The aseismic reinforcement of engineering structures is a kind of engineering technology which is widely used. In the paper,the method of reinforcing aseismic structures by ER intelligent structural elements is presented. On the basis of introducing the working principle of the intelligent structure system, the mechanics model and the experiment results on the ER intelligent structural elements with adjustable parameter used in auto reinforcement are discussed, and its practical application in engineering structures is analyzed. The study results indicate that reinforcing aseismic structures by ER intelligent structural elements is a kind of effective method, and the aseismic ability of ER intelligent aseismic structure system of auto reinforcement is much better than both the old structure and the aseismic structure reinforced by passive control method.
