Experimental results in behavior of three portal-type structural steel rigid frames; one such frame was subjected to proportional loading, another, to repeated lateral loading causing alternating plasticity in one of members, and third to repeated lateral loading causing incremental collapse of frame; normally employed procedures for determining critical loads, based on simple plastic theory, were found conservative.
