DESIGN AND SEISMIC TESTING OF TWO-STORY, FULL-SCALE AUTOCLAVED AERATED CONCRETE ASSEMBLAGE SPECIMEN

Autoclaved aerated concrete (AAC) or cellular concrete, is an innovative new construction material that is currently fabricated in large panels or modular blocks. This article reports on an AAC assemblage specimen that was constructed and tested as the culmination of a research study of AAC structural systems. The objectives of the two-story assemblage specimen were to verify that a system of squat AAC shearwalls designed to fail in a flexure-dominated mode would indeed fail in flexure; to verify proposed design provisions for AAC shearwalls and floor diaphragms; to verify proposed analytical models for such elements and systems; and to verify proposed seismic design procedures for AAC structural systems. The authors discuss background information, specimen design, testing procedure and instrumentation, global results, and individual observed behavioral modes. The authors conclude that the assemblage test met those objectives. The shearwalls conformed to predictive models, with stable hysteretic loops up to drift ratios exceeding 0.3%, and displacement ductilities ranging from 2.5 to 6. The tests confirm that the design objective of flexure-dominated failures can be achieved even with relatively squat walls.
