- Abstract:
- To pre-stressed concrete beams,it is very important to forecast long-term deflection accurately tofigure out numerical relationship between creep coefficient and creep deflection coefficient.By analyzing creepdeformation of pre-stressed concrete beams under long-term loaded in ANSYS software,and studying numericalrelationship between creep coefficient and creep deflection coefficient while creep coefficient also PPR ofbeams are different,or beam creep coefficient is same but different PPR.Then the results show that full-pres-tressed conerete beams creep deflection coefficient is greater than creep coefficient,while the opposite is truefor partial-prestressed beams. Moreover,this conclusion was further proven by analytical method to creepstrain geometry model. This result may be useful for establishing accurate long-term deflection calculationmodel of pre-stressed concrete beams.
