Abstract:

Rectangular bridge columns in high seismic areas require high amounts of confining steel. Self-consolidating concrete is ideal for the construction of concrete members with high steel congestion. However, there is lack of data on the seismic performance of rectangular self-consolidating concrete bridge columns. The study had two main objectives: 1) assess stress-strain relationships of self-consolidating concrete (SCC), and 2) evaluate the seismic performance of rectangular SCC bridge columns. To accomplish the first objective, three SCC and four conventional concrete (CC) mixtures were designed, batched, and tested under uniaxial compression. Fresh and hardened properties were measured, and typical stress-strain parameters were evaluated to compare SCC to CC mixes. To fulfil the second objective, two SCC and two control CC rectangular column specimens were designed, fabricated, instrumented, and tested under combined axial load and quasi-static cyclic lateral loading.
