摘要
通过分析影响无粘结部分预应力混凝土梁极限状态性能的主要因素， 采用已收集到的１０６根梁的试验数据，并充分考虑各参数的不定性，对无粘 结部分预应力混凝土梁的极限强度进行了可靠度分析，给出了计算无粘结 筋极限应力增量与梁的极限强度设计建议公式．
Main factors affecting the behaviors of unbonded partially prestressed concrete beams under ultimate load have been analyzed. By using the experimental data of 106 unbonded PPC beams and fully considering the uncertainty of all variables, the reliability of ultimate strength of unbonded PPC beams has been analyzed to suggest calculating formulas for ultimate increasement in stress in unbonded tendons and ultimate strength for the purpose of design.
