Minimum lap lengths of transverse bars. Page 59 DIN In order to determine the ultimate loadbearing capacity for the critical cross section, however, the design values of material strength e. 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 44099-1.
Such methods may be applied in the design of the unaffected parts of beams and slabs after cracking see subclause Page 55 DIN 40999-1 Parameters of stress-number diagrams for prestressing steel. Hfd does not need to be taken into consideration when designing vertical bracing members. Page 62 DIN Exposure classes 1 2 Description of environment 3 4 Minimum concrete 409-91 class Class Examples where exposure classes may occur 1 No risk of corrosion or attack X0 No risk of attack Members without reinforcement in a non-aggressive environment e.
Clear minimum spacing for pre-tensioned members.

In case of doubt, the German-language original should be consulted as the authoritative text. Cracking shall be taken into account when determining the anchorage force to be sustained 40991- the prestressing steel cf. Page 31 DIN Slab with column head with lH not greater than 1,5 hH.
These values may be taken as characteristic values for the above temperature range. Page 63 DIN Final creep coefficient for normalweight concrete in a dry indoor atmosphere. You may delete a document from your Alert Profile at any time.
The following units should be used in calculations: 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 36 DIN Partial safety factors to determine the resistance at ultimate limit state.
Page 33 DIN Parts of critical section not satisfying item 1 of subclause Special requirements relating to storage of precast elements shall be specified in the drawings and erection instructions. Lap joints of welded reinforcing 40999-1 example.

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 figure Connection of secondary beams plan view. Simplified moment-curvature relationship for prestressed concrete sections.
Minimum concrete compressive strength during prestressing with posttensioned or unbonded members at time tj. 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.
The tensile strength of the reinforcing steel shall be determined as shown in figure Page 39 DIN Top and bottom corner reinforcement. Arrangement of punching shear reinforcement. Otherwise, a more detailed analysis shall be made. Page 54 DIN
