Study on the Effect of theReinforcement Percentage (ρ) and the Dimensions of the Building Span on the Behavior of Concrete Structures with OpenShear Walls Against Progressive Failure under FEM Finite Element Analysis

One of the challenges that threaten buildings today is the discussion of the progressive devastation caused by earthquakes and fires. In most seismic and explosive events, most of the casualties have been caused by the demolition of buildings compared to any other direct impact; therefore, ensuring the sustainability and non-demolition of buildings is of primary importance. However, even if properly designed ductile buildings are exposed to certain undesirable features, they will suffer extensive damage. Therefore, it is necessary to apply the principles of earthquake and explosion resistant design in three different levels of structural forms, building plans and ductility for all buildings. This can cause problems for structures designed on the basis of current regulations during severe earthquakes and even lead to total demolition. In other words, any weaknesses in the design or implementation of the components may lead to the progressive failure of structures during the loading of an explosion or earthquake. Pop-up shear walls in concrete buildings are designed due to architectural limitations. These walls are less resistant than conventional shear walls, but they increase the structural ductility. Although the design of such walls is based on valid regulations and regulations, it is not considered progressive failure and in cases where the structure does not have the necessary resistance to progressive damage, reinforcement is required. The Progressive Damage Issue in Concrete Shear Wall Structures, which form the basis of the present study, examines the effect of reinforcement percentage (ρ) on the progressive failure. Progressive failure has not been investigated so far, considering the importance of this issue in this study, we investigate the effect of parametric change of reinforcement percentage (ρ) on the behavior of concrete structures under progressive failure. At the end of the study, the results showed that the effect of increasing the percentage of reinforcement (ρ) on reinforced concrete structures under an explosive load and progressive failure would improve the performance of the structures.
