Lateral load resisting systems in high-rise reinforced concrete buildings

The high-rise building becomes very important in construction because every day the prices of land are increasing and the demand is also increased. The more concern matter in high-rise building is lateral loads due to earthquake loads and wind loads. In this study, the classification of lateral load resisting systems has been discussed in chapter 2 for steel structures and reinforced concrete structures. The researcher focused on the reinforced concrete structures (moment resisting system, shear wall system, shear frame system, frame tube system). In chapters 3 and 4, the effects of lateral load (earthquake and wind) were taken in the behavior of building. In the present study, the high-rise reinforced concrete building was analyzed which consisted of 28 floors and it was symmetrical from story 1 up to story 28. The area of building was 625 (25m ˟ 25m), applied dead load is equal 0.5 ton/ , live load is 0.3 ton/ . The well-known structure program ETABS has been used to analyze the structure. The equivalent static method has been used to calculate the seismic load. Tables and charts of displacements and maximum drifts story were obtained.
