ƒ^ƒCƒgƒ‹i‰pjF EVALUATION OF PULLOUT OF LONGITUDINAL BARS FROM FOOTINGS OF RC PIERS UNDER CYCLIC LOADING WITH LARGE DYNAMIC RANGE
´˜^i‰pjF This paper proposes a method for evaluating the amount of pullout of longitudinal bars from the footings of RC bridge piers and RC columns subject to cyclic loading with a large dynamic range. The evaluation of deformation capacity during earthquakes is based on this pullout of steel bars from the footings. A study is also made on a method of obtaining the pullout of steel bars from the footings of reinforced concrete bridge piers and RC columns where the deformation capacity is a ductility ratio of more than 10, resulting in a method capable of accurate results.
