摘　　要：为验证组合桁架有限元模型的准确性，寻求组合桁架内力和变位的分布规律，提供实际设计依据，对两榀测试组合桁架的内力、滑移、掀起和挠度进行电算和实测，电算值与实测值吻合良好。In order to prove the accuracy of finite element model of the composite truss,seek the distribution regulauity of the intemal force and displacement of composite truss,and provide basis for practial design,calculation and testing measrement for the intemal force,slip,uplift and deflection of two test composite trusses were done which prove that calculation values and the test values are corresponding well.
