This paper compares the calculation formulas of pre-stress friction loss in domestic and foreign codes, establishes a simplified formula using Taylor series expansion method, and proposes a convenient and reliable method for calculating pre-stress friction loss, and statistical analysis and reference of actual measured data. The domestic and foreign regulations put forward suggestions on the value of the friction coefficient of large-span and high-rise prestressed concrete structures.
