COLUMN WEB COMPRESSION STRENGTH AT END-PLATE CONNECTIONS.

Abstract

The length of the yielded portion of the web generally agreed with the maximum load reached, and the measured yield patterns were in general agreement with those obtained in the finite element analyses. The existence of a triangular stiffener plate between a beam flange and an extended end plate was not found to be effective as a method of increasing the yielded length of column web. Thus, results of this investigation indicate the 6k load level is an acceptable and slightly conservative web strength estimate for beam-to-column, moment, end-plate connections. Particular attention must be paid to the local lateral stability of columns without weak axis framing. It also should be noted that no axial load was applied to the column section during testing.
