Annotation: There are given the results of determining wind loads on tower structures including a package of three ventilation pipes and on the structures in the form of a three-pipe package. There was done an experiment in a wind tunnel of a closed type with the open working section above the three-pipe package model. An influence of a wind flow on the thee-pipe package was studied with the help of the FEM. There are presented the pictures of flow past a three-pipe package surface at different angles of a wind flow attack. The shape factor was calculated for a thee-pipe package, a rigging influence and different distances between pipes being included. A qualitative analysis of the stress-deformed state of stack elements was performed. An engineering procedure of specifying a wind load on a trihedral tower structure carrying a tree-pipe package is put forward.
Keywords: pipe package, shape factor, stack.
