survey of influence of opening area to wall area ratio on stiffness and yielding resistance of concrete shear wall system

the presence of openings in the concrete shear wall system reduce the power of the system in loading, so in this study first using a valid experimental specimen validity of results from an ansys software has been done. after ensuring the modeling and obtained results concrete frame with concrete shear wall system return function have been investigated using modeling the structures with different percentage of opening to whole of wall in ansys software and doing the non-linear static analysis (hysteresis) according to atc 24 results from hysteresis analysis of models show the system power reduction and they're complicity of the system collapse in energy dissipation in cycling loading.
