Hama R. Toughness steel reinforced concrete elements with transverse finely sheet by armature under axial compression

Object - concrete, reinforced concrete, steel reinforced concrete; aim - designed scheme armature and the method of the calculation to toughness compressed steel reinforced concrete with transverse finely sheet; the methods - experimental, analytical, graphics analytical; novelty - in a part of the experimental studies are received given about toughness: concrete sample of the square section b x b =150 x 150 (mm) and height h=600мм; 150мм, 100мм and 75мм, made from heavy concrete of the class В35 and В50, reinforced concrete; the steel reinforced concrete with longitudinal pivotal and transverse utter finely sheet (the thickness of the sheet t=1,8 mm) by armature (in series "A" and "В"), transverse finely sheet t=1,8 mm with axial hole dвн= 0,4b = 60 mms (the series "Б") and dвн=0,5 b =75 mms (the series "Г"); in theoretical part: is designed a function within the framework of theory of the slide; the results - an average factor of strengthening concrete depending on correlations h(S*)/b=1; 2/3; 0,5 reached following importance's, accordingly: for common concrete of the class В35 - 1,419; 1,94; 2,472; ditto in composition steel reinforced concrete - 1,407; 1,744; 2,166; for plasticizers concrete of the class В50 - 1,29; 1,711; 2,164; ditto in composition steel reinforced concrete - 1,285; 1,614; 1,934; application - a designing compressed element.
