Abstract: This study focuses on the critical loads of scaffolding with the anchor rods, plank and inner knee brace under concentric and eccentric loads during construction. The steel rebar is used in place of the patent anchor rod in this research. This study shows that the critical load of the scaffolding increases by 1.5 times when the anchor rods of length of 30 cm are used on two sides of every story of scaffolding. The critical load increases by 4 times when the scaffolding has both anchor rods and plank. The critical load of scaffolding with the anchor rods placed on each story is twice as large as the load with anchor rod added every two stories. In addition; the failure mode of the structure is also transformed from the in-plane direction to the out-of-plane direction. The 30 cm long anchor rod, a steel bar of grade 3, provides a good lateral restraint to the scaffolding. The setup plank can significantly increase the critical load of the scaffolding. The critical load increases by 1.5 times under the concentric load, and increases up to 2.2 times under the TL/4 eccentric load defined as the load applied a quarter distances from the end. The anchor rods and the planks are suggested to install in a scaffolding to improve stability, especially under eccentric loads during construction.
