Design of Reinforced Concrete Shear Wall of Reactor Building, Experimental Power Reactor

Abstract

Shear wall is a vertical structure in a high-level building that serves to withstand lateral loads such as seismic and wind forces. The addition of building height using portal frame structure to withstand lateral force becomes uneconomical because it causes the dimension of columns and beam structure to be large and the number of reinforcement needed more and more. To improve the stiffness and strength of the portal frame structure against the lateral force it is attempted to use a combination of portal frame structure and shear walls. The rigid relationship between columns, beams and shear walls forms the interaction between the portal frame structure and the shear wall thoroughly on the surface of the building. The objective of the research was to know the relation between the strength of the portal frame structure and the shear wall working together to withstand the loads that work both gravitational load and lateral load using SAP2000 withstand seismic force of up to 0.4 gal.The result shows that shear walls with a thickness of 20 cm is able to increase the rigidity of structure. The walls are consist of one layer reinforcements bar diameter is 13mm with spacing is 250 mm.
