Improved prediction model for time-dependent deformations of concrete: Part 6-Simplified code-type formulation

The complexity of the full BP-KX model for creep and shrinkage prediction presented in the previous five parts is due to the large number of influencing factors taken into consideration rather than an inherent complexity of the theory. However, a sophisticated model with all these factors is needed only for the design of special structures, such as bridges of a record span, buildings of a record height, or nuclear reactor structures. For most practical applications, many of the factors can be eliminated and can be fixed at their typical values. This yields a simplified BP-KX model which is presented in this last part. The simplified model should suffice for many practical applications and is suitable for standard code-type recommendations of engineering societies. The design of every structure can begin with this simplified model, and only if the effects of creep and shrinkage are found rather significant is analysis according to the full BP-KX model necessary.
