| Abstract |
The earthquake in Kobe, Japan showed that there was a great possibility of having an earthquake even in big city and the damages were concentrated on mid or low story buildings which were not considered to be protected from an earthquake. This paper studied the efficiency of retrofitting of reinforced concrete structure which was not designed to endure an earthquake. This experiment used reinforced concrete structure which restrained side-by-side displacement to test durability against an earthquake. Block-filling method and wire-bracing method were occupied to test the degree of efficiency of the methods in case of an earthquake. This study deals with the structural performance of reinforced concrete frame structures strengthened with light weight materials. The conclusions are as follows. 1. Wire braced specimen had a 35%, the cement brick strengthened specimen had a 147%, steel bracing(X-type) specimen had a 122%, steel bracing(K-type) specimen had a 46% and steel bracing (end hunch type) specimen had a 12% higher maximum internal force increase than the standard specimen. |
