Abstract
The publication presents a study aimed at bridging the gap between research findings and established design codes for evaluating crack width in one-way reinforced concrete slabs. The primary concern addressed is the cracking behavior and its subsequent impact on slab durability, particularly the corrosion of reinforcement caused by such cracks. The research emphasizes the critical issue practitioners face in managing and designing structures to control crack-induced damage. By developing a method to estimate the maximum fracture width, the study provides a formula based on the variation in steel reinforcement areas. Specifically, the study tests slabs reinforced with steel areas of maintaining a uniform slab length of 2 meters and a width of 0.6 meters. Key findings reveal that traditional research codes and prediction formulas suggest the maximum crack width is not heavily dependent on the steel area (As). However, the study's experimental data indicate that increasing the steel area effectively reduces the maximum crack width. The study concludes with the development of an approximation formula tailored for one-way slabs, offering a practical tool for engineers to manage crack widths effectively in slab construction, thus enhancing structural durability.
