Experimental Research on Ultimate Bending Capacity of Reinforced Concrete Poles in Service Period
In order to evaluate safety performance of reinforced concrete poles accurately, 6 reinforced concrete pole specimens were selected randomly for the bending test. The mechanical behavior and failure mechanism of all specimens were studied, failure modes were revealed, and important experiment data were also obtained, such as cracking loading, ultimate loading, crack development shape, crack width and so on. Based on the experiment data, moment-crack width relationship curve and moment-deflection relationship curve were obtained. Research results showed that failure modes of specimens were similar to “less-reinforced beams”, based on limit state design method in normal use, security surplus factor is 1.27 before collapse damage.
