Seismic Performance of Steel-Confined High-Performance Concrete Shear Wall

Seismic Performance of Steel-Confined High-Performance Concrete Shear Wall

Abstract

Natural disasters, such as earthquakes, often lead to the destruction or even collapse of buildings. The selection of a suitable earthquake-resistant structure is crucial and may include steel structures, reinforced concrete structures, high-performance concrete structures and other composite structures with high strength and toughness, etc. Using the advantages of steel construction and high-performance concrete wall panel construction to form a combined system of earthquake-resistant steel frame structures and finished concrete wall panels can effectively improve the seismic characteristics of the structure. This article proposes a study of a steel frame structure bounded by concrete wall panels, and its seismic characteristics as well as a creation of an improved models of finite element analysis of eight structures under horizontal low cyclic reciprocating loads. And the findings are summarised as follow: The calculation of eight walls is compared with each other, taking into account the influence of the geometry of the structure, material, contact nonlinearity, etc. Based on the proven finite element model, the influence of concrete aggregates on the seismic characteristics of the entire structure. Results show that, although highly efficient concrete-filled wall panels reduce the plasticity of the structure to a certain extent, they can effectively increase the load-bearing capacity and overall energy consumption of the entire structure In the absence of a steel frame, the maximum bearing capacity of the four wall panels is comparable, and the properties of CC and RAC have minimal impact on the ultimate bearing capacity and plasticity of the panels. In the presence of a steel frame, the sample with UHPC as the frame of the wall panel exhibits significantly increased bearing capacity and enhanced energy dissipation capacity.
