【摘要】 在现场原位检测和试验室试样破坏试验的基础上,尝试采用相同的加载设备,通过现场轴压试验测定既有历史建筑砌体材料的抗压强度及其应力-应变关系,通过现场斜压试验推算墙体的抗剪强度。与试验室结果相比表明,现场原位轴压和斜压试验是测定砌体材料强度并为数值分析提供计算依据的有效方法。由于石灰砂浆强度偏低,再加上缺乏专用的测强曲线,采用回弹法检测粘土砖抗压强度等级和贯入法检测砂浆强度的方法仍需进一步研究验证。更多还原

【Abstract】 Based on in-situ and laboratory tests,a same test equipment was used to determine the compressive strength,shear strength and stress-strain curves of brick masonry materials theoretical.Axial compressive test and diagonal compressive test in-situ are two effective methods to masonry material properties,which can be used for further analysis.By comparison analysis,it was found that effectiveness of rebound and penetration method,which are usually used to determine clay brick strength and mortar strength need to be verified due to the low strength lime mortar in historical buildings.更多还原
