In the paper there are discussed the problems dealing with the calculation of transmission length, development length and anchorage length in prestressed concrete elements according to codes: Model Code 1990, 2010; PN-EN 1992-1-1:2008. Additionally the codes DIN 1045-1 and ACI 318 were taken into consideration. Calculation example for prestressed concrete tank wall panel under construction, has pointed the serious difference in obtained values of transmission length from experimental investigation and from codes relationship.
