Abstract: Ground motions and air‐blast overpressures produced by the explosive demolition of about 27 structures were compared to determine the importance of these effects. To provide background for this demolition method, general ...

Abstract: An investigation of high frequency, traveling wave excitation of a two‐dimensional, multiple block, rock slope was conducted with a discrete element model to quantify the effects of variable frequency blasting vibrations. ...

Abstract: Blast response was modeled with a two support, two degree of freedom (TDF) system to investigate the importance of traveling wave excitation. Measured structural response was found to correlate better with either single ...

Abstract: Laboratory tests have been conducted to investigate the potential of millisecond delays in blast‐densification of saturated cohesionless sand. A large liquefaction tank was used to prepare and contain the sand. Commercially ...

Abstract: Three-dimensional finite element analysis is combined with field and laboratory measurement of time domain reflectometry (TDR) cable-grout response to analyze the interaction between the cable, grout, and surrounding soil ...

Abstract: This paper synthesizes seven case histories of micrometer changes in the width of cosmetic cracks in a wide range of wall materials and structure types produced by long term (environmental) and transient (blast vibration) ...

Abstract: Quantitatively directed exploration (QDE) employs a first-order Taylor series expansion to combine sensitivity of a 3D finite-element model (FEM) and uncertainty in geologic data to calculate the variance in project ...

Abstract: This paper describes instrumentation and autonomous, Web-enabled remote monitoring of in-service structures to resolve concerns. Structures were subject to dynamic excitation from blasting, construction equipment, and ...

Abstract: Remote operation of a time domain reflectometry (TDR) system demonstrates the effectiveness of telemetric monitoring for early detection of rock movement. During field testing reported here, TDR data were related to shear ...
