轴向力对梁弯曲振动频率有一定影响。根据这一特点 ,可以期望通过检测预应力钢筋混凝土梁的自振频率来了解其预应力情况。通过理论分析和实验 ,对预应力和预应力钢筋混凝土梁自振频率间的关系进行了初步探讨
The axial force has a certain influence on the bending frequency of the beam. According to this feature, it is expected that the prestressing condition can be known by examining the natural frequencies of prestressed reinforced concrete beams. Through theoretical analysis and experiment, the relationship between prestressing and natural frequency of prestressed reinforced concrete beam
