【 摘 要 】

The multi-layer reinforced concrete formwork support system is a comprehensive structural system considering the formwork, structural beam and steel plate and steel pipe support. The demolition and turnover of the formwork support are affected by the time-varying of the concrete structure and the randomness of the construction. In this paper, the multi-layer formwork support system of the 2# building project of a real estate development project is field tested, and the multi-layer formwork support system is obtained during the construction process. The time-course curve of the axial force of the rod and the concrete strength growth curve are analyzed. The force transmission mechanism and load transfer law of the multi-layer formwork support system are analyzed.
