钢立柱的刚度对内支撑构件轴力的影响分析

Analysis of the Influence of the Stiffness of Steel Column

文中结合基坑工程实际情况,重点分析了钢立柱的刚度和竖向位移对内支撑构件轴力的影响。结果表明,钢立柱的刚度与内支撑构件轴力有密切关联,随着钢立柱的刚度增大,各个支撑水平方向的轴力更为接近,杆件的受力趋于平衡状态。

Combined with the actual situation of the foundation pit engineering,the analysis of the stiffness and vertical displacement of the internal support member shaft force of the steel column.The results show that the stiffness of steel column is closely related to the shaft force of the internal support member.With the increase of the stiffness of steel column,the axial force of each horizontal support is closer,so that the force of the rod tends to balance.
