Quality Reliability Control of Reinforced Concrete Structures during Construction

It is shown by engineering investigation that structure failures during construction are larger portion of which a number of structure failures occur.In order to seek an effective method turn this condition,the time-dependent quality equation of the structural element and its material property during construction is proposed.It is recommended that this equation and the quality equation specified by the current code should be coordinated to control the structural quality,so the full quality control of the total course for the structural element and its material property can be realized.
