Theoretical stress-strain curve of prestressing steel for section design. Analysis shall be made in each direction in which failure according to second order theory dih liable to occur. Page 7 DIN Page 55 DIN Page 47 DIN In the absence of other assumptions being made, these effects shall be taken into account by assuming geometrical imperfections see subclause 8.

When using ribbed fin not more than 12 mm in diameter, fbp should be determined experimentally. Connection of secondary beams plan view.

This does not, however, apply to members of exposure class XC1. Shear in cross sections of variable effective depth. Stress-strain curve of reinforcing steel for section design.

Results obtained by computation e. Possible distribution of strain in reinforcement and prestressing steel at the ultimate limit state 4 In cross sections remaining in compression, the compressive strain at point C shall be not greater than ec2 or elc2 from table 9 or Page 8 DIN Page 56 DIN Parabolic-rectangle stress-strain curve 2 The design unconfined concrete compressive strength, fcd, obtained by means of equation 67shall be used as the basis for design for the ultimate limit state: Sections for analysis of punching shear reinforcement.

Page 27 DIN Dn, 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.

Effective span of a beam or slab 7 Where beams or slabs are directly supported, the load from the supported member is counteracted by compression at its lower edge. Characteristic values of strength and strain for normal-weight concrete. Page 23 DIN The loadbearing capacity and the serviceability of the structure and its members shall be set out in a clear and easily verifiable manner. Subscription pricing is determined by: Determining areas for partial area loading. Tying system providing for accidental actions floor plan.

Approximate effective spans for calculation of effective flange width. VRd,ct as the design shear resistance of members without shear reinforcement; as the design shear resistance, limited by the capacity of the shear reinforcement; VRd,sy VRd,max as the design shear resistance, limited by the strength of the struts. Page 61 DIN However, z shall be not greater than d — 2 cnom c nom being the nominal concrete cover of the longitudinal reinforcement in the compression zone.

Page 33 DIN The layout drawings shall also include details of the bearing depths required for assembly purposes and the supports required by the precast elements.

In the above, a partial safety factor, gR, of 1,3 for permanent and temporary design situations and fatigue analysis or 1,1 for accidental design situations for the 499-1 resistance shall be taken into 40991. As the voice of the U. Lap joints of welded reinforcing fabric example.

Page 35 DIN 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.

Compressive stresses shall be given negative signs diin equation The loadbearing capacity of the overall cross section does not need to be assumed to be less fin that of the webs of height h and with a strain distribution as shown in figure Design model for calculation of effective eccentricity. The following units should be used in calculations: This standard is not included in any packages.

Design shall be carried out in accordance with the principles of this standard. Loadbearing joints in two-way spanning precast concrete floors incorporating an in-situ topping example.
