摘　　要：多点弹性附着式塔式起重机的塔身结构,在工作和非工作状态下受较大的弯矩、剪力和轴向压力作用。考虑轴向压力对塔身的非线性附加作用,本文从单元体受力分析出发,建立了比较实用的多点弹性附墙支承塔身的非线性变形和内力的计算方法——传递矩阵法。Either in working or non-working conditions, the mast structure of a tower crane with multiple elastic attachments will bear considerable bending moment, shear and axial compression, with the additional actions of axial compression on the mast taken into account and based on the analysis of an element under stress, this paper presents a practical way to calculating the nonlinear deflection and internal forces of the mast attached to the wall with multiple elastic attachments, i. e, the transfer matrix method.
