【 摘 要 】

Compare calculation data for continuous beam based on elastic system and with account of moment redistribution. Determine reinforcement savings based on the calculation data. Design model enabling the calculation based on elastic system and allowing for its transformation with account of moment redistribution. Identification of locations from where plastic hinges originate and determination of permanent moment values therein. The fracturing probability in the aforementioned cross-sections has been identified. Verification identified fulfillment of deformation conditions. It was demonstrated that implementation of the design model for continuous beam with account of moment redistribution results in reinforcement saving. In calculations with moment redistribution the saving of principal reinforcement in central spans of continuous beam comes up to 13 % as compared to calculation based on elastic scheme.
