疲劳荷载作用下部分预应力混凝土梁钢筋应力重分布试验研究
Experimental Research on Stress Redistribution of Partially Prestressed Concrete Beam under Fatigue Loading
本文通过将钢绞线和HRB400级钢筋配制在同一高度上的混合配筋后张法有粘结部分预应力混凝土T形梁的疲劳试验，研究了疲劳荷载作用下部分预应力混凝土构件中普通钢筋和预应力钢筋之间应力分配的发展规律，并给出了一种考虑了粘结性能差异的钢筋应力增量的计算方法，计算结果和试验结果吻合较好。
In this paper,fatigue tests of post-tensioned bonded partially prestressed concrete T- beams with both prestressed strands and HRB400 ordinary reinforcement are carried out.Based on the test results,the stress and stress redistribution between prestressed and non-prestressed reinforcement in partially prestressed concrete members versus number of cycles under fatigue loading is studied,and a method considering the different bond behavior of both steel types is propoed for calculating stress increment of reinforcing steel.The calculation results fit favorably with the test results.
