| 中文摘要: |
| 基于隔震橡胶支座竖向抗拉能力不足的缺点，对隔震橡胶支座拉伸性能及拉伸后力学性能进行试验研究。结果表明：支座屈服拉应力根据橡胶剪切模量不同可达2. 0～2.7 MPa，极限拉应力约为5 MPa，极限拉应变在350%左右；支座经单轴拉伸后，常规力学性能变化不大，且支座竖向压缩极限性能和水平剪切极限性能也能够较好地保持，体现出较好的功能性和安全性。 |
| 英文摘要: |
| Based on the shortcoming of insufficient vertical tensile capacity of the isolation rubber bearing，the tensile properties and post-stretching mechanical properties of the isolation rubber bearing were experimentally studied. The results showed that the yield tensile stress of the bearing could reach 2. 0～2.7 MPa according to the shear modulus of the compound，the ultimate tensile stress was about 5 MPa，and the ultimate tensile strain was about 350%. After uniaxial tension，the conventional mechanical properties of the bearing changed little，and the vertical compression limit and horizontal shear limit properties of the bearing could be well maintained，demonstrating good functionality and safety. |
