NOTES:

1. CASE 1 IS DEFINED AS BARS WITH CLEAR SPACING OF AT LEAST 2 x db AND WITH

CLEAR COVER AT LEAST db.

2. CASE 2 IS DEFINED AS BARS THAT DO NOT SATIFY THE REQUIREMENTS OF CASE 1.

3. FOR BARS CAST WITH 12" OR MORE OF FRESH CONCRETE BELOW, MULTIPLY THE

VALUES BY 1.3.

4. FOR LAP SPLICES, MULTIPLY THE VALUES BY 1.3.

5. FOR LIGHTWEIGHT CONCRETE, MULTIPY THE VALUES BY 1.34.

NOTES:

1. MINIMUM EFFECTIVE EMBEDMENT IS APPLIED TO POST INSTALLED ANCHORS UNLESS

OTHERWSE NOTED IN THE DETAIL.

2. REQUIRED SHEAR CAPACITY IS AN UNFACTORED LOAD.
