抄録

The objective of this paper is to demonstrate the aseismic capacity of concrete-filled tubular members subjected to cyclic axial load. About fifty specimens composed of cold-formed circular tubes and normal concrete were tested to quantify the number of loading cycles and the amount of dissipated energy upto breaking failure after local buckling. The test shows that both the failure cycle and the dissipated energy are fairly increased by filling the tube with concrete. The span of life of concrete-filled tubular member is affected by the diameter-thickness ratio, effective length and amplitude of axial displacement, and is successfully predicted by an estimation method proposed by authors. The dissipated energy upto failure can be also predicted by means of multiplying the number of loading cycles upto failure and the dissipated energy at each loading cycle. The dissipated energy and deformation capacity of concrete-filled tubular member with alternative diameter-thickness ratio and effective length are discussed from the results of test and theoretical estimation.
