Experimental Research of Extend-End-Plate and Slit-T Steel Semi-Rigid Connections of Steel Frame

摘要

This paper gained the relation of all kinds of M-θr curves, seismic behaviors and analyzed all kinds of characteristic of dissipation of energy through pseudo-static experiment of four full-scale specimens under cyclic load of extend-end-plate and slit-T steel of steel frame. Strain situation of emphasis section in beam-to-column connections and deformation situation in node position was recorded in the experiment and analyzed damage character and reason.
