Analysis Of Pseudo-static Experiment Of Pre-stressed Fabricated Concrete Frame

Pre-stressing concrete fabricated structure is formed by applying concretecomponents with pre-stressing force. it has the advantages of the prefabricatedstructure because of the prefabricated components. As the role of the pre-stressingforce which between the components has greatly improved the integrity offabricated structures, the structure overcome the poor reliability of the fabricatedstructure connected nodes，this kind of frame systems possess higher reliability andsolved the problems in the precess of assembling Concrete frames.Based on the pseudo-static and pseudo-dynamic test of a specimen of two floordouble-span pre-stressed fabricated concrete frame, this paper first describes thetest equipment,loading method,the measuring points and experimental phenomenaand etc.Then,the article researches the seismic performance such as the beam endnode process and the mechanism of force, hysteretic behavior, skeletoncurve,ductility,energy dissipation capacity,deformation recovery capability andetc,and concluses that the prestressed connections drawn in the assembly structureof the node on the overall structure of the earthquake is favorable. The same time,using ANSYS software, the use of nonlinear finite element analysis methodapproximation to simulate the force of the framework. Found by comparison withthe experimental framework, the overall measured data and the simulationstructure is relatively little difference, but there is still a gap between theindividual analysis with the measured values, the gap is caused by a variety ofreasons. Studies show that pre-stressed fabricated concrete frame has better seismicperformance.
