The aim of this topic is to describe creating of working diagrams of structural materials. These will be used as input parameters for nonlinear analysis of real structures. Working diagrams of construction material are derived from experimental tensile tests and numerical analysis. We will use construction steel in this case. Derived working diagrams are used as an input parameter for numerical modelling of real structures. They are also used as a comparison with data from realized physical tests. Numerical modelling is based on 3D model of structure and it takes into account physical and geometrical nonlinearities. K EYWORDS .

I NTRODUCTION esign of steel structures is done according to standard EC and recommendations [1]. These methods are accurate for global analysis of construction and also for design of its structural parts. Nowadays advanced methods for assessment of civil constructions are using. These methods with usage of experimental measuring are based on sophisticated numerical analysis. This article describes process of creating working diagrams of steel in detail [2]. Afterwards input data are used for analysis of construction of suspended ceiling [3]. Currently method of finite elements is mostly used for numerical analysis of civil structures [4] and mainly for steel constructions [5, 6]. Finite element methods can appropriately take into account different nonlinearities [7, 8]. One of new methods used for solution of resistance of steel connections is for example CBFEM [9]. This method extends component method and uses FE method. These methods are easily implemented to calculation software for civil engineering. There D
