Article Preview

Based on the low cyclic loading experiments on three interior joints with specially shaped columns, in which one of them was reinforced by polypropylene fiber in the core zone of joint, another steel fiber, the other was not reinforced, the authors compare the results in terms of damage characteristic, bearing capacity, displacement and ductility, hysteretic curve of the moment-rotation, rigidity degradation and energy dissipation. It is shown that seismic behavior of specially shaped column interior joints reinforced by fiber is improved significantly. The interior joint of specially shaped column reinforced by polypropylene fiber has a better damage characteristic and energy dissipation while that by steel fiber shows a higher yield load and bearing capacity.
