Layout optimization of steel reinforcement in concrete structure using a truss-continuum model

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 5,   Pages 669-685 doi: 10.1007/s11709-023-0963-0

Abstract: This approach combines a minimum compliance objective function with a hybrid truss-continuum model.To fully utilize the tensile strength of steel and the compressive strength of concrete, the optimizationsensitivity of steel in a concrete–steel composite is integrated with the average normal stress of aClear steel trajectories of SRC structures can be obtained using both methods.M-BESO facilitates a fully digital workflow that can be extremely effective for improving the design of steel
