摘要
智能材料结构是土木工程领域的一个研究热点。采用碳黑砂浆试块作为混凝土的传感元件,纳米复合环氧树脂涂层作为钢筋的传感元件,通过两组机敏梁试验的开展,研究了机敏梁的压阻效应。试验结果表明,在梁的纯弯段,传感元件的压阻效应明显,且在梁的弯剪段,压阻效应也同样存在。
Smart material structure is one of the hotspots in civil engineering field .The carbon black cement mortar was used as sensing element of concrete and nano-composite resin was used as sensing element of steel .With the study of two sets of smart beam experiments , the piezoresistive effect was researched .The results proved that the piezoresistive effect of sensing element was obvious in the beam under pure bending regions .It also proved that there existed the piezoresistive effect in shear moment regions of beams .
