In the design of RC members, structural performance evaluation is based on concrete that has not been altered. However, in a full-scale structure, there are thermal stresses due to heat of hydration, followed by the effects of drying shrinkage, which determines the seismic performance of RC member.
From the materials side, we have been thinking about how to tackle these effects, and now we have a framework for quantitatively evaluation system by using RBSM. The effects of thermal stress, drying shrinkage, and construction process through restraining process change are very large. We confirmed them assuming 60 years of use for a standard inner wall of a nuclear building.　It is now possible to directly compare the performance of various materials in terms of structural performance.
