SEISMIC ELASTO-PLASTIC INTERACTION BETWEEN STEEL RIGID FRAME AND STEEL WALL

Abstract

To demonstrate the seismic elasto-plastic interaction for small-scale structure which is steel rigid frame with steel wall, an analytical investigation is conducted by using the simple model combined the frame of beam-columns with the wall of multibrace. As a result, it is mainly found that the stress distribution of the frame is not monotonically and uniformly increased, that the strain distribution of the wall is not uniformly but consentratedly increased, and that thicker panel gives higher initial rigidity, superiority of strength, and so on.
