DETERIORATING PROCESS OF REPAIRED/STRENGTHENED REINFORCED CONCRETE MEMBERS MEASURED BY HYBRID LOADING SYSTEM OF EARTHQUAKE RESPONSE
|
´˜^i‰pjF
The seismic behavior of repaired/strengthened RC structures is difficult to analyze theoretically. However, this paper will show that analysis can be effectively done by using the so-called HYLSER (Hybrid Loading System of Earthquake Response) system. Three repairing/strengthening methods were considered: (1) the epoxy resin grouting method; (2) the reinforcing bars welding method; and (3) the steel plate covering method. Obtained stiffness deteriorating processes were verified to be almost the same as those of the original ones if adequate repairing methods were performed.
