It was found that the creep factor and the suggested deflection limits given in Eurocode 5 might not be appropriate to achieve the expected target reliabilities. To obtain a more consistent reliability, more suitable values for the mentioned parameters were suggested. However, the primary aim was ...
Ian Gilbert says “The use of the deflection multiplier kcs to calculate time-dependent deflections is simple and convenient and, provided the section is initially cracked under short term loads, it sometimes provides a ‘ball-park’ estimate of final deflection. However, to calculate the shrinkage...

The calculation result based on the structure deflection is 7% less than the observed value. The mid-span pre-stress loss is often accompanied by the "tension" of the side one, and this "tension" phenomenon is beneficial for long-term deflection control. 展开 ...
