摘要:
The structural system of the resilient prestressed steel frame with intermediate column containing friction damper and the typical details of the intermediate column containing friction dissipation damper were put forward for researching the resilient capacity to large-span prestressed steel structures. An eight-story prototype structure was designed and a static pushover test of the first two-story plane frame was conducted. The numerical simulation was also carried out by using the software ABAQUS. The results show that, the intermediate column containing friction dampers increases not only the structural rigidity but also the energy dissipation capacity. The main structure still remains elastic except the reinforcing plate of beam flange and web plate of column foot. The story shear force-displacement hysteresis model of the two-story plane steel frame was acquired by the pushover test, and the hysteresis models of story 1 and story 2 exhibited shuttle shape and arc shape respectively, which is the basis of further study on the mechanical performance of the structural system. The loss of prestressing steel strand force is very little after the test and can provide an excellent self-centering mechanism and capacity of resilient structure function. © 2016, Science Press.
