The current codes on stability against uplift mainly include two categories:national codes and local codes.Many codes have inconsistent requirements for stability against uplift calculation rules.Some require the use of against uplift design values,some require the use of against uplift characteristic values,some require the use of water buoyancy calculations,and some require the use of water pressure calculations.This paper analyze the similarities and differences between four commonly used standards,and proposes reasonable suggestions based on the principles of stability against uplift mechanics and engineering examples.Two stability against uplift theories,K1 theory(water buoyancy theory)and K2 theory(water pressure theory),are also proposed.Research has found that local codes represented by the Guangdong Specification implement the K1 theory,while national codes represented by the Technical standard for building engineering against uplift implement the K2 theory.Local codes are more in line with mechanical principles.
