A New Model for Crack Control in Reinforced Concrete (RC) Tank Walls (Part I and Part II)

New research is focusing on a model for calculating crack width in the case of cracks caused by progressive cooling of the wall (for example, at the stage of concrete hardening or during ambient temperature changes), the concrete shrinkage, and the...
