Abstract: The entire spectrum of incremental collapse behavior, including alternating plasticity, shakedown, and plastic (limit state) collapse, of multibay, multistory structures composed of elastic‐perfectly plastic materials can ...

Abstract: Energy methods previously developed for the shakedown analyses of framed structures are extended to include structures subjected to cyclically varying loads in the presence of constant, or bias, loads. This approach is ...

Abstract: The entire spectrum of incremental collapse behavior of elastic‐perfectly plastic multistory rigid‐frame structures can be described by energy methods. The separation between safe and unsafe load ranges coincides precisely ...
