ENGINEERING 1 SPECIFICATIONS I PRODUCT DESCRIPTION HIGH STRENGTH PRECAST CONCRETE LINTELS DESIGNED TO BE UNFILLED OR FILLED TO FORM A COMPOSITE REINFORCED BEAM USING CONCRETE MASONRY UNITS. I MATERIALS . F'C 8" PRECAST LINTELS = 3500 PSI . F'C 8" PRESTRESSED, 6" AND 12" PRECAST LINTELS = 6000 PSI . F'C 4" PRECAST LINTELS = 3000 PSI . GROUT PER ASTM C476 F'G = 3000 PSI W/ MAXIMUM 3/8 INCH AGGREGATE AND 8 TO 11 INCH SLUMP. IGENERAL NOTES 1. PROVIDE FULL MORTAR HEAD AND BED JOINTS. 2. SHORE FILLED LINTELS AS REQUIRED. 3. INSTALLATION OF LINTEL MUST COMPLY WITH ARCHITECTURAL AND/OR STRUCTURAL DRAWINGS. 4. U-LINTELS ARE MANUFACTURED WITH 5-1/2 INCH LONG NOTCHES AT ENDS TO ACCOMODATE VERTICAL CELL REINFORCING AND GROUTING. 5. ALL LINTELS MEET OR EXCEED l../360 VERTICAL DEflECTION, EXCEPT LINTELS 17'-4" AND LONGER WITH A NOMINAL HEIGHT OF 8" MEET OR EXCEED l../180. 6. BOTTOM FIELD ADDED REBAR TO BE LOCATED AT THE BOTTOM OF LINTEL CAVITY. 7.7/32 INCH DIAMETER WIRE STIRRUPS ARE WELDED TO THE BOTTOM STEEL FOR MECHANICAL ANCHORAGE. I SAFE LOAD TABLE NOTES 1. ALL VALUES BASED ON MINIMUM 4 INCH NOMINAL BEARING. EXCEPTION: SAFE LOADS FOR UNFILLED LINTELS MUST BE REDUCED BY 20 % IF BEARING LENGTH IS LESS THAN 6-1/2 INCHES. 2. N.R. = NOT RATED. 3. SAFE LOADS ARE SUPERIMPOSED ALLOWABLE LOAD. 4. SAFE LOADS BASED ON GRADE 40 OR GRADE 60 FIELD REBAR. 5. ADDITIONAL LATERAL LOAD CAPACITY CAN BE OBTAINED BY THE DESIGNER BY PROVIDING ADDIT10NAL REINFORCED MASONRY ABOVE THE PRECAST LINTEL. SEE REINFORCED CMU ON PAGE 4. 6.0NE #7 REBAR MAY BE SUBSTITUTED FOR TWO #5 REBARS IN 8" LINTELS ONLY. 7. THE DESIGNER MAY EVALUTE CONCENTRATED LOADS FROM THE SAFE LOAD TABLES BY CALCULATING THE MAXIMUM RESISTING MOMENT AND SHEAR AT D-AWAY FROM THE FACE OF SUPPORT. . CONCRETE MASONRY UNITS (CMU) PER ASTM C90 WITH MINIMUM NET AREA COMPRESSIVE STRENGHT = 1900 PSI . REBAR PER ASTM A615 GRADE 60 . PRESTRESSING STRAND PER ASTM A416 GRADE 270 LOW RELAXATION . 7/32 INCH WIRE PER ASTM A510 . MORTAR PER ASTM C270 TYPE M OR S 8. CAST-IN-PLACE CONCRETE MAY BE PROVIDED IN COMPOSITE LINTEL IN LIEU OF CONCRETE MASONRY UNITS. 9. SAFE LOAD RATINGS BASED ON RATIONAL DESIGN ANALYSIS PER ACI 318 AND ACI 530 10. PRODUCT APPROVALS: MIAMI DADE COUNTY, FLORIDA NOS. 03-0605.05 AND 03-0605.04 l1.THE EXTERIOR SURFACE OF LINTELS INSTALLED IN EXTERIOR CONCRETE MASONRY WALLS SHALL HAVE A COATING OF STUCCO APPLIED IN ACCORDANCE WITH ASTM C926 OR OTHER APPROVED COATING. 12.LINTELS LOADED SIMULTANEOUSLY WITH VERTICAL (GRAVITY OR UPLIFT) AND HORIZONTAL (LATERAL) LOADS SHOULD BE CHECKED FOR THE COMBINED LOADING WITH THE FOLLOWING EQUATION: APPLIED VERTICAL LOAD SAFE VERTICAL LOAD + APPLIED HORIZONTAL LOAD SAFE HORIZONTAL LOAD .s,1.0 8. FOR COMPOSITE LINTEL HEIGHTS NOT SHOWN, USE SAFE LOAD FROM NEXT LOWER HEIGHT. 9. FOR LINTEL LENGTHS NOT SHOWN, USE SAFE LOAD FROM NEXT LONGEST LENGTH. 10. ALL SAFE LOADS IN UNITS OF POUNDS PER LINEAR FOOT. 11. ALL SAFE LOADS BASED ON SIMPLY SUPPORTED SPAN. 12, THE NUMBER IN THE PARENTHESIS INDICATES THE PERCENT REDUCTION FOR GRADE 40 FIELD ADDED REBAR.
