摘要:
进行了42个(14组)玻璃纤维(GFRP)片材全长包裹砖砌体柱和9个(3组)对比砖柱的轴压试验,探讨了GFRP片材黏贴层数、试件截面尺寸、砂浆强度及倒角半径等参数对加固效果的影响; 在考虑截面有效约束区和非有效约束区的基础上,重点分析了截面尺寸对加固效果的影响。试验结果表明:由于GFRP片材的约束作用,延缓了砖柱初始裂缝的出现,加固后试件的极限强度与黏贴层数呈线性关系,采用GFRP片材包裹加固砖柱能明显提高轴压极限强度与峰值应变。
Abstract:
Forty-two(fourteen groups)brick masonry columns whole along wrapped by glass fiber reinforced plastic(GFRP)sheets and nine(three groups)brick masonry columns for comparison were tested under axial compression. The influences which were considered to affect the confinement of brick masonry columns were as follows:stick layers of GFRP sheets, sectional size of specimens, strength of mortar,and radius at the corners etc. By considering the effective controlling area and the ineffective controlling area in the column section, author intensively analyzed the influence of sectional size to reinforced result. The experiment results indicate that because of the confined effect of GFRP sheets, the appearance of initial crack is postponed; the ultimate strength of reinforced testing column and stick layers are in linear relation; GFRP sheets can obviously enhance the ultimate axial compression strength and the peak value of brick masonry columns.
