【摘要】 通过有限元分析软件,对通讯拉线塔进行了建模,按三种不同预应力值进行地震动力时程分析,得到了地震作用下不同预应力值拉线的内力时程曲线,对比三种预应力值计算的结果,从而选出了地震作用下合理的拉线预应力取值。更多还原

【Abstract】 Modeling of the communication cable tower through the finite element analysis software,value of seismic dynamic time history analysis according to three different prestress,get the curves of the seismic action under the different value of prestressed cable internal force,computational results comparing the three kinds of prestress value,draw the cable prestress reasonable under the action of earthquake.更多还原
