Abstract

Abstract

For the effect of stirrup ratios on damage characteristic, hysteretic characteristic, rigidity degradation, ductility performance, energy dissipation capacity of T-shaped and L-shaped columns, through quasi-static test method, four concrete specially shaped columns, high strength steel bars were tested under low cyclic loading.The component failure characteristics and ductility performance were analyzed, hysteresis curves and stiffness degradation curves and equivalent viscous damping coefficient curves were also plotted.The results show that descending parts of the hysteresis loops of specially shaped columns, high strength steel bars and concrete are steeper and the ductility was also worse.The damage characteristic and the hysteretic characteristic of specimens were improved with the increase of stirrup ratios.The energy dissipation capacity of T-shaped column and L-shaped column were also enhanced with the increase of stirrup ratios.
- specially shaped column,
- high strength steel bars,
- low cyclic loading,
- seismic behavior
