Title: Increase in Crack Width in Reinforced
Concrete Beams Under Sustained Loading
Author(s): LeRoy A. Lutz, Nand K. Sharma, and Peter Gergely
Publication: Journal Proceedings
Appears on pages(s): 538-546

Abstract:Test results are presented for the increase of flexural crack widths due to sustained loading. The width of the cracks were measured for 5 months. The effects of compression reinforcement were also investigated. The widening of the cracks is explained by the increase in steel stress at sections between surface cracks due to increased internal cracking, and by the creep of concrete.
