ISO/TR 9492:1987

Bases for design of structures — Temperature climatic actions

Is intended to be a guideline for code-writers. Can be applied to the determination of unfavourable characteristic values of temperature difference due to temperature climatic actions which are taken into account in static analysis of structures for which the variation of temperature within the cross-section can be treated as linear. Is not applicable to massive structures (dams, retaining walls, tunnels, bridge piers ets.). For condideration of such structures it may be necessary to take into account non-linear distribution ot temperature through the body of the massive structural elements.
