一些桥梁损坏的原因已归咎于结构内部温度的变化。因此,桥梁设计者使用各种方法估算桥梁构件的温度变化,从而确定其应力与应变。 本文介绍一座实验性节段拼装式桥梁现场温度测量的研究结果,并与设计通用的一些温度分布情况进行比较。为了能进行直接比较,对设计通用的温度分布给予修正,使与实测值相一致。最后,从数值比较中,强调与通用方法的一些不同点。 Some of the causes of bridge damage have been attributed to changes in the temperature inside the structure. As a result, bridge designers use various methods to estimate the temperature changes in bridge components to determine their stress and strain. This paper presents the results of field temperature measurements of an experimental segmented bridge and compares them with some general temperature distributions. In order to be able to make a direct comparison, the design of a common temperature distribution to be amended to make consistent with the measured value. Finally, from the numerical comparison, emphasize some differences with the common method.
