Anti-seismic Design, Diagnostics and Reinforcement for Concrete Structures

Part of the cSUR-UT Series: Library for Sustainable Urban Regeneration book series (LSUR, volume 4)

In the interest of having performance-based design offer more transparency to clients and taxpayers, performance assessment methods occupy a central position from the viewpoint of structural mechanics and engineering. This rational way of assuring the overall quality of infrastructures may create cost-beneficial design and construction that exactly satisfy several requirements assigned to engineers. Life-cycle-based diagnostics of structures is required explicitly by societies and organizations. Furthermore, there is emerging a greater need to verify the remaining functionality of damaged facilities in order to extend their service life. To meet these challenges, it is desirable to formulatean explicit system for the prediction and simulation of structural life serviceability and safety under specified loads such as earthquake and ambient conditions

In this chapter, the author proposes an integrated platform of solid mechanics and hydrothermal dynamics of materials and structures with multi-scales of referential control volume on which each physicochemical factor is applied. In more detail, a constitutive model is discussed with regard to cracking in reinforced concrete (RC) elements, and a mathematical overlay of hydrothermal state variables is presented for multiscale and multichemical mechanical coupling with soil foundation. Recent application of the multi-scale approach to practical problems is introduced for urban regeneration, and the direction of future development is discussed as an integrated knowledge-base of structural concrete and soil foundation
