桁架杆 meaning in Chinese

truss bar
truss rod

Begin for the problem that some parameters can not be simulated exactly before , according to the data observed on - site , the dynamic elastic modulus and the elastic modulus of the spar of the rooftop has been reckoned in reverse with the function of ansys optimum . design
首先，针对以往计算中，部分模型参数模拟不准确的问题，根据现场实测数据，运用ansys优化功能对混凝土动弹模和屋顶桁架杆的轴向刚度进行了反演，用反演的参数结果建立模型进行模态分析与实测数据符合较好。
