EXPERIMENTAL STUDIES ON THE SHEAR RESISTANCE OF ANCHOR BOLTS IN EXPORSED TYPE OF STEEL COLUMN BASES

Abstract

The authors have already reported the results of the study on the shear/resistance of anchor bolt concerned with diameter of anchor bolt, side cover and edge distance to the concrete footing, when shearing forces act upon embedded anchor bolts. Considering the damage conditions of bolts in past earthquakes, in this paper the authors will analyze the failure characteristics of the anchorage of bolts and evaluate the ultimate strength when the bolt heads are subjected to tensile and shearing forces using the specimens whose distance from center of anchor shank to the edge of concrete footing is comparatively short.
