Abstract

Abstract

Temporary supports transfer loads from tower cranes to permanent structures, which is an important temporary structure in the construction of super high-rise buildings. Two different internal climbing tower cranes and temporary supports used in the construction of two super high-rise buildings were taken as research objects. By finite element calculations, the characteristics of temporary supports subjected to various loads were analyzed. And the position where the most unfavorable loads occured and the corresponding vertical load-distribution coefficient were given. Some measures were proposed to reduced the distribution unevenness of vertical loads on temporary supports of external suspended tower cranes,and the effectiveness was analyzed.
