Abstract
In this paper,it pointed out that enhanced connection and reduced connection are the main measures to achieve ductile steel moment-resisting frame at present.Two kinds of reduced connection,dog-bone connection and connection with opening on beam web are analyzed.Structural forms,mechanical characteristics,reduced parameters and seismic performance of them are described,so as to guide practices.
