Nosach A. Crack resistance of inclined section of biaxial bended T-beam.

Object of research - crack resistance of inclined sections of biaxial-bended reinforced concrete beams. Aim of research is determination of cost values of separate factors on intense-deformed condition in cracking force and inclined crack width and development design method for biaxial bended T-beam inclined sections. Methods of research are - electrotensometrical, regression analysis, factor experiment planning. Theoretical results are determination of links between shear length, force flat angle, tension concrete resistance and inclined crack force and inclined crack width. Take to account change of geometrical properties of normal section and concrete properties on crack resistance of inclined section. Practical result is engineering method of calculation of crack resistance of inclined section of biaxial bended T-beam. Researched main links crack force and inclined crack width in biaxial bended T-beam. Engineering methods of calculation of crack resistance of inclined section of biaxial bended T-beam are proposed. Results of research has been used in design of state design laboratory "Poltavadipromyasomolprom". Sphere of use - building industry.
