| Abstract |
This study introduces an embedded steel-plate concrete (ESPC) shear wall in which a steel plate is placed within concrete and connected by
studs to ensure composite action. A nominal flexural-strength equation is derived using the strain-compatibility method. Using previous test
data on embedded steel-plate composite walls, a finite-element model was developed, validated, and then applied to ESPC shear walls for
parametric analyses with concrete thickness, steel-plate thickness, and wall length as variables. The results were compared with the proposed
flexural-strength equation. All analysis models showed crack patterns typical of flexural behavior and maintained strength up to about 4.0
percent drift ratio, confirming flexural-dominated response. The average difference between the FEA results and the proposed equation was
approximately 9 percent. These findings indicate that the proposed flexural-strength equation is suitable for ESPC shear walls, though
full-scale tests are needed to more precisely assess their behavior and further refine the equation. |
