摘要：The paperpresents an optimal design and computational solution of truss structures consideringstress concentrations in welded joints. The calculation approach for precise analysis of welded joints using finite element method is introduced. The standard finite element analysis of the truss structure is followed by a special calculation procedure. The procedure is based on the known method of sections. Each member of the truss structure joined at the point under investigation is sectioned off the entire structure. In the next step, a new detailed finite element model of the welded joint is created. These analysis results allow define the stress concentration factors for technical problems of this type. Finally, a specific optimization procedure for design of structures based on the principles of discrete optimization is shown.
