Abstract

Abstract

In order to understand the seismic performance and failure mechanism of the prefabricated eccentrically braced steel frame under earthquake action, a quasi-static test was conducted on a one-storey single-span prefabricated eccentrically braced steel frame. The effect of the connection structure of energy dissipating beam section on the seismic performance of prefabricated eccentrically braced steel frames was studied. The failure characteristics of the steel frame under quasi-static load were observed, and combined the test results to deeply analyze the seismic performance indicators such as hysteresis curve, skeleton curve, stiffness degradation, energy dissipation performance, ductility coefficient of this type of structure. The test results showed that this type of prefabricated eccentrically braced steel frame had good seismic performance, and the connection structure of the energy dissipating beam section had an important influence on the prefabricated eccentrically braced steel frame. When the main frame connection form remained unchanged, the frame energy dissipating beam sections connected by extended end plates, the bearing capacity and energy dissipation capacity of the specimen connected by extended end plate were higher than the specimen connected by flush end plates; the failure of the two frames appearred in the energy dissipating beam section, and there was no obvious deformation on the main frame which could meet the seismic fortification requirements of buildings.
