- Abstract
- Building components can be subjected to large thermal gradients in accidental load scenarios such as exposure to fire. Consequently, the thermal and mechanical properties of typical construction materials undergo changes caused by the increase in temperature. Moreover, the modulus of elasticity reduces in value and significantly influences the mechanical response of these components. In this study, a topology optimization procedure is presented for the design of structural components subjected to thermo-mechanical loading, taking into account temperature-dependent thermal and mechanical material properties. Density-based topology optimization with SIMP interpolation is used in combination with the method of moving asymptotes (MMA) as the design updating algorithm. The adjoint method is employed for the computation of the sensitivities required by the MMA. The structural response is governed by a weakly coupled thermo-mechanical finite element model considering non-linear heat conduction. The temperature-dependent material properties are based on Eurocode 2 and the modulus of elasticity in particular is further approximated by an interpolation scheme to obtain a continuously differentiable density function for the stiffness. The proposed topology optimization procedure is demonstrated on a numerical example of the MBB beam considering compliance minimization, which shows the influence of the temperature-dependency on the results.
