Assessment of data for design situations

(1) In a general manner, imperfections in the geometry of the structure and of structural members should be considered for the most critical design situations during execution. These imperfections should be defined in the project specification. Note 1 Guidance may be found in design Eurocodes. Note 2 For concrete structures, see European Standards established by CEN TC 229 Precast Concrete Products. (2) Any transient design situation should be associated with a nominal duration to be generally...

ENV Annex C informative

Construction loads during casting of concrete C.l Construction loads for profiled steel sheeting (1) The characteristic values of the load densities during casting of concrete on profiled steel sheeting as shuttering are given in Table C.L Note The loads given in Table CI represent the weight of operatives and concreting plant and take into account any impact or vibration which may occur during construction. The given values are not intended to cover excessive impact or heaping of concrete...

General

(1) The self-weight of structural and non-structural elements should be determined in accordance with ENV 1991-2-1, unless more specific data are available. (2)P For the verification of structural members during transport or hoisting, the actual support conditions of these members shall be considered and account shall be taken of mass effects due to vertical and horizontal accelerations, where relevant. Note 1 Guidance is given in ENV 1991-5 for the assessement of vertical and horizontal...

Wind actions w

(1) The characteristic values of wind actions should be assessed in accordance with the methods defined in ENV 1991-2-4 and on the basis of the selected return period. Note 1 Attention should be paid to the fact that on internal walls which will be an internal part of the structure after completion, during construction the external pressure coefficients cpe for free-standing walls may have to be applied. Note 2 In some cases, wind loads may be considered as accidental actions in combinations...
