本文以一座预应力混凝土公路桥梁为研究对象，研究了温度变化对桥梁在两个不同时刻的模态参数的影响。使用落锤和环境振动来激励桥梁。开发了一个有限元模型来支持和验证动态测量。分析和解释了温度变化对结构自振频率的影响。（A）
For the purpose of damage evaluation, this paper studies the effect of temperature variations on modal parameters recorded at two different times in a prestressed concrete highway bridge. A drop weight and ambient vibration were used to excite the bridge. A finite element model was developed to support and verify the dynamic measurements. The effects of temperature change on the structure's natural frequencies are analyzed and interpreted. (A)
