Abstract

Purpose. The paper is devoted to experimental study data of autoclaved aerated concrete stress-strain diagrams after high heating and fire resistance evaluation.

Methods. The specimens of autoclaved aerated concrete were heated in muffle furnace and tested at breaking machine. The results were analytically discussed and fire resistance evaluation technique pro-posed.

Findings. The autoclaved aerated concrete stress-strain diagrams after heating are found. Shrinkage rate depending on temperature is determined. The fire resistance evaluation technique is proposed. Research application field. The obtained experimental study data could be used in fire resistance design of autoclaved aerated concrete structures.

Conclusions. Fire resistance design of autoclaved aerated concrete structures should include stress-strain diagrams after heating study jointed with shrinkage rate.
