摘　　要：引入新概念组合刚度系数μ，导出测试组合桁架滑移、掀起、挠度和应变的理论公式，与测试值吻合较好。从而提出判别各种交互作用时是否考虑滑移和掀起影响的μ限值作为量化的控制分界值。A new concept of composite rigidity modulus(μ) is given herein.The theoretic formulas of slip,uplift,deflection and strain of composite truss was deduced,the theoretic values are compared with the test ones and the results are very good.The limit values(μ)can be as boundary values shen judging whether considering the effect of ship and uplift during interaction.
