Hybrid fiber reinforced concrete special shear wall boundary element in compression

چکیده
Post-earthquake observations and laboratory tests reveal the needs for innovative solutions that can enhance concrete compression ductility in boundary elements of special structural walls. This study proposes a new element design by utilizing hybrid fiber reinforced (HyFRC). One full-scale HyFRC is tested uniaxial compared to three conventional are compliant with ACI-318 codes. Results demonstrate replacing (1) control early-stage surface damage, (2) improve confinement core, (3) delay onset longitudinal bar buckling. Relative elements, which lose load capacity after spalling, exhibits unique post-spalling plateau improves toughness more than 150%.

nonlinear fiber element analysis of a reinforced concrete shear wall subjected to earthquake records
verifying the behavior of shear walls in a tall building requires reliable response results. this paper examined nonlinear fiber element modeling of a slender reinforced concrete shear wall during large-scale shaking table testing. the goal was to understand and validate the inelastic responses given by fiber models using time history analysis. reasonable agreement was found between the numeric...
متن کاملHysteretic Behavior of Conventionally Reinforced Concrete Coupling Beams in Reinforced Concrete Coupled Shear Wall
This paper presents the experimental results of four full-scale coupling beams in which only horizontal reinforcements are placed, without diagonal reinforcements, with the aim to develop reinforcement details for coupling beams used in connecting side walls in a wall-slab structural system. Each coupling beam specimen was designed according to the deep-beam design procedure that does not use d...
متن کاملHybrid Fiber Reinforced Concrete Containing Pumice and Metakaolin
Fiber reinforced concrete (FRC) has been widely used due to its advantages over plain concrete such as high energy absorption, post cracking behaviour, flexural and impact strength and arresting shrinkage cracks. But there is a weak zone between fibers and paste in fiber reinforced concretes and this weak zone is full of porosity, especially in hybrid fiber reinforced concretes. So it is necess...
متن کاملSeismic Performance of Steel Plate-Reinforced Concrete Composite Shear Wall
In tall buildings the reinforced concrete (RC) shear wall is one of the predominant structural components used to resist lateral loads induced by earthquakes around the world. Previous research demonstrated that shear walls displayed a sudden loss in lateral capacity due to the wall corner and web crushing in the plastic zone. In addition, it was found that large shear distortions in shear wall...
متن کاملConcrete Shear Wall Construction
Buildings with cast-in-situ reinforced concrete shear walls are widespread in many earthquake-prone countries and regions, such as Canada, Chile, Romania, Turkey, Colombia, the republics of the former Soviet Union, etc. This type of construction has been practiced since the 960s in urban regions for mediumto high-rise buildings (4 to 35 stories high). Shear wall buildings are usually regular in...
