| Abstract |
The seismic behavior of the lightly reinforced concrete frames (LRCFs) was controlled by the nonductile behavior of the critical regions. These critical regions require retrofit to improve the seismic behavior of the lightly reinforced concrete frames. Critical column end regions must be retrofit to increase the global ductility capacity. The objective of this research is to evaluate structural strengthening performance of lightly reinforced concrete frame with high performance fiber-reinforced cement composites(HPFRCCs) experimentally. The experimental investigation consisted of a cyclic load tests on 1/3-scale models of one story-one bay lightly reinforced concrete frame infilled wall. Material ductility and web panel reinforcement details were variables in the experiment. The experimental results, as expected, show that the multiple crack pattern, strength, ductility and energy dissipation capacity are superior for specimen with HPFRCC infill wall due to bridging of fibers and stress redistribution in cement matrix. |
