随着近年来城市建设的发展,尤其是多层住宅建筑和高层公共建筑的发展,塔式起重机的重要性和优越性已普遍为人们所认识。为适应各种施工现场的需要,固定式塔式起重机蓬勃发展起来。但是,这种塔式起重机抗扭刚度弱,扭转变形大,在使用中是一个较普遍的问题。这主要是由于扭转变形计算这一甚为重要的计算项目,往往被忽视和遗漏。下面,我们将简要地讨论固定式塔式起重机的扭转变形计算问题。一、固定式塔式起重机塔身扭角的计算塔式起重机在回转制动或启动时,所引 With the development of urban construction in recent years, especially the development of multi-storey residential buildings and high-rise public buildings, the importance and superiority of tower cranes have been generally recognized. In order to meet the needs of various construction sites, stationary tower cranes are booming. However, this tower crane torsion stiffness is weak, large torsional deformation, in use is a more common problem. This is mainly due to the calculation of torsional deformation, a very important calculation item, often overlooked and omitted. Next, we will briefly discuss the fixed tower crane torsional deformation calculation. First, the fixed tower crane tower torsion angle tower crane in the rotary brake or start, cited
