ABSTRACT

The double-skin truss-reinforced composite shear wall is a type of composite wall with steel plates connected by truss connectors. Established studies have demonstrated the improvement of compressive and shear performance of double steel plate composite shear walls by truss connectors. The structural design of truss connectors is discussed in detail in this article. The upper limit of the connector spacing-to-thickness ratio is investigated based on the elastic stability theory and the superposition principle, and a limit value of 65k is recommended. Based on the plastic hinge theory, the existing test results and the relevant standards, the design recommendations of truss steel bar diameter and bending angle are provided. Other strengthening construction measures are also given to minimize wall damage.
