September 18-20, 1991 InternationAl Conference Manchester, on Earthquake, Blast and Impact U.K. Organized by the Society for Earthquake and Civil Engineering DynAmlcs, this conference will bring together clients, consultants, contractors, manufacturers, academics and researchers to discuss the state of the art and future developments in this field. Particular emphasis will be given to the measurement and testing of the dynamic behavior of structures and structural elements, and their effects on plant and people. The main emphasis will be on: Sources and measurement (earthquake, blast, shock, impact); Response and measurement (displacement and stresses);Industrialcase histories (plant/equipment/structures); Testing equipment (on site/inlaboratory); Construction effects(pilingand demolition);Analysis and design aspects; Code issues;and Mitigation ofeffects.For more information contact:The Conference Office,Institutionof CivilEngineers, 1-7 Great George St., London S W I P 3AA, U.I~ September 24-26, 1 9 9 1 Hradec, Czechoslovakia
