experimental investigation of cyclic behavior of precast exterior beam- column joints
Post: #1

In spite of numerous advantages of Precast concrete construction, its use in high seismic areas is not popular, mostly because of the low level of confidence in its behaviour in these places. The joints between Precast elements are the critical regions in Precast structures from seismic considerations, as validated by their poor performance in many past earthquakes. Experiments are performed on four exterior beam-column joint sub assemblage specimen. Two of these are Precast and the other two correspond to monolithic ones, which serve as a benchmark for comparison. A pair of monolithic and Precast specimens has a different scheme for the anchorage of beam bars. In Precast specimens, the beam and column bars are anchored together through welding the exposed bars of the components. Displacement-controlled pseudo-static loading is applied on the specimens. The Precast specimen with beam bars anchored into the column performed better than the Precast specimen with continuous U-bars as beam reinforcement. The performance of the former was comparable to the corresponding mono

The beam-column joint is an important component of a reinforced concrete (RC) frame that must be properly designed and detailed, especially when the frame is subjected to seismic forces. Many of the existing structures located in the seismic-prone area were designed and built on the foundations of the previous codes with inadequate ductile reinforcement detail. At present, although these structures do not deteriorate, they are structurally inadequate. Therefore, it is necessary to update these structures using more economical and reliable reinforcement techniques. A total of 12 specimens corresponding to four sets of tests were cast and tested under cyclic loading to study the load-strain behavior, parameters associated with ductility, final load capacity and failure characteristics. SIFCON 20 mm thick prefabricated laminates were used to reinforce conventional RC and fiberglass beam and column joints. For laminates, the volumetric fraction of fiber was 9%. The steel fibers used in the study were rounded cylindrical fibers having a diameter of 0.5 mm with the aspect ratio 60.

Prefabricated concrete structures make up a significant proportion of buildings in the world. This clearly makes the construction market competitive, especially with the scarcity and costly jobs in the current construction market in most countries. Prefabricated concrete is defined as concrete that has been prepared for casting, molding and curing in a place that is not its final destination; its elements are reinforced either with steel reinforcing bars or with prestressing wires. A prefabricated concrete structure is a set of prefabricated elements that, when properly connected to each other, form a three-dimensional framework capable of withstanding gravitational and wind loads (or even earthquake). Prefabricated concrete offers opportunities to accelerate on-site construction processes, maximum reuse of work and mold equipment and for process continuity. There is a reduction in the amount of in situ concrete required at the site and a reduction in delays caused by bad weather and seasonal conditions. With the aforementioned advantages, the most economical feature in the prefabricated concrete industry is the standardization of the products; this has a great influence on the profitability of the industry. The success of prefabricated concrete buildings depends on component connections, particularly beam-to-column connections.
