高性能复合砂浆钢筋网加固多孔砖砌体的抗压试验
Experiment on Fired Perforated Brick Masonry Strengthened with High-performance Ferrocement Laminate
摘要
Abstract
In view of the situation that rural dwellings have widely adopted perforated brick masonry,a method,which used high-performance ferrocement laminate(HPFL) to strengthen perforated brick masonry,was studied.In order to investigate the capacity mechanism,failure mode and bearing capacity elevated degree of perforated brick masonry strengthened by HPFL,three reference specimens and five strengthened specimens were made for the axial compression tests,with the consideration of the strength of masonry mortar and spacing of vertical and horizontal rebars.The experiment results showed that HPFL can be able to cooperate with original masonry,the ultimate capacity is greatly improved by 147.9%~289.67% and the ductility and brittle nature of the masonry are obviously improved.By comparing the experiment results and based on theoretical analysis and the experiment data fitting,a calculation method was proposed for predicting the ultimate strength of perforated brick masonry strengthened by HPFL,which could be reference for the strengthening engineering design.关键词
