Abstract: To solve the problems of concrete piston striking cylinder and pumping insufficiency caused by the mismatch between varying loads and system's open-loop control property, the optimal model of concrete pumping displacement control was built.To be precise, the displacement control signal parameters were taken as control variables, and the location parameter of the main cylinder's displacement …

Layout design of reinforced concrete structures using two

May 24, 2012 · Two-material topology optimization with strength failure constraints. We assume the design domain Ω des of a reinforced concrete structure is occupied by either concrete or steel (see Fig. 2).Denoting the concrete region and the steel region by Ω c and Ω s, respectively, it holds that Ω c ∪ Ω s = Ω des and Ω c ∩ Ω s = ∅. To obtain a mathematical description of the structural
