Minimum lap lengths of transverse bars. When analysing existing structures, design resistance may also be determined empirically. Page 31 DIN The following terminology is used to describe that condition: Coefficient aa as a function of anchorage technique. However, the provisions specified in item 4 below for ensuring the bond shall be met if the reinforcement is to be fully utilized at the erection stage.
Possible distribution of strain in reinforcement and prestressing steel at the ultimate limit state 4 In cross sections 40999-1 in compression, the compressive strain at point C shall be not greater than ec2 or elc2 from table 9 or Page dinn DIN Page 16 DIN Stress-number diagram for reinforcing and prestressing steel.
All dimensions are in millimetres. Design model for analysis of punching shear resistance. The following shall apply for b w,nom where there are adjacent ungrouted or unbonded tendons: Possible distribution of strain in dkn and prestressing steel at the ultimate limit state. Minimum diameters of mandrels for welded bent reinforcement.
Direct and indirect support. Simplified moment-curvature relationship for prestressed concrete sections. Characteristic values of strength and strain for normal-weight concrete. This also applies to reinforced concrete walls connected to slabs. In the absence of other assumptions being made, these effects shall be taken into account by assuming geometrical imperfections see subclause 8. Page 43 DIN 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, Simplified moment-curvature relationship for prestressed concrete sections 10 Where tendons are located externally, the strain between two consecutive points of contact with the structure is to be assumed constant.
Page 24 DIN Arrangement, minimum spacing and minimum concrete cover of bundles of bars.

The loadbearing capacity and the serviceability of the structure and its members shall be set out in a clear and easily verifiable manner. Parts of critical section not satisfying item 1 of subclause The most unfavourable value shall be assumed. Density class, design dry density and characteristic density of lightweight concrete.
The loadbearing capacity of the overall cross section does not need to be assumed to be less than that of the webs of height h and with a strain distribution as shown in 4099- Special requirements relating to storage of precast vin shall be specified in the drawings and erection instructions.
Coefficient to determine equivalent span. Drying shrinkage strain of normalweight concrete for t approaching infinity.
Zone 4099- which reinforcement is effective. Final creep coefficient for normalweight concrete in an external humid atmosphere. Page 8 DIN VRd,ct as the design shear resistance of members without shear reinforcement; as the design shear resistance, limited by the djn of the shear reinforcement; VRd,sy VRd,max as the design shear resistance, limited by the strength of the struts. For coiled reinforcement, the requirements shall apply to their condition following straightening.
These may be isolated compression members see figures 11 a and 11 b or compression members forming part of a structure but which may be classed as isolated compression members for the purpose of analysis as specified in items 12 and 3 of subclause 8.
