Study on Structural Properties and Damage States for R/C Frame with Walls

Experimental Test on Structural Properties and Damage States for Non-Structural R/C Wall Vertically Located in a Span with Spandrel Walls

Abstract

The examples of damaged R/C building with walls in Tohoku Earthquake were collected. And, the standard prototype data of the frame with walls was proposed. In order to understand structural properties and damage states for non-structural R/C wall vertically located in a span with spandrel walls, the structural experimental test of three specimens, which variable parameters are different opening patterns, wall thicknesses and wall bar arrangements was conducted. The experimental result showed that the structural characteristics were highly-influenced by the presence of the spandrel wall, and allowable strength evaluated by the AIJ standard of R/C was on the safe side, and that initial stiffness was calculated rather highly, ultimate strength was calculated precisely in the skeleton curve.
