后植筋砌体的抗压性能试验研究

Experimental Study on Compression Performance of Embedded Steel Bars Reinforcement Brick Masonry

为了研究后植筋加固砌体棱柱体的受力性能,本文对6个未加固砌体棱柱体和6个采用后植筋加固的砌体棱柱体试件进行了受压试验,分析了后植筋加固砌体试件与未加固砌体试件的破坏形态、开裂荷载、极限承载力及变形能力。结果表明:后植筋砌体试件的开裂荷载、抗压强度较未加固砌体试件有所降低,但变形能力有一定程度提高。

In order to study the properties of embedded steel bars reinforcement brick masonry,on the basis of tests including the compression experiments of 6 un-strengthened brick masonry subjects and 6 adopted embedded steel bars reinforcement brick masonry,the failure pattern,the cracking resistant load,the ultimate capacity and deformation capacity of the two different groups brick masonry are analyzed.The results show that the cracking load,compressive strength of this embedded steel bars reinforcement brick masonry subject are reduced as compared to the un-strengthened brick masonry subjects,however,the deformation capacity is enhanced to a certain extent.
