Vibration Testing of Cantilevered Steel Pole with Partial Concrete Filling
Wind-induced fatigue failure of traffic and light poles has not been sufficiently studied neither has it been used as a design criteria by many pole manufactures. This paper presents the results of experimental testing of a new steel-concrete composite pole. The new pole features a thin-walled hollow steel tube partially filled with concrete near the base. The experimental work aimed to evaluate the natural frequencies of the poles and find the optimal concrete filling length for the best dynamic performance. Experimental results showed that for the tested poles, the optimal length of concrete filling ranged between 37% and 43% of the total length, and yielded 18% to 26% increase in the first natural frequency of the pole. The experimental results were within 10% difference when compared to predicted values using a finite element-based modal analysis. The new optimized composite poles, with natural frequencies higher than the inherited frequencies of typical wind loads, would better endure wind-induced vibrations.
