The seismic performance of recycled aggregate concrete (RAC) composite shear walls with different expandable polystyrene (EPS) configurations was investigated. Six concrete shear walls were designed and tested under cyclic loading to evaluate the effect of fine RAC in designing earthquake-resistant structures. Three of the six specimens were used to construct mid-rise walls with a shear-span ra...

This paper reports the findings of research examining the blast resistance of bridge piers that are designed in accordance with current knowledge and specifications to ensure ductile seismic performance. Blast testing was conducted on 1/4 scale ductile RC columns, and nonductile RC columns retrofitted with steel jacketing. The seismically designed RC and steel jacketed RC columns did not exhibi...

Steel plates in double skin composite (DSC) panels are restrained by a concrete core and welded stud shear connectors at discrete positions. Local buckling of steel plates in DSC panels may occur in a unilateral mode between stud shear connectors when subjected to combined states of stresses. This paper studies the local and post-local buckling strength of steel plates in DSC panels under biaxi...

Multi-partition steel tube formed T-shaped composite shear wall is a new type of which enhances the structural performance compared to traditional wall. To clearly understand behavior such walls, eight half-scaled specimens were tested study their axial and seismic behavior. The failure mechanism, energy dissipation ability observed according experiments. experiments showed that strength cross-...

In this paper, a new approach for nonlinear numerical modelling of the reinforced concrete shear walls with consideration of bar-concrete interaction and shear deformation is proposed. Bar and concrete stress-strain relations, the bar-concrete interaction, the shear stress-strain relation and, also, their cyclic behavior including the strength degradation and stiffness degradation are adopted a...

Shear wall is one of the common lateral bracing systems in reinforced concrete structures. A coupling beam can be used due to architectural limitations for connecting two or multiple separate walls. Coupling beams are most vulnerable elements coupled shear systems. Therefore, could designed act as replaceable fuses system. This paper investigates application viscoelastic dampers (VCD) and steel...
