Cyclic loading of Shear-bending yielding damper in Abaqus

Product Overview

In this project, we simulate a shear-bending yielding coupling (SBYC) damper under cyclic loading in Abaqus.

The damper consists of a shear plate, bending plates, and end plates. The bending plates are arranged on both sides of the shear plate, providing out-of-plane restraint to limit the buckling of the shear plate while also contributing to the lateral resistance of the damper.

The Abaqus model is used to investigate the cyclic behavior, force–displacement hysteresis response, shear plate buckling, and damage behavior of the damper. The numerical results are compared with the experimental results reported in the reference study.

Cyclic Loading

The SBYC damper is subjected to displacement-controlled cyclic loading to investigate its hysteretic behavior under repeated loading and unloading cycles.

The cyclic loading protocol used in the experimental study is reproduced in the Abaqus model. The applied displacement produces shear and bending deformation in the damper, allowing the numerical model to capture the hysteretic response, shear plate buckling, and post-buckling behavior.

Force–Displacement Hysteresis Diagram

The force–displacement hysteresis diagram is obtained from the Abaqus analysis to evaluate the cyclic response of the SBYC damper.

The numerical hysteresis response is compared with the experimental results to examine the ability of the Abaqus model to reproduce the strength, stiffness, and overall cyclic behavior of the damper.

Buckling of the Shear Plate

The buckling behavior of the shear plate is investigated in the Abaqus model under cyclic loading. The bending plates on both sides of the shear plate provide out-of-plane restraint, which helps limit the buckling deformation of the shear plate.

The numerical results are compared with the experimental specimen to evaluate the ability of the Abaqus model to reproduce the observed buckling behavior of the shear plate.

Damage in the Shear Plate

The damage behavior of the shear plate is investigated in the Abaqus model under cyclic loading. The repeated loading causes significant deformation in the shear plate, leading to the development of damage as the loading progresses.

The numerical results are compared with the experimental specimen to evaluate how well the Abaqus model reproduces the observed damage behavior of the shear plate.

Validation

This project has been validated, which means that the results obtained from the Abaqus software are similar to the results reported in the article.

In other words, this project is based on the reference article and the numerical model has been developed to reproduce the behavior of the experimental yielding damper.

Energy Dissipation

The SBYC damper dissipates seismic energy through the inelastic deformation of the shear and bending plates. Under cyclic loading, both components contribute to the hysteretic response of the damper.

The Abaqus model is used to investigate the deformation and yielding behavior of the shear and bending plates and their contribution to the overall cyclic response of the damper.
