HYSTERETIC BEHAVIOR OF INVERTED L-SHAPED STEEL BRIDGE PIERS FILLED WITH CONCRETE

Abstract

Hysteretic ultimate behavior of inverted L-shaped steel bridge piers filled with concrete under out-of-plane cyclic loading are studied by experimental tests and numerical analyses. The cross-sections of models are non-stiffened box section and stiffened one. The height of filled concrete are changed as a main parameter. The width-thickness ratio of the component plate is about 0.8, the slenderness ratio is about 3.0, the eccentricity ratio e/h (the ratio of the distance e between vertical load and vertical pier axis to the height of pier h) is 0.4. The results of FEM analysis are compared with the experimental results. The hysteretic behaviors of FEM analysis agree well with those of the experiments.
