Abstract
The research works undertaken in this thesis were focused on a comprehensive exploration of steel falsework systems, with a particular emphasis on the behavior of ringlock and cuplock systems. The study involved an extensive analysis of joint behavior and system performance, utilizing both experimental and numerical approaches. Various factors influencing joint behavior and load-bearing capacity were thoroughly investigated under different loading scenarios. The investigation examined the effects of loading direction, inducing varying moments on the joints, including major bending under different loading cases such as gravitational and uplift forces, as well as minor axis bending scenarios. The impact of the number of locking hammer blows on the joint capacity was explored, and joint classifications were conducted based on international codes of practice. Additionally, the study delved into the influence of steel tube slenderness on the behavior of ringlock joints.
Further investigation covered the examination of falsework systems under vertical loading, considering factors such as spigot joints, edge conditions, load eccentricity, and the role of the bracing. The research ended up in the reevaluation of the effective buckling length factors normally used in these systems based on their location in the system, with comparisons against established standards. The research outcome includes the development of a comprehensive finite element simulation framework that captures the intricate behaviors exhibited by steel falsework systems. This framework integrates various elements to provide a complete representation of system performance.
The findings from this study offer valuable insights into the complex behavior of steel falsework systems. The research spans both experimental and numerical investigations, yielding conclusions about joint behavior, load-bearing capacities, effects of various factors, and the development of advanced simulation models. These findings contribute to the understanding and design optimization of steel falsework systems, providing critical insights for the engineering community.
