Cathy Aimone-Martin, Brent Meins, James Lauer, and Robert Brenta share their views on the response of tall structures to close-in urban blasting in New York City. They summarize four years of measurements of tall structure motions to high-frequency close-in urban blasting in New York. They reveal that 22 tall structures have been instrumented with velocity sensors to compute global wall strains till May 2014. The goal of this effort is to assist the Fire Department of New York (FDNY) to develop a strain-based damage criterion for mid- and high-rise urban structures and a modified frequency-based peak particle velocity criteria similar to the safe blasting curve developed by the US Bureau of Mines for 1- and 2-story residential structures. It is envisioned that the development of a close-in urban blasting criteria for tall structures that considers historic and landmark buildings may serve as a model for other urban environments.
