Shaking table test for a scale-down reinforced concrete structure considering corrosive deterioration

Abstract

The degradation of concrete and rebar corrosion are considered a key factor in the durability of reinforced concrete structures and a major concern for civil engineers over the past few years. This study is focus on the variation of natural frequency, dynamic properties and seismic spectral in a deteriorated scale-down reinforced concrete frame specimen with rebar corrosion. The dynamic properties were experimentally studied though shaking table tests and the corrosive behaviors were experimentally studied though accelerated corrosion test. Test results presented that the corroded reinforced concrete specimens presented the changes in the dynamic response especially natural frequencies and response spectrum and rebar corrosion caused significant charges in dynamic responses. In conclusion, the deteriorated scale-down reinforced concrete test is useful for structural assessments and appraisals applied to full-scale structures
