Abstract
Numerical experiments of a of the spatial structure joint are presented. Studied the spatial structure joint created by the authors. The joint of spatial structure is protected by a patent of the Russian Federation. The studies were performed in four software systems: Lira (DNDIASB, Kiev), SCAD (SCAD Group, Kiev), CosmosWorks (Structural Research & Analysis Corp., Los Angeles), ANSYS Design Space (ANSYS, USA). Calculations purpose – evaluate the performance of each settlement complex. The evaluation of each computational complex was carried out according to the model creation time, computation time, FE mesh quality and ease of use of the program complex. The results of the evaluation of the accuracy and time of creation of the FE mesh, the accuracy and time of solving the problem were obtained.
