Discussion and Suggestion on Improvement in Load Capacity of Taiwan's Steel Scaffolds
Unlike Europe's scaffolds, Taiwan's traditional steel scaffolds load-carrying capacities were usually affected by the factors such as the number of set, number of story, lateral supports when the scaffolds function as a support. Therefore, this research's aim is to develop a new type of scaffolds. Through using the software “ANSYS,” the load-carrying capacity between traditional and new type of steel scaffolds can be analyzed and compared. The improved steel scaffolds, which a new member is added horizontally in the bottom, can solve the problem of lateral supports. As a result, the load-carrying capacity may enhance 1.11 to 2.47 times than before with the increasing number of story. The failure mode of the scaffolds shifts from the traditional in-plane direction to the improved out-of-plane direction. In this way, each story of the improved scaffold system becomes exactly the same powerful. Instead of the damage of the first story often seen in the traditional type, the phenomenon of buckling happens in every story at the same time. To sum up, the improved steel scaffold in this thesis can be considered as a reference to the modification of Taiwan's traditional steel scaffolds.
