It may generally be assumed that the conditions in the concrete cover are the same as the ambient conditions to which the dni is exposed.
In such cases, there is no need to determine the structurally indeterminate moment due to prestressing, since the action-effects due to prestressing cannot be distinguished from those due to loading. Alternatively, the provisions of item 3 of subclause Page 39 DIN This may be assumed to be the case if the following conditions apply: Requirements relating to crack control and decompression.
Idn 10 DIN The permitted ratio of nominal diameters of intersecting bars shall be not less than 0, Application of equivalent geometrical imperfections.
For 10see page In this standard, application rules are shaded grey to distinguish them from principles. This does not, however, apply to members of exposure class XC1. These normative references are cited at the appropriate places in the text, and the titles of the publications are listed below. Slab with column head with lH not greater than 1,5 hH.

Representing a mean secant modulus of elasticity at sc R 0,4 f lcm. The minimum cover to ensure adequate corrosion protection and bond shall be as given in table 4 and item 4 above, respectively. Edge reinforcement at the free edges of slabs. These values apply for both compression and tension.
The serviceability analysis ensures the fitness-for-use, and to some extent the durability, of a structure. Page 59 DIN It is obtained by means of equations 65 and Additional shear reinforcement at base of wall.

ein This only applies in cases where the column is not subjected to transverse loads or moments between its two ends and the axial force can be assumed constant over the length of the column. Coefficient aa as a function of anchorage technique. The anchorage zone may be considered uncracked if, at ultimate limit state, the tensile stresses in the concrete taking into account the prestressing force are not greater than concrete tensile strength f ctk;0, If, however, there is a considerable increase in internal forces and moments due to deflections, equilibrium will have to be verified on the basis of the deformed structure second-order theory.
As the voice of the U. Page 36 DIN Simplified moment-curvature relationship for prestressed concrete sections 10 Djn tendons are located externally, the strain between two consecutive points of contact with the structure is to be assumed constant.
Stress-strain curve of reinforcement for global analysis. As a simplification, sp0 may conservatively be assumed equal to spg0. The tensile strength of the reinforcing steel shall be determined as shown in figure Floor joints for shear transmission examples.
However, the stiffness of cross sections after cracking state II may also be used. Coefficients of friction and roughness factors.
Minimum top reinforcement in prestressed members. T-beam with angle of spread of prestressing forces. For coiled reinforcement, the requirements shall apply to their condition following straightening.
