Main arch ring with strong skeleton, temperature effect, closing temperature, stress, deflection.Abstract
In this paper, a finite element model of the main arch ring of the strong skeleton is developed in order to analyse the stress and deflection response of the strong skeleton under the action of uniform temperature during the lifting stage. Uniform temperature action was found to have a significant effect on the stresses and deflections of rigid skeletal stringers. The effect of the huddle on the stress and deflection of the skeleton at the non-design reference temperature was further investigated, and the results showed that the changes of the stress and deflection of the skeleton were directly proportional to the relative temperature difference (the difference between the huddle temperature and the design reference temperature).In addition, a reasonable value for the jointing temperature was analysed, and it was suggested that a value of 2℃slightly lower than the average annual temperature be used as the jointing temperature.
