波形齿体系张拉并锚固CFRP片材的预应力损失

Experimental Analysis of Pre-stress Loss on Tensioning and Anchoring CFRP Sheet with Wave-shaped-gear

机械夹持粘结型锚具锚固的CFRP板预应力损失主要是结构弹性压缩造成，一般是张拉预应力的10%左右，锚固效率比粘结型锚具高。

The slight prestress losses of CFRP laminate with mechanical gripping bond-type anchor are mainly due to elastic deformations .

CFRP作为系杆其总预应力损失率的最大测量值为2.1%，预应力损失较小，其预应力值稳定。

The maximum measured value of CFRP tie bars prestressing loss rate is 2.1 % . The loss of prestress is smaller .

粘结型锚具锚固CFRP板预应力损失因为较大的锚固装置变形可达张拉预应力的30%-50%。

The prestress losses of CFRP laminate with bond-type anchor were 30 % - 50 % of the initial prestress because of the large deformation of anchorage set .
