Abstract

Abstract

Based on a long-span and complex steel frames building with inclined pillars in a relic protection project, the finite element model was constructed to simulate the whole process of construction. Based on the actual situation of the site, considering the influence of the original soil piled up, the model was optimized and the construction process was adjusted, and the prestressed three-stage tensioning scheme was adjusted to a two-stage tensioning scheme; the stress in crucial sections of inclined pillar support system and the displacement of pillar tops were obtained during the construction process of the structure and compared with the measured data of the corresponding measuring point. The results showed that the theoretical values were in good agreement with the measured values. The crucial section stress and pile top displacement of each members were within the allowable range. The two-stage tensioning scheme was reasonable and could ensure the safety of the construction process of the structure. The simplified model of the piles could reflect the internal forces of the members of the inclined pillar support system and the displacement of the pile tops displacement to a certain extent, and had certain practicability.
