Research on the Non-Planar Deformation Behavior of Reinforced Concrete Components Based on Size Effect

The section deformation distribution of reinforced concrete components is nonlinear due to the size effect. Existing analysis models such as plastic hinge and truss element are based on plane cross-section assumption. cannot be accurately simulated. Therefore, in this paper, non-planar strain functions sections established. law influence geometrical characteristics load distributions beam ends analyzed. quantitative method established between size, position, shear span ratio, sections. finite simulation test results show that shape given paper can describe axial different along height width behaviors mechanical properties interface connection accuracy improved structural multiscale simulation.
