EN 1991-1-5 gives design guidance for thermal actions arising from climatic and operational conditions on buildings and civil engineering works.
Information on thermal actions induced by fire is given in EN 1991-1-2.
EN 1991-1-5 is intended for clients, designers, contractors and relevant authorities.
EN 1991-1-5 is intended to be used with EN 1990, the other Parts of EN 1991 and EN 1992-1999 for the design of structures.
In the case of bridges, the National annexes specify whether the general non-linear or the simplified linear temperature components should be used in design calculations.
In the case of chimneys, references should be made to EN 13084-1 for thermal actions from operating processes.
EN 1991-1-5 gives principles and rules for calculating thermal actions on buildings, bridges and other structures including their structural elements. Principles needed for cladding and other appendages of buildings are also provided.
This Part describes the changes in the temperature of structural elements.
Characteristic values of thermal actions are presented for use in the design of structures which are exposed to daily and seasonal climatic changes. Structures not so exposed may not need to be considered for thermal actions.
Structures in which thermal actions are mainly a function of their use (e.g. cooling towers, silos, tanks, warm and cold storage facilities, hot and cold services etc) are treated in Section 7. Chimneys are treated in EN 13084-1.
