Abstract: Based on a museum project along the Beijing-Hangzhou Grand Canal in China, this paper proposes a reverse construction technique for frame columns at beam-slab-column intersections where deformation differences exhibit irregular dynamic changes under loading. Based on finite element analysis of the stress characteristics of the frame columns and their connected beams and slabs, the reinforcement of the frame beams connected to the frame columns is strengthened to meet both the original design requirements and serve as temporary cantilever beams. The main structure outside the frame columns is constructed first, allowing the beams and slabs connected to the top and bottom of the frame columns to deform independently to a stable state. Finally, the frame columns are constructed. This technique effectively solves the quality problems caused by alternating tensile and compressive stresses in the frame columns due to deformation differences at the top and bottom; avoids the need for long-term temporary supports for beams and slabs, reducing construction difficulty and costs; eliminates the additional pressure transmitted to the bottom beams and slabs of the frame columns, improving structural safety redundancy; and accelerates the early interweaving of secondary structures and mechanical and electrical installations, shortening the overall construction period.
