Shaking Table for the Analysis of Pillars with Top Mass

摘要: In this paper, we present a shaking table designed by the authors, used in laboratory experiments to simulate earthquakes. This equipment makes possible studying dynamic behavior of civil engineering structures subjected seismic motion. Among these structures, bridges won special attention, because they are easily harmed during addition, have importance assuring facile communication case hazards. The most sensitive bridge element is pillar, which supports important bending moments if horizontal forces act on his top. developed authors analyze dynamical pillars with tip mass that represents superstructure. soil displacement simulated main plate, actuated an electric engine ensures different excitation frequencies. analyzed pillar mounted plate via reinforcement element, order increase its stability. Tests were performed frequencies, find out actuation precision. During tests, accelerations at base and top acquired LabView program National Instruments, results shows can be controlled high accuracy.
