【摘要】 砌体结构灰缝强度低是其抗震性能差的主要原因。现行的砌体加固方法对砌体建筑的使用面积和外表都有不同程度的影响。注浆加固砌体结构旨在通过提高砌体结构的砂浆性能来提高砌体结构的整体性和强度,开辟了砌体加固的新路径,试验结果表明,这种方法能够使得抗压强度提高25%、抗剪强度提高209%,而且该加固方法不改变建筑外貌,尤其适合加固历史风貌建筑。更多还原

【Abstract】 The major reason for low seismic capacity of the existed masonry structures is low strength mortar.Present strengthening methods have negative effect on the housing area and appearance.In order to strengthen the seismic capacity of the existed masonry structures,a new method by grouting is proposed. The result of grouted masonry specimens shows that the compressive strength was increased by 25%,while the shear strength was increased by 209%.This meth- od is suitable for strengthening historic buildings and prevents changing the building appearance.更多还原
