MATERIALS <br />1. <br />f'c 8" precast lintel = <br />3500 psi <br />2. <br />f'c prestressed lintel = <br />6000 psi <br />3. <br />Grout per ASTM C476 <br />f'g = 3000 <br />psi w/ maximum 3/8 <br />inch <br />aggregate & 8 to 11 <br />inch slump <br />4. <br />Concrete Masonry Units (CMU) per <br />ASTM C90 w/minimum <br />net area <br />compressive strength <br />= 1900 psi <br />5. <br />Rebar per ASTM A615 <br />grade 60 <br />6. <br />Prestressing strand per <br />ASTM A416 <br />grade 270 low relaxation <br />7. <br />Mortar per ASTM C270 <br />type M or S <br />L 11 N <br />DETAIL "B"-' <br />SAFE LOAD TABLE NOTES <br />1. All values based on minimum 4 inch <br />nominal bearing. <br />Exception: Safe loads for unfilled lintels must <br />be reduced by 20% if bearing length is <br />less than 6 1 /2 inches. <br />2. N.R. = Not Rated <br />3. Safe loads are superimposed allowable loads. <br />4. Safe loads based on grade 40 or grade 60 <br />field rebar. <br />5. One #7 rebar may be substituted for two <br />#5 rebars in 8" lintels only <br />6. The designer may evaluate concentrated <br />loads from the safe load tables by <br />calculating the maximum resisting moment <br />and shear at d-away from face of support. <br />7. For composite lintel heights not shown, <br />use safe load from next lower height shown. <br />8. For lintels lengths not shown, use safe load <br />from next longest length shown <br />9. All safe loads in units of pounds per linear <br />foot <br />10. All safe loads based on simply supported <br />span. <br />11. The number in the the parenthesis <br />indicates the percent reduction for grade 40 <br />field added rebar. <br />Example 7'-6" lintel type 8F32-1 B safe <br />gravity load = 6472_ <br />GENERAL NOTES <br />1. <br />Provide full mortar bed and head joints. <br />2. <br />Shore filled lintels as required. <br />3. <br />Installation of lintel must comply <br />with the architectural <br />and/or structural documents. <br />4. <br />U-Lintels are manufactured with <br />5 1 /2" long notches at <br />the ends to accomodate vertical <br />cell reinforcing and grouting. <br />5. <br />Reference the CAST-CRETE Load <br />Deflection Graph brochure <br />for lintel deflection information. <br />6. <br />Bottom field added rebar to be <br />located at the bottom <br />of the lintel cavity. <br />7. <br />7/32" diameter wire stirrups are <br />welded to the <br />bottom steel for mechanical anchorage. <br />8. <br />Cast -in -place concrete may be <br />provided in composite lintel <br />in lieu of concrete masonry units. <br />9. Safe load rating based on rational design analysis per <br />ACI 318 and ACI 530 <br />10. Product Approvals: Miami -Dade County, Florida Nos. <br />03-0606.05 & 03-0605.04. Florida Certificate of Product <br />Approval number FL158. <br />11. The exterior surface of lintels installed in exterior concrete <br />masonry walls shall have a coating of stucco applied in <br />accordance with ASTM C-296 or other approved coating. <br />12. Lintels loaded simultaneously with vertical (gravity or <br />uplift) and horizontal (lateral) loads should be checked <br />for the combined loading with the following equation: <br />Applied vertical load + Applied horizontal load < 1 .0 <br />Safe vertical load Safe horizontal load <br />13. Additional lateral load capacity can be <br />obtained by the designer by providing additional reinforced <br />concrete masonry above the lintel.
