Comparative Study on the Behaviour of Composite Steel-Concrete Shear Walls Under Lateral Loads
The research focused on the solutions to create performant elements for seismic resisting structures has increased in the last decade. Different hybrid solutions that have composite steel-concrete structural shear walls with steel encased profiles (CSRCW) were studied. The benefits of this structural system include high performance characteristics in terms of ultimate loads, deformations capacity and ductility. The paper presents a comparative study on the behaviour of CSRCW, both solid and with centred openings. The study is based on the theoretical and experimental results obtained on steel-concrete composite elements 1:3 scale, tested in laboratory under cyclic lateral loads. All specimens were tested under constant vertical load and cyclically increasing horizontal (lateral) loads. The tests were performed until failure. The comparative study is focused on the main parameters: maximum load bearing capacity, stress and strain distribution in structural components, cracking patterns, deformation and degradation capacity. The conclusions indicate that the composite solution of steel concrete shear walls, lately addressed also as “hybrid”, with or without openings, could offer enhanced load bearing capacity, energy absorption and relatively gradual stiffness degradation.
