Original Abstract

The proposed contribution describes the formulation of DBSO (deterministic based structure optimization) design. A solution to the problem of cross section dimension (thickness of lining) and reinforcement design optimization in a concrete structure (tunnel lining) is introduced. The target function is defined as a multicriterial problem and will include economic and ecological aspects associated not only with the production of concrete members but also with their maintenance during utilization. From the mathematical viewpoint, the range of allowable solutions are defined by constraining conditions expressed by relations derived from equations of equilibrium (the solution of optimization calculations for a structure with a Winkler foundation using the finite element method) and the reliability conditions that apply to a reinforced concrete structure.
