Experimental Investigation on the Seismic Behavior of Precast Concrete Beam-Column Joints with Five-Spiral Stirrups
نویسندگان
چکیده
Precast concrete structure is a low-carbon building system that has been attracting extensive attention in recent decades. Beam–column joints are the weak links precast structures. Past studies showed five-spiral stirrups had excellent confinement effects and potential to enhance seismic performance of This study proposed reinforcement beam–column by using investigated their performance. Considering influences joint failure mode, type, construction method, stirrup low-cycle loading tests were conducted on six full-scale specimens. Various behavior indicators, such as modes, hysteresis curves, skeleton ductility, energy dissipation, obtained. The results indicated deformation capacity with was comparable cast-in-place joints. Under different design criteria, superior Furthermore, experimental capacities joints, stirrups, higher than calculated values according code, demonstrating an adequate safety margin. research contributes development sustainable practices field

Performance of the Modified Precast Beam to Column Connection Placed on a Concrete Corbel
Precast concrete structures in Iran are generally designed as continuous columns with hinged beams, thereby making them simple frames. In this system in site show walls in two directions of buildings guaranteed lateral resisting system. However, in order to obtain a seismic resisting frame, the connection between beam and column should be moment resisting and ductile, allowing the formation of ...

a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...
متن کاملSeismic Upgrade of Beam-Column Joints with FRP Reinforcement
Many opportunities are becoming available for using composite materials to strengthen/upgrade existing reinforced concrete (RC) structures. This paper focuses on a new technique for the seismic upgrade of RC beam-column connections in gravity load-designed (GLD) frames by the application (combined or not) of FRP rods and laminates. The FRP rods provide flexural strengthening, whereas the lay-up...

A large share of reinforced concrete (RC) framed buildings is provided with wide beams being a type of beam allowing greater freedom in the architectural arrangement of interiors, beyond further advantage due to fewer formworks needed during the construction. Nevertheless, little attention has been devoted to the seismic vulnerability of this kind of framed RC buildings as well as to the study ...
