| Research Abstract |
Enhancement of earthquake resistance of reinforced concrete structures is urgent. It is essential to investigate and predict elasto-plastic behavior of reinforced concrete structures as well as to develop seismic proof systems for this purpose.
The results obtained from this research are follows :
(1) Online Hybrid tests were performed using reinforced concrete column specimens with different shear span depth ratio, reinforcement ratio and compressive stress ratio. As a result, the concept of seismic design in JSCE's concrete standard specification was ascertained to be adequate.
(2) A method of analytical prediction of the earthquake response of a reinforced concrete column was established by only utilizing material characteristics. This result coincided well to the online hybrid test result.
(3) A visual seismic response simulating system was successfully developed using video recorder in pseudo dynamic experiment.
(4) Small size shake table and small size pseudo dynamic test apparatus were successfully developed. Small reinforced mortar specimens were tested by both apparatuses and compared with computer analysis.
