Strengthening by temperature induction
Structural concrete components with
reinforcement glued in slots
Strengthening structural concrete members by augmenting cross-sections or gluing supplementary reinforcement onto surfaces or into slots yields benefits resisting service loads. Since members are strengthened when loaded and deflected, the self-weight is still borne by the initial cross-section only. In statically indeterminate systems, temperature induction applied during strengthening enables to activate the total cross-section to carry the dead load. Due to a linear, vertical temperature gradient, the concrete member then faces a constraining moment which locally compensates the bending...
