Effect of Vibration on Concrete Strength During Foundation Construction
Many studies have been conducted on the effect of construction vibrations on properties of freshly placed concrete. This study was concerned with the drilled shaft construction and its effect on the green concrete. The differences between the common construction vibrations and those produced during drilled shaft construction are the amplitudes and duration of vibrations. To characterize the type of vibrations induced during drilled shaft conctruction, a full scale field testing was conducted using a typical steel casting. The peak particle velocities (ppv) were recorded and empirical relationships were suggested to predict the velocity values on the surface and in the ground along the penetration depth of shaft. Laboratory testing was conducted to determine the effect of ppv and different durations of vibration on green concrete properties. The duration of vibration is used in this study, including the initial and final time settings.
