无黏结预应力混凝土梁残余预应力计算

CALCULATION FOR RESIDUAL PRESTRESS OF UNBONDED PRESTRESSED CONCRETE BEAMS

通过试验结合理论分析,找出对预应力较为敏感的静力影响参数,推算出了对后张法无黏结预应力混凝土梁残余预应力计算公式。充分考虑工程实际,提出了如何对计算公式中的参数根据实际情况进行修正。为探索混凝土结构的残余预应力的准确检测与推算做出了尝试。

this paper based on the analysis of the test with,find out the static of sensitive parameters on prestrssed,calculate the post tensioned unbonded prestressed concrete beam calculation formula of residual prestress. Considering the practical engineering,the question of how the parameters in the formnla based on the actual situation of the amendment. Attempts were made to detect the residual prestress concrete structure exploration and forecast.
