| Abstract: | In the construction of high-rise and long-span reinforced concrete structures, many safety accidents result from the defect of the analysis and erection of scaffold. To solve the problem, an accurate FEM model is adopted to analyze the scaffold and is compared with the common simplified models in practice. The comparison shows that the simplified models may do give unsafe results and so several suggestions for improvement are put forward. |
