The experimental program was composed of one real scale one bay one story reinforced concrete frame 5000 mm 2550 mm 2 center to center designed according to ec2 and ec8.
Reinforced concrete infill walls.
In the past the behavior of masonry infill on panel structures was of great interest in the seismic design procedures and in the evaluation of existing old buildings.
Introduction type cracking of masonry panels is the characteristics of reinforced concrete framed structures are usually infilled with unreinforced masonry brick infill walls as interior and exterior walls.
These elements include the concrete and reinforcement steel which.
More details about the specimens can refer to the references.
The infill walls composed of solid concrete masonry units cmu and mortar were connected to the surrounding columns by tie bars with spacing of 146 mm.
The resulting system is.
Reinforced concrete is a composite material in which concrete s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.
Therefore the structural frame ensures the bearing function whereas the infill wall serves to separate inner and outer space filling up the boxes of the outer frames.
The reinforcement is usually though not necessarily steel reinforcing bars and is usually embedded passively in the concrete before the concrete sets.
Masonry panels behavior as shear walls in masonry structures or infill walls for reinforced concrete panels.
When properly designed masonry infills provide an additional strong ductile system for resisting lateral loads in plane and out of plane.
The blast retrofit of reinforced concrete columns using steel jackets or frp composites wraps was started after the oklahoma city bombing.
Reinforced concrete columns and walls in existing buildings can be economically retrofitted to resist blast effects.
Keywords reinforced concrete frame brick infill seismic behavior earthquake resistance.
For the walls with opening a lintel was provided at the top of each opening to support the upper cmu.
The infill wall is the supported wall that closes the perimeter of a building constructed with a three dimensional framework structure generally made of steel or reinforced concrete.
However 2d frame is recognize accurate to study the behavior of infill walls in term of progressive collapse.
