四角桅内力计算方法

Calculation method of the internal forces of the quadrilateral mast

四角桅作为一种特殊结构的起重桅,其内力是一空间超静定系统,以某实船的四角桅内力计算为例,介绍一种简便实用的计算方法,可作为船舶设计者借鉴。

As a particular structure of lifting, the quadrilateral mast is a spatial statically indeterminate structural system. Taking the quadrilateral mast in a service ship as an example, this paper sets forth a simple and convenient calculation method of the internal force, which could be taken as reference by designers.
