Abstract: To address the high construction risks associated with traditional active support systems (ASSs) for integral climbing construction platforms (ICCPs) due to their inability to detect extension/retraction travels and loads from the massive ICCP structure, this study investigates a self-sensing method for load and travel in ASSs suitable for high-rise ICCPs. Specifically, it focuses on the hardware of the tool-type ASS support component with integrated load and travel self-sensing capabilities, the framework of the ASS monitoring and control system, and key aspects of ASS status evaluation and analysis. Taking a 356-meter-tall super-high-rise construction project as a case study, monitoring tests and research on application procedures for tool-type ASS are conducted. The results indicate that this method enables self-sensing of the load on the ASS load-bearing pins, as well as the identification and control of extension/retraction travel and support status. It enhances the safety of ICCP construction and provides a foundational technological basis for transitioning ICCP toward autonomous, intelligent, and safe, efficient construction. The research and development of this method can be extended to various fields, including climbing formwork equipment, tower crane support structures, and underground engineering support systems.
