Summary Base thickness design – challenging Optimum steel depth – for thicker slabs, longitudinal steel needs to be above the mid-depth; otherwise, there could be horizontal cracking and distresses. Primary cause for distresses at TCJs is poor consolidation of concrete – no need for additional steel.
