摘要
根据4根有粘结预应力混凝土两跨连续梁的试验和分析,研究了其次弯矩和内力重分布的特点,提出了极限强度计算中的弯矩调幅和使用荷载作用下抗裂性能控制方法的建议。
In this paper, based on the experiments and analysis of four bonded prestressed concrete two - span continuous beams, the characteristics of secondary moment and internal force redistribution are investigated. The suggestions of moment ampli- tude modulation in ultimate strength computation and the control method for cracking behavior under service loading are pre- sented.
