Comparison of Damage Criteria for Structures to Near-Field Blast-Induced Ground Motions



Our research aims to compare the existing damage standard for structures subjected to near-field blast-induced ground motions. Sixty-four different blasting records were collected from the selected quarry during 20 months in Trabzon, Turkey. Blasting characteristics such as peak particle velocities, dominant frequencies, air pressures, maximum accelerations, and maximum displacements were measured during the blasting on hard soil. Longitudinal, transverse and vertical peak particle velocities were evaluated using existing vibration standards or damage criteria such as United States (USBM 8507), Germany (DIN 4150), Sweden (SS 25210), India (IS 6922), England (BS 7385), Australia (CA 23), and Turkey. According to the U.S., English and Turkish vibration standards, the measured blast-induced ground motions did not cause the significant damage on the structures as compared with the other standards. It was observed that U.S., English, and Turkish standards are very suitable to evaluate the structural damage level of structures to near-field blast-induced ground motions. In addition, nonlinear dynamic analyses of reinforced concrete (RC) highway bridge were performed. The analytical model was constituted by ANSYS. From the analysis, displacements are increased along to the middle of the bridge deck. The maximum and minimum principal stresses are obtained at the top of the bridge column and at the middle of the bridge spans.
