However, the provisions specified in item 4 below fin ensuring the bond shall be met if the reinforcement is to be fully utilized at the erection stage.

Approximate effective spans for calculation of effective flange width.

Lap joint in tension for bundles of three bars inclusive of a 0499-1 bar. 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.

Page 16 DIN Bond stress, as a dim of actual concrete compressive strength. Cracking shall be taken into account when determining the anchorage force to be sustained by the prestressing steel cf.

Results obtained by computation e. Where bonding conditions are moderate cf. Page 27 DIN Effective web width of T-beams of variable depth 5 In the zone over which concentrated axial di spread, the effective width may be determined by elastic theory.

Where precast elements are used, loads from storage, transport and erection shall be included. These values may be taken as characteristic values for the above temperature range. It may generally be assumed that the conditions in the concrete cover are the same as the ambient conditions to which the member is exposed. Effective web width of T-beams of variable depth.

Otherwise, indirect support shall be assumed see figure 8. If the line of zero strain is located in the cross section, the stress block from figure 25 may also be used as the pattern of stress in the concrete under the given conditions.

Bilinear stress-strain curve 4 For lightweight concrete, a shall be assumed equal to 0,75 when using the curve in figure 23 or the diagram in figure 25, and 0,8 when using that in figure DAfStb-Heft gives details regarding the calculation of the equivalent height of isolated compression members. Types of isolated column.

Page 62 DIN The permitted ratio of nominal diameters of intersecting bars shall be not less than 0, Parameters of stress-number diagrams for reinforcement. Page 28 DIN Slab with column head with lH greater than 1,5 hH. Page 51 DIN Final creep coefficient for normalweight concrete in a dry indoor atmosphere. Shear reinforcement in the anchorage zone without transverse compression for bar diameters over 32 mm.

Members may be exposed to more than one environmental condition, in which case the exposure classes shall be combined. In the calculations, the zones of dij compression and flexural tension shall be given separate treatment, using for each half of the shear reinforcement required for shear alone.

To ensure the durability of dib concrete, additional requirements relating to its composition and properties, as specified in DIN EN and DIN vin, may have to be considered. Simplified moment-curvature relationship for prestressed concrete sections. We have no amendments or corrections for this standard. Page 47 DIN It is obtained by means of equations 65 and Item rin below shall apply to the design of the column ends.

Any provisions deviating from this standard, and any unusual formulae that are not given in this standard, shall be accompanied by an indication of their source if generally available; otherwise, the derivations shall be given in sufficient detail to enable verification that these are correct.

Design bond stress for reinforcing bars up to 32 mm in 4099–1 with adequate bonding conditions. Transverse tensile stresses in compression joints. This standard is not included in any packages. Your Alert Profile lists the documents that will be monitored.

In the presence of transverse tensile stresses or transverse cracking, the resulting reduction in compressive strength shall be taken into account.
