| 摘 要： | 为研究碳纤维布(CFRP)加固砌体结构的地震反应,选取2条天然波和l条人工波,对1/4缩尺比例的两层两开间带构造柱的CFRP加固砌体结构模型进行了模拟地震振动台试验.结果表明,随着模拟地震激励的增加,试验模型砂浆开裂并延伸,此时CFRP能有效地约束裂缝的进一步扩展；试验模型第二层动力放大系数约为第一层的2倍；当输入至峰值加速度1.40g时,试验模型层间位移角最大值为1/42,且两侧水平位移不一致,存在较为明显的扭转,但模型没有发生严重破坏.CFRP加固砌体结构具有良好的抗震承载能力和变形能力.

| Abstract: | To study the seismic performance of masonry structures retrofitted with CFRP lam inates,shaking table tests a 1/4 scaled two-story and two-bay masonry structu re involving constructional columns which was strengthened by CFRP laminates wer e carried out under the excitations of two natural earthquake records and anothe r artificial one.The results show that cracks were observed firstly in the mort ar between bricks of the test model and extended gradually with the increase of the seismic input;however,the C... |
