The paper introduces a new design and construction method of eliminating back-filled joints for superlong reinforced concrete structure, and gives its theoretical basis and application results in engineerings. The method is initiative both in China and abroad, and concerns the design circle greatly.
Keywords: UEA; shrinkage-compensating concrete; jointless design; UEA expansive strengthening zone
