| Popis: | Evaluation of hysteresis behavior and ultimate capacity of steel plate shear walls (SPSWs) with complex geometry and details, using the equivalent constitutive models infill steel plate, is known as a complex process. Therefore, using a simplified micro-finite element (MFE) model is necessary in evaluation of the hysteresis behavior and performance of the SPSW with different construction details. The proposed MFE model was performed in microscopic analysis models for web-plates and boundary members. To this end, comprehensive verification studies are initially performed by assessment of between the MFE model predictions with several reported test results in order to demonstrate the reliability and accuracy of the implicit analysis method. Comparison is made between the hysteresis curves, failure modes, and base shear capacities predicted numerically using ABAQUS software and obtained/observed experimentally. The results of this analysis exhibit that the proposed MFE model can evaluate the hysteresis behaviour and failure mode of SPSW structures with any type of geometric and materials properties. Meanwhile, this proposed model was implemented so that designers are capable to comfortably using the proposed model with good computational accuracy and efficiency. |
