformation behavior of the 3.5-ft thick mat supporting an 11-story addition to the Wilford Hall Hospital complex near San Antonio, Texas was investigated to determine the mode of deformation and to develop a procedure for estimating the effective stiffness of the foundation soil. The observed distortion pattern is dish-shaped and consistent with that of a plate on a semi-infinite elastic foundation. Measured displacements are consistent with displacements calculated by a plate on elastic foundation finite element program using effective elastic soil moduli between 2,943 and 4,000 kips /square foot and poisson's ratio 0.3. An equation was derived for estimating effective elastic soil moduli for soil with elastic modulus increasing linearly with depth.

Deformation Behavior of Wilford Hall Hospital Mat

The vertical deformation behavior of the 3.5-ft thick mat supporting an 11-story addition to the Wilford Hall Hospital complex near San Antonio, Texas was investigated to determine the mode of deformation and to develop a procedure for estimating the effective stiffness of the foundation soil. The observed distortion pattern is dish-shaped and consistent with that of a plate on a semi-infinite elastic foundation. Measured displacements are consistent with displacements calculated by a plate on elastic foundation finite element program using effective elastic soil moduli between 2,943 and 4,000 kips /square foot and poisson's ratio 0.3.
