A colleague asked me to post the following questions:
What ACI code criteria should one follow when designing a concrete pilaster (assume the area required for bearing is not an issue)? Two examples: 1) A steel column is supported by widening the narrow perimeter grade beams instead of widening the entire beam. and 2) the pilaster is very large (for architectural reasons, for instance) and provides support for a small, lightly loaded steel column.
What is the required amount of minimum steel required and the amount and type of ties required?
Where is the term "pilaster" defined?
Thanks in advance
