ABSTRACT
When selecting the concrete configuration and reinforcement layout for a concrete building, the engineer typically considers strength requirements and then addresses serviceability concerns. During the serviceability check, attention is directed to deflection and durability, but many times detailing for serviceability to mitigate cracking is overlooked. Cracking in reinforced concrete buildings can be addressed early in the design process through judicious consideration of building layout, selection of appropriate connections, and use of appropriate reinforcement detailing. It is advisable to evaluate during the member design stage those members within a structure that may be subject to various types of cracks. Predicting possible crack behavior or crack development among members within a building typically allows application of appropriate mitigating detailing. Whether cracking is caused by restrained shortening of concrete or cross-sectional action, effective detailing of concrete members can significantly impact the longterm performance and durability of the concrete structure.
