Rozhko V. Strength of keyed joints of concrete and reinforced concrete elements

The object - keyed joints of concrete and reinforced concrete elements; the purpose - improvement of methods of calculation of the strength of keyed joints of concrete and reinforced concrete elements; the methods - are mechanics of solid body, variable method of theory plasticity of concrete, experimental, mathematical statistics; the novelty - the problem of estimate of ultimate load of keyed joints are solved by means of variable method of theory plasticity of concrete taking account profile of keys and width of keyed joint, demarcation of types of destruction and take into account of determining factors of strength, as a result - the influence of profile of keys and width of joint on strength keyed joint; the results have been inculcated in the exploit of technical conditions of reinforce-concrete of frameworks of civil buildings; the branch of application is construction.
