Forcedhaimonicvibration tests, using an eccentricmass shaker, were conducted on two small but different concrete foundations. One foundation Cholame 1E, located in central California, consisted of a 4in.–10cm thick, 50in. 1.27m square slab with corner piers embedded in moderately stiff alluvial deposits. The other foundation Station 6, a 6in. 15cm thick, 48‐in.‐×45‐in.‐(1.22‐m‐×1.14‐m‐)rectangular slab, rested directly on softer deposits in the Imperial Valley of southern California. Experimental foundationimpedance functions, computed from the vibrationresponse data, were similar to theoretical predictions for Station 6; however, significant differences were observed between the experimental and theoretical impedance functions for Cholame 1E. These differences probably resulted from overestimation of the shearwave velocities of the top layers of soil directly underneath the Cholame IE foundation, and to a lesser extent from the use of a simple embedded disk to model the foundation geometry. |
