Abstract

Based on nine experiments on edge joints of steel fiber concrete frame, the failure process and characteristics of the joints are studied, and the mechanism model of double shear-compression zone at joint core for shear capacity calculation is presented. The problem that the stirrups and steel fibers work together at the joints is also discussed.Considering the shear stirrups in SFC frame joints, the portion of shear carried by steel fibers should be reduced. As a result, the shear strength formula for these joints is presented, whose results agree well with the test results.
