These values may be taken as characteristic values for the above temperature range. Page 39 DIN 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. Connection of flange and web notation Permitted welding processes, joints and applications. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
We have no amendments or corrections for this standard. 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 Page 51 DIN Stress-strain curve for non-linear methods of analysis and strain calculations.
As the voice of the U. It contains provisions relating to design and construction that deviate from ENVand includes provisions from national standards superseded by this standard, 40099-1 this has proved necessary to ensure the loadbearing capacity, serviceability and durability of members designed and constructed according to this standard.
Nodal zone for dun of compression nodes. In this case, it may be assumed that there is sufficient anchorage over l bpd, without need for further investigation.

This standard is not included in any packages. Such methods may be applied in the design 409-91 the unaffected parts of beams and slabs after cracking see subclause rin For dated references, subsequent amendment to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. Otherwise, reinforcing steel shall be classed as being of normal ductility.
Minimum concrete cover for corrosion protection and tolerance on concrete cover. Critical section around loaded areas located away from an unsupported edge. Page 67 DIN This standard deals with the requirement for welding between reinforcing steels and with other steels. Partial safety factors to determine the resistance at ultimate limit state.
Item 9 below shall apply to the design of the column ends. Page 57 DIN Connection of flange and web.

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 design resistance shall be taken into account. Approximate effective spans for calculation of effective flange width 4 Where beams 40991 of variable depth, the web widthbw, in equation 8 may be increased by dimension bv see figure 4.
General shrinkage strain 409-91 normalweight concrete for t approaching infinity. The standards 4909-1 above have been consolidated into the new standard series, each Part of which deals with a different aspect. Subscription pricing is determined by: Arrangement, 40099-1 spacing and minimum concrete cover of bundles of bars.
In keeping with current practice in standards published by the International Organization for Standardization ISOa comma has been used throughout as the decimal marker. In the presence of transverse tensile stresses or transverse cracking, the resulting reduction in compressive strength shall be taken into account.
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.
Maximum reinforcing bar spacing as a function of the design crack width. Design and construction Part 2: Loadbearing joints in two-way spanning precast concrete floors incorporating an in-situ topping example. Other approximate methods are more suitable, however.
Reinforcement ratio for calculation of minimum area of reinforcement. Page 9 DIN Already Subscribed to this document.
Analysis shall be made in each direction in which failure according to second order theory is liable to occur. For undated references, the latest edition of the publication fin to applies. 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.

Connection of secondary beams plan view. Simplified moment-curvature relationship 4 For members subjected to axial force, the simplified moment-curvature relationship shown in figure 10 is only applicable if the reference line by which to determine the moment coincides with the line of action of the axial force. Effective span of a beam or slab. 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.
Minimum diameters of mandrels for welded bent reinforcement. A more accurate analysis will be required if the conditions in equations 41 and 42 are not met.
