Tension Loads in Normal-Weight Concrete
- The fasteners must not be driven until the concrete has reached the designated minimum compressive strength.
- Minimum concrete thickness must be three times the fastener embedment into the concrete.
- The allowable shear values are only for the fasteners in the concrete. Members connected to the concrete must be investigated in accordance with accepted design criteria.
