Abstract

Abstract

The climbing stage is a very unfavorable load case for the temporary supports of internal climbing tower cranes. Due to the short action time of loads, the vertical loads will make obvious dynamic effects. Based on measured data the Tower J of Shenwan Huiyun Center with a construction height of nearly 350 m, the characteristics of bending moment and deformation of the temporary supports subjected to loads were analyzed. The characteristics of the structural members of the temporary support were obtained and the dynamic amplification factors of vertical loads were given. The finite element analysis results showed that the simulation results using the dynamic amplification factors were close to the actual measurement results.
