ENGINEERING SPECIFICATIONS I PRODUCT DESCRIPTION I HIGH STRENGTH PRECAST CONCRETE LINTELS DESIGNED TO BE UNFILLED OR FILLED TO FORM A COMPOSITE REINFORCED BEAM USING CONCRETE MASONRY UNITS. I MATERIALS I . F'C 8" PRECAST LINTELS = 3500 PSI . F'C 8" PRESTRESSED, 6" AND 12" PRECAST LINTELS = 6000 PSI . F'C 4" PRECAST UNTELS = 3000 PSI . GROUT PER ASTM C476 F'G = 3000 PSI W/ MAXIMUM 3/8 INCH AGGREGATE AND 8 TO 11 INCH SLUMP. IGENERAL NOTES I 1. PROVIDE FULL MORTAR HEAD AND BED JOINTS. 2. SHORE FILLED UNTELS AS REQUIRED. 3. INSTALLATION OF LINTEL MUST COMPLY WITH ARCHITECTURAL AND/OR STRUCTURAL DRAWINGS. 4, U-UNTELS ARE MANUFACTURED WITH 5-1/2 INCH LONG NOTCHES AT ENDS TO ACCOMODATE VERTICAL CELL REINFORCING AND GROUTING. 5, ALL UNTELS MEET OR EXCEED l./360 VERTICAL DEFLECTION, EXCEPT UNTELS 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 UNTEL CAVIlY. 7. 7/32 INCH DIAMETER WIRE STIRRUPS ARE WELDED TO THE BOTTOM STEEL FOR MECHANICAL ANCHORAGE, I SAFE LOAD TABLE NOTES I 1. ALL VALUES BASED ON MINIMUM 4 INCH NOMINAL BEARING. EXCEPTION: SAFE LOADS FOR UNFILLED UNTELS MUST BE REDUCED BY 20 % IF BEARING LENGTH IS LESS THAN 5-1/2 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 CAPACIlY CAN BE OBTAINED BY THE DESIGNER BY PROVIDING ADDmONAL REINFORCED MASONRY ABOVE THE PRECAST UNTEL. SEE REINFORCED CMU ON PAGE 4. 6. ONE #7 REBAR MAY BE SUBSTITUTED FOR TWO #5 REBARS IN 8" UNTELS 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, SAFE GRAVIlY LOADS FOR 8" PRECAST & PRESTRESSED U-UNTELS (AST-(A4IT4I ______ lYPE LENGTH ~ SAFE LOAD - POUNDS PER LINEAR FOOT Bf8-0B 8fl2-0B 8F 16-oB 8F20-oB Bf24-oB 8F28-oB Bf32-0B 8U8 Bf8-1B Bf12-1B 8Fl6-1B BF2G-1B 1lF24-1B BF28-1B Bf32.1B 3069 4605 6113 7547 8974 10394 11809 2231 3069 4605 6113 7547 8974 10394 11809 3069 3719 5163 6607 8054 9502 10951 2231 3069 4605 6113 7547 8974 10394 11809 2561 2751 3820 4890 5961 7034 8107 1966 2693 4605 6113 7547 8974 10394 11809 1969 2110 2931 3753 4576 5400 6224 1599 2189 4375 6113 7547 (7 8672 10294 11809 1349 1438 1999 2560 3123 3686 4249 1217 1663 3090 5365 7547 (36 7342 (19 8733 09 10127 (19 1105 1173 1631 2090 2549 3009 3470 1062 1451 2622 4360 7168 (45 6036 (19 7181 (19 8328 (20 1238 2177 3480 3031 3707 4383 5061 908 1238 2177 3480 5381 8360 10394 (37 8825 (14 1011 1729 2632 2205 2698 3191 3685 743 1011 1729 2661 3898 5681 8467 (44 6472 (15 699 1160 1625 2564 3486 2818 3302 752 1245 1843 2564 3486 4705 (37 6390 (47 535 890 1247 2093 2777 2163 2536 643 1052 1533 2093 2781 3643 (38 4754 (45 582 945 1366 1846 2423 3127 4006 582 945 1366 1846 2423 3127 4006 540 873 1254 1684 2193 2805 3552 540 873 1254 1684 2193 2805 3552 471 755 1075 1428 1838 2316 2883 471 755 1075 1428 1838 2316 2883 424 706 1002 1326 1697 2127 2630 442 706 1002 1326 1697 2127 2630 NR NR NR NR NR NR NR 458 783 1370 1902 2245 2517 2712 NR NR NR NR NR NR NR 412 710 1250 1733 2058 2320 2513 NR NR NR NR NR NR NR 300 548 950 1326 1609 1849 2047 NR NR NR NR NR NR NR 235 420 750 1037 1282 1515 1716 NR NR NR NR NR NR NR 180 340 598 845 1114 1359 1468 NR NR NR NR NR NR NR 165 315 550 784 1047 1285 1399 NR NR NR NR NR NR NR 129 250 450 654 884 1092 1222 (#) THE NUMBERS IN PARENTHESIS ARE PERCENT REDUCTIONS FOR GR40 FIELD ADDED REBAR.
