Partial safety factors to determine the resistance at ultimate limit state. The information shown on the drawings shall correspond to that in the structural analysis and shall cover all dimensions necessary for the construction of the members and for checking design calculations.
Connection of flange and web. An assumption that K 2 equals unity will always give conservative results.

Determining areas for partial area loading. DAfStb-Heft gives details regarding the calculation of the equivalent height of isolated compression members. Shear reinforcement in the anchorage zone without transverse compression for bar diameters over 32 mm. Page 38 DIN If the member bracing the compression member forms part of a structure of the type shown in figure 11 bit shall be checked whether the assumption of an inclination of the structure including members with and without a bracing function to the dij axis as specified in subclause 7.
Effective span of a beam or slab. When analysing existing structures, design resistance may also be determined empirically.
Parameters of stress-number diagrams for reinforcement.
CONNIE: SI: Regulations directory : DIN
Transverse tensile forces in a compression zone with confinement at concentrated nodes. Direct and indirect support. Lap joint in tension for bundles of three bars inclusive of a fourth bar. Page 47 DIN Welding operations shall be executed as specified in DIN For 10see page Shear reinforcement for lap joints.
Minimum concrete compressive strength during prestressing with posttensioned or unbonded members at time tj. The independent actions on the structure shall be deemed to be combined, depending on the design situation, making reference to DIN where combinations of actions are to be considered. Special requirements relating to storage of precast elements shall be specified in the drawings and erection instructions. The standards listed above have been consolidated into the new standard series, each Part of which deals with a different aspect.
Page 33 DIN Hardening of grout injected into the sheath ensures the bond between concrete and tendon. The anchorage length, lba, may be determined as follows: For coiled reinforcement, the requirements shall apply to their condition following straightening.

As per thousand; see figure Bilinear stress-strain curve 4 For lightweight concrete, a shall be assumed equal to 0,75 when 0499-1 the curve in figure 23 or the diagram in figure 25, and 0,8 when using that in figure Page 56 DIN Where more than one type of environmental conditions apply, the exposure class with the most stringent requirements shall be taken. Transverse tensile stresses in compression joints. Steel stresses in anchorage zone of pre-tensioned members.
Deviations from application rules are permitted provided they don the principles and achieve serviceability, loadbearing capacity and durability equivalent to those required in this standard.
In monolithic members, the same support reaction may be assumed if the distance of the lower edge of the supported member to the lower edge of the supporting member is greater than the depth of the supported member. Members may be exposed to more than one environmental condition, in which case the exposure classes shall be combined.
The design of members shall be based on the highest permitted minimum concrete strength class associated with each exposure class, established taking into consideration item 2. The values given in table 7 may be used as an approximation.
Plain concrete Reinforced concrete Density class D1,0 to 1 dni 1 D1,2 1 to 1 1 1 D1,4 1 to 1 1 1 D1,6 1 to 1 1 fin D1,8 1 to 1 1 1 D2,0 1 to dni 2 2 9. The depth of the compression zone, x, shall be determined on the basis of the design values of the actions and the material properties. In the absence of other assumptions being made, these effects shall be taken into account by assuming geometrical imperfections see subclause 8.
Ratio of bond strengths of prestressing steel and reinforcing steel. Minimum lap lengths of transverse bars. This may be assumed to be the case if the following conditions apply: The following terminology is used to describe that condition: Design model for calculation of effective eccentricity.
