| 摘要: |
| 为了将隔震技术推广应用至低层村镇建筑,研发一种造价低廉、制造工艺简单的层间黏结废旧轮胎隔震垫（LBSTP）。选用3种高韧性黏结剂,以层间黏结的方式对废旧轮胎隔震垫（STP）进行增韧补强,并开展黏结破坏试验和力学性能试验。观察废旧轮胎黏结剥离与黏结剪切的破坏现象,结合黏结破坏机制,对LBSTP力学性能进行分析。结果表明:V-SC2000黏结剂强度最高而延展性最差,鱼珠牌万能胶强度最低而延展性最好,且与压剪试验中LBSTP角部翘曲的受拉黏结破坏现象对应；卫力固-801黏结剂黏结的LBSTP-2竖向极限承载力显著高于其他支座；LBSTP-2的极限剪应变为150%,相比STP提升了50%,且具有更强的耗能能力和复位能力。LBSTP呈现出良好的力学性能,研究成果可为废旧轮胎隔震垫在村镇隔震技术中的应用提供理论参考。 |

| Abstract: |
| To promote the application of isolation technology in low-rise village buildings, a low-cost and easy-to-produce layer-bonded scrap tire rubber pads (LBSTP) is developed. Three types of high-toughness bonding agents were selected to reinforce the scrap tire rubber pads (STP) through interlayer bonding. Bonding failure tests and mechanical performance tests were conducted to observe the failure pehomena of bonding delamination and shear. Based on the bonding failure mehcanisms, the mechcanical properties of LBSTP were analyzed. Results show that the V-SC2000 adhesive has the highest strength but the lowest ductility, while the Yuzhu adhesive has the lowest strength but the best ductility, corresponding to the tensile bonding failure phenomena observed at the corners of LBSTP during the shear test. The LBSTP-2 bonded with Weili-801 adhesive shows a significantly higher vertical ultimate bearing capacity compared to other supports. The ultimate shear strain of LBSTP-2 is 150%, which is a 50% increase over the STP, indicating improved energy dissipation and repositioning capabilities. The LBSTP exhibits excellent mechanical properties, and the research findings provide theoretical references for the application of waste tire shock absorbers in isolation technology for village buildings. |
