摘要:
在保证最小干预原则的前提下,对由于砂浆性能退化引起的历史建筑砌体结构安全性不足问题,提出了置换砂浆加固砌体结构的方法。以鼓浪屿历史建筑砌体结构为工程背景,模拟其结构力学性能,考虑不同灰缝厚度和单双面水泥砂浆抹面对历史建筑砌体结构性能的影响,共设计6个砌体试件,并进行了剪压复合试验。结果表明:在置换砂浆深度都是40 mm的情况下,灰缝厚度对砌体结构抗剪性能的影响十分显著,5 mm灰缝厚的试件比10 mm灰缝厚的试件承载力下降幅度为68.6%,而20 mm灰缝厚的试件比10 mm灰缝厚的试件承载力下降了8.7%; 在都未置换砂浆的情况下,单面水泥砂浆抹面的试件比未抹面的试件承载力提高了13.4%,双面水泥砂浆抹面的试件比未抹面的试件承载力提高了19.6%; 灰缝厚度和单双面水泥砂浆抹面对砌体结构的影响较为显著,在采用置换砂浆加固砌体结构时需要考虑这些影响; 试验结果可以为历史建筑砌体结构的加固提供一定的参考依据。
Abstract:
On the premise of guaranteeing the principle of minimum intervention, the method of replacing mortar to strengthen masonry structure was put forward to solve the problem of insufficient safety of masonry structure in historical buildings caused by deterioration of mortar performance. Taking the masonry structure of Gulangyu historical building as the engineering background, the existing mechanical properties of the structure were simulated, and six masonry specimens were designed considering the influence of different mortar thickness and the masonry structure strengthened with single or double-faced cement mortar on the behavior of the masonry structure in historical buildings. The shear-compression composite test was carried out. The results show that the mortar thickness has a significant effect on the shear resistance of masonry structures when the mortar replacement depth is 40 mm. The bearing capacity of specimens with 5 mm mortar thickness is 68.6% lower than that with 10 mm mortar thickness, while that with 20 mm mortar thickness is 8.7% lower than that with 10 mm mortar thickness. Without mortar replacement, the bearing capacity of specimens coated with single cement mortar is 13.4% higher than that of specimens without strengthening, and that of specimens coated with double cement mortar is 19.6% higher than that of specimens without strengthening. The mortar thickness and the strengthening with single-faced or double-faced cement mortar have significant effects on masonry structure. These effects need to be considered when using replacement mortar to strengthen masonry structure. The test results can provide some reference for the strengthening of masonry structure in historical buildings.
