以“哈夫式”抱瓦连接这种超大型塔式起重机塔身标准节常见的连接方式为例,介绍了一种通过有限元弹塑性分析的方法考查构件在应力集中处局部塑性屈服后的承载能力,对这类结构的设计计算具有一定的参考价值。
In this paper, a typical connection method of “Huff-type” hull-and-tile connection tower crane standard section is taken as an example to introduce a method of finite element analysis of elastic-plastic analysis of component plastic stress in the local plastic yield After carrying capacity, the design of such structures has a certain reference value.
