Abstract: The increasing frequency of earthquakes has had a significant impact on citizens' property and life safety. In order to reduce the losses caused by earthquakes, the research is conducted from the perspective of structural layout of building shock absorption. This paper realises the synchronous optimisation of the layout position and damping coefficient of viscous fluid dampers under the actual ground motion. The ramp model in the density method of structural topology optimisation is used to continuously process the discrete design variables in the objective function of the optimisation problem, and then the moving asymptote method is used to solve the optimisation problem. The results show that different damper groups will lead to great differences in project cost; when a single type of damper is selected to participate in the layout optimisation, the required total damping coefficient is 23,020 k Nm⁻¹s. When two types of dampers are used to participate in the layout optimisation, the required total damping coefficient is 20,550.8 k Nm⁻¹s. The cost of a single group of dampers is significantly higher than that of two groups of dampers.
