Stress-strain state of damaged reinforced concrete bended elements at operational load level

Abstract Each structure is exposed to different influences during operation. As a result, there are various defects and damages of these elements that affect their safe The article presents the results experimental studies reinforced concrete beams with stretched reinforcement made without initial load application. were accepted one or five Ø5.6 mm holes. In case, damage was until beam destruction (up 8.4 opening) Control samples both series destroyed due crushing compressed zone concrete. Samples damaged loading collapsed rupture reinforcement. same type failure identified for at operational level.
