Abstract
A linked mathematical-informational model to approximate the Force-Drift relationship of surrounding perforated steel plate shear walls under monotonic and cyclic loading is proposed. The proposed model has three physical parameters, along with two curve-fitted factors. These physical parameters are generated from dimensional details and material properties of the shear wall. In this study, two different methods are suggested to consider the intricate hysteretic behavior of perforated shear walls. To use the benefits of both mathematical and informational presentations, a novel method, a linked modeling skeleton, is created and demonstrated through representing the complex hysteretic behavior of perforated shear walls. Hysteretic models are mathematical models capable of simulating the complex nonlinear behavior characterizing mechanical systems and materials used in different fields of civil structures. The model yields acceptable results in good agreement with actual shear wall behavior. Besides, comparison between the presented model and other existing equations, in prediction of the perforated shear wall’s F–D curve, shows the reasonably accurate results of the proposed model.
