A practical multi-scale response sensitivity analysis method for reinforced concrete structures

This paper extends a practical multiscale response sensitivity analysis (MSRSA) method to study the sensitivities of nonlinear reinforced concrete (RC) structures. The MSRSA method is based on an efficient and accurate method, the direct differentiation method, and was used for concrete material. For RC structures, the concrete and steel are simulated with the mesoscopic discrete element (DE) model and macroscopic finite element (FE) plasticity...
