Axial Force-Moment Interaction Diagrams to Calculate Shear Wall Reinforcement

One of the most important resistant systems which are used in concrete structures is moment resisting frames. One of the defects of this type of resistant system is the great lateral drift, therefore concrete or steel shear walls are used to reduce lateral drift. Using resistance frame and shear wall together in a structure is known as dual system. Shear walls resist lateral forces due to earthquake or wind; therefore, calculation of shear walls dimension and reinforcement with few mistakes possible and in a correct way is very important.In this study, drawing axial force-moment interaction diagrams to calculate shear wall reinforcement will be discussed. Uniform reinforcing approach based on ACI 318-83 code was used to obtain equations which were independent of shear wall dimensions. Axial load-moment interaction diagrams are presented as results which can be used to calculate shear wall reinforcement. Mistake elimination and calculation speed increased are the most important benefits of these diagrams which are used to calculate shear wall reinforcement.
