This project studies to evaluate the performance of existing reinforced concrete building, which was designed to withstand earthquakes. In this project, using a standard four-storey building of the Department of Education as a model for research. After studying the model to strengthen friendly buildings in the country. The brief Reinforced shear wall The extra bracing And clad polymer fiber. Because all three methods are easy construction. And performing
subsequent analysis reinforced through a computer program that can simulate the behavior of non-linear structure with reinforced concrete was found that the shear wall to put the crutches and covered with fiber-reinforced polymer. Have the ability to get more force. However, in terms of toughness may not add up due to strengthening two ways: First, the structure perfectly elastic behavior. And because the structure was not affected somewhat spindly prospects ruined by a slash. Thus reinforced by a third did not see the result as it could be. For the sake of strengthening the 3 to make it a blanket polymer fiber with minimal costs. And the ability to withstand a slight increase of the shear wall to put a charge in the second rank and the ability to withstand high. Adding bracing to be the most costly. And have the ability to get high from minor to enter shear wall.
