Abstract:

In the existing analytical cable elements, the temperature effects are considered, with the unstressed length being calculated according to the temperature variation first and being taken as the reference state for the static strain. Therefore, the temperature strain and the strain by the static loads have different reference states. Based on Irvine's work, a temperature effect correction for an analytical cable element is made to overcome this problem. An example shows the rationality of the correction.
