Optimization of Truss Height

The article analyzes the task in truss height and in the optimization of the cross-sections of their elements. Element cross-sections are designed of steel profiles considering requirements for strength, stability and rigidity. A mathematical model is formulated as a nonlinear mathematical programming problem. It is solved as an iterative process, using mathematical software package “MATLAB” routine “ fmincon ”. The ratio of buckling is corrected in the each iteration. Optimization results are compared with those obtained applying software package “ Robot Millennium ”. Article in Lithuanian
