    On the calculation forces from the regulation forces in the structure with variable design scheme
    (Видавництво Львівської політехніки, 2013) Baluk, Igor
    The expressions to determine forces from the regulation forces in the "redundant" linkage of the design scheme that meets the steel structure at some reconstruction stage is presents. These forces are defined by linear combination of unit basic forces that obtained from solving a matrix system of equations finite element method with multiple right parts for the basic design scheme. Factors of the linear combination of unit basic forces proposed to determine by system of linear equations that taking account peculiarities of forces.
