Deflection of reinforced concrete slabs increase with time due to factors like creep of concrete, the decrease in the rigidity by cracking. Moreover, additional deflection after cracking is known to occur becouse of steel slippage at the fixed adge. In this paper, a method that can calculate long-term deflections of continuous reinforced concrete slabs is given. Steel slippage is evaluated by bond creep analysis in this method. A comparison of the experimental and calculated deflections shows that both are generally in agreement. The effects of slab thickness, slab effective depth, ratio of reinforcement and orther factors on the deflection of slabs are numerically analyzed.
