摘要
推导了大位移下空间桁架全量形式的平衡方程和考虑位移修正的刚度矩阵。
Space trusses'equation of equilibrium with all - variables form and stiffness matrix with displacement amended under large displacement are deduced. Numerical example illuminates that the mathod presented in this paper can analyse the geometrically nonlinear problems of space trusses with more accurately.
