Application of fiber wall element model in nonlinear analysis of steel high performance concrete shear walls
High performance concrete has the advantages of high strength, better fluidity, high durability and impermeability which meet the need of modern engineering structure for large span, high rise, heave load and bad environmental condition. High performance concrete leads an important developing trend in concrete technology (Zhaoyuan 1997; Lü 2004). Because of fragility of high performance concrete and poor deformability of shear wall, its seismic performance, especially deformability, needs to be improved. Steel high performance concrete shear walls was a combination of steel and high performance concrete (SHPC). They can give full play to the advantages of steel and high performance concrete and have better dynamic behaviour, such as ductility and ability of dissipating energy.
