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.

提高钢筋混凝土结构的抗震性能是当务之急。本文的主要研究成果如下：（1）采用不同剪跨比、配筋率和压应力比的钢筋混凝土柱试件，进行了在线杂交试验。结果表明，JSCE混凝土标准规范中的抗震设计概念是适当的。(2)建立了一种仅利用材料特性分析钢筋混凝土柱地震反应的方法。该结果与在线混合动力试验结果吻合较好。(3)利用视频记录技术成功地开发了拟动力试验地震反应可视化模拟系统。(4)成功地研制了小型振动台和小型拟动力试验装置。用这两种仪器测试了小型钢筋砂浆试件，并与计算机分析进行了比较。
