Abstract. The following paper presents numerical analyses and laboratory tests used for analyzing the impact of exploitation damage to the main structural members of the scaffolding frame system. The presence of inevitable defects reduces the strength of material compared to the theoretical strength. Numerical analysis preceded by own laboratory research allows you to describe precisely the behavior of the element. Performing a series of calculations gives information on the impact of the damage size and location on the bearing capacity of the scaffolding frame.

“…Zhang et al [11][12][13] conducted research on cuplock-type scaffolds using the probability-based design method. Beale et al [14][15][16], Ao et al [17], Yue et al [18] and Liu et al [19][20] conducted systematic studies on stability capacity and design method of multi-span coupler-type steel-tube scaffold using experimental research and numerical analysis. Engineering accident analysis shows that unstable connection performance of joints is the main cause of scaffold collapse [21].…”

A mortise-tenon steel-tube scaffold, a new steel-tube scaffold, was presented based on ancient mortise-tenon joint in wood structure. Because of better joint mechanics and higher bearing capacity than coupler-type steel-tube scaffold, this new scaffold possesses good market potential. Based on an analysis of the bearing mechanism, a finite element numerical analysis model for the mortise-tenon steel-tube scaffold was established in this study, which was validated as reasonable and accurate by experiment data. Influencing laws of storey height, vertical member interval, X-bracing layout, overall structure height, height of bottom horizontal tube, and height of upper cantilever bar on the mortise-tenon steel-tube scaffold were determined through parameter analysis. A simplified calculation formula of ultimate bearing capacity was established, which verified by FEM results and test data. Research results provide important references for future in-depth studies and engineering applications of the mortise-tenon steel-tube scaffold.

“…Romera et al [13] observed that many construction accidents are caused by deficiencies in the project design phase. Beale [14] published a review of scaffolding and falsework structures performed over the last 40 years; this review also discussed the finite element modeling and testing procedures of scaffolds and provided recommendations for modeling connections and different loads on scaffolding systems. Kim and Teizer [15] developed a rule-based system that could automatically plan scaffolding systems for pro-active management in building information modeling.…”

ABSTRACT:The collapse of scaffolds can bring about substantial damage and economic loss. In recent years, over hundreds of people died and an even greater number have been injured because of inadequate scaffolding system designs. In this study, the effects of truss height and number of tie bars on the structural behavior of suspended scaffolding systems were experimentally investigated. Three full-scale scaffolding systems with truss heights of 30, 45, and 60 cm were tested in the laboratory. Each system included a wooden floor, steel purlins and trusses. The number of steel tie bars connected to the systems was also varied. A load transmission system was placed in these experimental systems to distribute single loads to the center of a specific area in a step-by-step manner using a load jack. After each load increment, the displacement was measured by means of linear variable differential transducers placed at critical points of the wooden floor, purlins, and trusses. This test was repeated for all systems and under all system conditions. The test results revealed that displacement increased exponentially in scaffolds with truss heights of 30, 45, and 60 cm without tie bars. Under the same load, systems with truss heights of 60, 45, and 30 cm revealed displacements of 8.8, 12.1, and 23.3 cm, respectively. The results of this work demonstrate that the number of tie bars and truss height considerably affect the structural behavior of scaffolding systems. Our findings further suggest that a scaffolding system with 60 cm-high truss and two tie bars presents optimal safety and cost-savings.
