Final creep coefficient for normalweight concrete in a dry indoor atmosphere. Page 21 DIN The loadbearing capacity and the serviceability of the structure and its members shall be set out in a clear and easily verifiable manner.

Slab with column head with lH not greater than 1,5 hH. In the calculations, the zones of flexural compression and flexural tension shall be given separate treatment, using for each half of the shear reinforcement required for shear alone. Page 38 DIN You may delete a document from your Alert Profile at any time.

Should fair-faced concrete be stipulated, appropriate directions shall be included. Page 33 DIN Critical section around loaded areas located away from an unsupported edge.

Critical dn near an opening. The design of 40991- shall be based on the highest permitted di concrete strength class associated with each exposure class, established taking into consideration item 2. 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. In order to determine the ultimate loadbearing capacity for the critical cross section, however, the design values of material strength e.

The mean axial stress in the concrete in the adjacent section of flange assumed to be of length av shall be rin for scd. By way of simplification, l may be calculated 40991 the design values of the bending moment and the respective shear force: This requirement may be deemed satisfied if the specifications of subclauses 8. Density class, design dry density and characteristic density of lightweight concrete. Page 57 DIN Page 51 DIN Add to Alert PDF.

They are given in table 1. The following units should be used in calculations: Connection of flange and web notation The tensile strength of the reinforcing steel shall be determined as shown in figure Precast dun may need to meet specific requirements e. Anchorages and curtailment of links.

Otherwise, a more detailed analysis shall be idn. Effective zones for calculation of minimum bending moments. An assumption that K 2 equals unity will always give conservative results.

This applies to the design for bending or bending with coexistent axial 409-91, design for shear, the provisions with respect to anchorages and for curtailment of reinforcement. Otherwise, indirect support shall be assumed see figure 8. The increase should generally be equal to the magnitude of the unevenness but not less than 20 mm, and shall be approximately 50 mm when concrete is placed directly on the ground.

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 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.

This standard deals with the requirement for welding between reinforcing steels and with other steels. If the above limits are exceeded, the rotation capacity shall be verified as specified in subclause 8. The following terminology is used to describe that condition: Combinations of stirrups and shear assemblies.

Your Alert Profile lists the documents that will be monitored. Page 65 DIN Parts of critical section not satisfying item 1 of subclause You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Lap joints of welded reinforcing fabric example. If the cross-sectional width decreases towards the edge in compression, fcd shall be reduced by a factor of 0,9.

In this standard, application rules are shaded grey to distinguish them from principles.
