In keeping with current practice in standards published by the International Organization for Standardization ISOa comma has been used throughout as the decimal marker. The horizontal forces, H fd, shall be regarded as independent actions and shall not be further reduced by combination factors since these are already taken into account in the vertical axial forces. Torsion notation 40099-1 equivalent systems.

Reinforcement ratio for calculation of minimum area of reinforcement.

When using ribbed wires not more than 12 mm in diameter, fbp should be determined experimentally. Page 28 DIN These values apply for both compression and tension.

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.

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 59 DIN Alternatively, resistance to wear may be improved by increasing the concrete cover, in which case cmin should be raised by about 5 mm for exposure class XM1, 10 mm for XM2 and 15 mm for XM3. The capacity of the structure to sustain loads and transfer them internally shall be verified using a suitable method e.

Permitted welding processes, joints and applications. Page 45 DIN Reduced depth of cross section for a separate analysis in y – plane for e 0z greater than 0,2 h.

Anchorages and curtailment 4099- links. Hfd does not need to be taken into consideration when designing vertical bracing members. Alternatively, the provisions of item 3 of subclause Page 54 DIN Simplified moment-curvature relationship for prestressed concrete sections. Page 63 DIN Page 68 DIN It may be given a value of 0,95 spg0 for conventional buildings.

Hardening of grout injected into the sheath ensures the bond between concrete and tendon. If the above limits are exceeded, the rotation capacity shall be verified as specified in subclause 8. As the voice of the U. The values given in table 7 may 4099-1 used as an approximation. Characteristic values of strength and strain for lightweight concrete.

Item 9 below shall apply to the design of the column ends. 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. In order to determine the ultimate loadbearing capacity for the critical cross section, however, the design values of material strength e.
