Experimental Study on Load-Bearing Capacities of Frame-Type Scaffolds Used in Precast Construction
Abstract In precast construction, because the precast beams are broader and the frame-type steel scaffolds need to bear more weight, such as that of the precast slabs and precast beams, the dimensions and load-bearing capacities of the frame-type steel scaffolds are different from those of traditional door-type steel scaffolds. The results of this study show that based on the load-bearing capacities of the five different combined setups of frame-type steel scaffolds used in this study, the horizontal members of the square-type and rectangle-type steel scaffolds are able to enhance the load-bearing capacities of the combined setups of the frame-type steel scaffolds. Therefore, when adopting combined setups of frame-type steel scaffolds, it is advisable to refrain from using only door-type steel scaffolds on construction sites. The ability of jack bases to enhance the load-bearing capacities of frame-type steel scaffolds is not significant. Under the condition of an eccentric load located at one-third of both the x-axis and y-axis, the load-bearing capacity of the frame-type steel scaffolds reduces to 60% of that when no eccentric load is involved. When a lateral force is applied, the critical load of frame-type steel scaffolds decreases with increasing lateral forces.
