The presented paper deals with the stochastic analysis of the ultimate limit states of steel‐concrete building members. The load carrying capacity of steel‐concrete columns, comprising of steel profiles encased in high strength concrete, in compression is analyzed. The first part of the paper lists assumptions for the determination of the theoretical load carrying capacity of the column. Principles of elasticity and plasticity are used to determine stresses in the concrete and steel sections. Statistical characteristics of input material and geometrical imperfections are listed. Results of the theoretical analysis are then compared with results of experimental research. Statistical characteristics of obtained results of the theoretical analysis were verified using statistical characteristics obtained from experimental research. Numerical simulation LHS and Monte Carlo methods, which take into account the influences of variability of input imperfections, were employed. The influence of the utilization of the plastic reserve in the determination of the load carrying capacity of the analysed strut is shown. The influence of the initial geometric imperfections of initial strut curvature on the load carrying capacity is also presented.

Single-layer hyperbolic paraboloidal latticed shell dome is adopted in the gymnasium of China University of Petroleum. And the center part of the dome employs crossed web bars in order to increase stiffness of the structure. The 1:12 scale model has been made according to the construction drawings, and the mechanical properties of the model are studied under self-weight load and design load. The regularity of the members' axial force and joints' displacements are obtained. And the results show that the deflection of dome under design load conforms to the requirement of specifications, which verified the correctness of the structure design. It is found that there is no overall instability and local instability, and the behavior of the structure is almost linear.
