There are many structural problems when the scaffolding frame is applied to a construction site contractor may use a used pipe or buckled pipe which they lended them from commercial firms without any inspection of those materials even though they have been used and exposed to weather for a long times. Therefore, they should be checked of their current capacity, comparing with the original one so that construction contractor can apply their capacity to a temporary frame depending on the site situation against collapsion of those. This study is mainly focused on the behavior of a scaffolding frame using prebuckled pipes. Additionally, standard frame with bracing and without bracing case are also tested for comparing with the prebuckled case. Prebuckled case has its capacity less approximately 20 % than the standard frame.
