摘要:
通过对2根先张折线形配筋部分预应力混凝土梁与1根后张有黏结部分预应力混凝土梁的疲劳试验,进行了疲劳荷载作用下平截面假定的验证,分析了其挠度随着疲劳循环次数增加的变化规律,探讨了部分预应力混凝土梁在疲劳荷载作用下挠度的计算方法和计算公式.结果表明,按本文提出的公式计算的结果与试验结果符合较好.
Abstract:
Through the fatigue test of two prestressed concrete beams with pretensioned linear reinforcement and one prestressed concrete beam with bonded part after tension, the flat-section assumption under fatigue load is verified, the variation law of deflection with the increase of fatigue cycle times is analyzed, and the calculation method and calculation formula of deflection of some prestressed concrete beams under fatigue load are discussed. The results show that the results calculated according to the formula proposed in this paper are in good agreement with the experimental results.
