摘　　要：为了研究建筑工程隔震装置用橡胶材料高温力学性能,进行了常温和高温下橡胶材料拉伸性能、剪切性能以及压缩性能的力学试验,得到橡胶材料高温下力学性能损伤规律。通过试验数据拟合,得到橡胶材料高温本构关系和相关参数计算公式,为今后隔震装置高温下数值模拟分析提供了真实高温下基本力学性能参数依据。In order to study the mechanical properties of rubber materials used for seismic isolation devices in construction proj-ects under high temperatures,this paper conducted mechanical tests on the tensile,shear,and compressive properties of rubber materials at room and high temperatures,and obtained the dam-age law of mechanical properties of rubber materials at high tem-peratures.By fitting experimental data,the high-temperature con-stitutive relationship and related parameter calculation formulas of rubber materials were obtained,providing a basis for the real ba-sic mechanical performance parameters under high temperature for numerical simulation analysis of isolation devices in the future.
