Mathematical modelling deflected mode of flexible shells anchored along the contour
Thin walled cold-formed steel structures became popular solution for low-rise buildings, mansards, walling of multistorey buildings. The modeling of perforated thin-walled cold-formed profile is rather difficult, especially for profiles with irregular shape apertures used in racking systems.
The main aim of this work is creating the methods of finite element modeling such profiles.
The result of work is a method of construction of profile with given section, aperture formation and construction of final calculation model. The software package SCAD Soft was used for modeling.
