Engineering apply and analysis of reinforced wall with geogrid by pre-tension;

Failure modes of reinforced concrete beams strengthened by pre-tensioned carbon fiber composite sheets were totally summarized and analyzed,and it was suggested that the over-reinforced concrete beams should be avoided in strengthening design.

Based on the results of experiments,the serviceability of reinforced concrete beams strengthened by pre-tensioned carbon fiber composite plastic sheets was summarized.

Research on one kind of long sensing gauge fiber Bragg grating sensor with pretension

The advantges and disadvantages between continuous and intermittence pretension are compared.

The raw materials and the pretension method are improved.
