(mm) MINIMUM TEMPERATURE BARS
ALL WALLS SHALL BE REINFORCED ACCORDING TO THE FOLLOWING SCHEDULE OF WALL REINFORCEMENT UNLESS OTHERWISE NOTED ON PLANS FIGURE 5
B. LENGTH OF BAR CUT-OFFS AND BAR CLEARANCES SHALL BE AS SPECIFIED IN
FIGURE 5. FIGURE 8
C. IF BEAM REINFORCING BARS ENDS IN A WALL THE CLEAR DISTANCE FROM THE
BAR TO THE FURTHER FACE OF THE WALL SHALL NOT BE LESS THEN 5 BAR
DIAMETER. THE REINFORCING BAR SHALL TERMINATE ON A STANDARD 90° HOOK,
MINIMUM EMBEDMENT SHALL BE 40 BAR DIAMETER FOR COMPRESSION BARS.
NOTES ON COLUMNS
A. CONFINEMENT TIES SHALL BE PROVIDED ON THE COLUMNS AT BEAM COLUMN INTERSECTION AS SHOWN IN THE FIGURE 9 AND 10 UNLESS OTHERWISE
SHOWN IN STRUCTURAL PLANS.
FIGURE 6
B. COLUMN TIES AND SPIRAL SHALL BE PROTECTED EVERYWHERE BY COVERING OF CONCRETE CAST MONOLITHICALLY WITH CORE OF MINIMUM THICKNESS OF
38mm AND NOT LESS THAN 1 1
2 TIMES THE SIZE OF THE COARSE AGGREGATE.
C. WHERE COLUMN CHANGES SIZE, VERTICAL REINFORCEMENT SHALL BE OFFSET OF A SLOPE OF NOT MORE THAN 1
D. IF THERE ARE TWO OR MORE LAYER OF REINFORCING BARS AT 900mm O.C. ]IN NO CASE SHALL BE THERE BE LESS THAN TWO SEPARATORS BETWEEN LAYER OR BARS. 5 WITH EXTRA TIES AT 100mm O.C. SHALL BE
PROVIDED THROUGHOUT THE OFFSET REGION.
E. MINIMUM CONCRETE PROTECTION OF REINFORCING BARS SHALL BE AS SHOWN IN FIGURE 6.
F. WHEN BEAM CROSSES A GIRDER, REST BEAM BARS ON TOP OF THE GIRDERS. AT COLUMN INTERSECTION, GIRDER BARS SHALL BE ON TOP OF BARS.
REINFORCING BARS SHALL HAVE 40mm MINIMUM CLEAR DISTANCE FROM WALL FACE EXCEPT FOR WALLS IN CONTACT
WITH THE GROUND WHERE A MINIMUM OF 70mm SHALL BE PROVIDED. G. GENERALLY, NO SPLICE SHALL BE PERMITTED IN BEAMS A POINT WHERE CRITICAL BENDING STRESS OCCUR, SPLICE WHERE SO PERMITTED SHALL BE SIXTY (60) BAR
DIAMETER FOR PLAIN BARS AND FORTY (40) BAR DIAMETER FOR DEFORMED BARS. NOT MORE THAN BARS AT ANY SECTION SHALL BE THEREIN. Y = 81 STOREY HEIGHT
B. CARRY VERTICAL BARS AT LEAST 800mm ABOVE FLOOR LEVEL TO PROVIDE FOR SPLICES. ELSEWHERE STOP AT CR MAXIMUM COLUMN
50mm BELOW THE TOP OF THE SLAB OR SOLID BOND WHERE THE WALL ENDS. HORIZONTAL AND VERTICAL BARS DIMENSION WHENEVER
SHALL BE SPLICED BY LAPPING A DISTANCE EQUAL TO 40 BAR DIAMETER AND WIRED SECURELY WITH NO. 16 G.I.WIRE IS GREATER
PROVIDED AT LEAST 1530mm ON CENTER.
SCHEDULE OF CONCRETE HOLLOW BLOCKS REINFORCEMENT
FIGURE 1 FIGURE 2
C. UNLESS OTHERWISE NOTED IN THE PLAN, ALL OPENING WALL 250mm THK. OR THICKNESS SHALL BE REINFORCED AROUND WITH 2 (TWO) - 20mm Ø
BARS. FOR 230mm THICK WALL AND BELOW, USE 2-16mm Ø, FOR 130mm 10mm THICK WALL, USE 2-12mm Ø BARS.
ALL WALL OPENING SHALL HAVE VERTICAL REINFORCEMENT BENT TO U-FORM LIKE STIRRUPS AND SPACED ACCORDING TO SCHEDULE (TABLE 1).
ALL CONCRETE WORKS SHALL BE REINFORCED WITH BARS OF AREA AT LEAST EQUAL TO THAT SPECIFIED IN THE LATEST EDITION OF ACI CODE.
NOTES ON REINFORCED CONCRETE SLABS GENERAL NOTES
A.IN THE INTERPRETATIONS OF THESE DRAWINGS, INDICATED DIMENSION SHALL GOVERN AND DISTANCES OF SIZES SHALL NOT BE SCALED FOR CONSTRUCTION
A. ALL SHALL REINFORCEMENT SHALL BE 18mm CLEAR FROM BOTTOM / TOP OF SLAB. PURPOSES.
B. BARS ON REINFORCED CONCRETE EXPOSED TO WEATHER SHALL PREFERABLY BE PROTECTED WITH AT LEAST 40mm AND IN NO CASE NOT LESS THAN 25mm. THIS
B. LENGTH OF CUT-OFFS SHALL BE AS SPECIFIED IN FIGURE 7.
PROVIDED MAY BE WAIVED WHEN ADEQUATE WATERPROOFING IS PROVIDED.
C. IF SLAB ARE REINFORCED ON BOTH WAYS, BARS ALONG THE SHORT SPAN SHALL BE PLACED BELOW THOSE ALONG THE LONG SPAN AT THE CENTER AND OVER THE
C. ALL CONCRETE WORKS SHALL BE DONE IN ACCORDANCE WITH THE ACI CODE FOR REINFORCED CONCRETE AND ALL STRUCTURAL STEEL WORKS IN ACCORDANCE
LONGER SPAN BARS NEAR THE SUPPORT.
WITH THE AISC SPECIFICATIONS IN SO FAR AS THEY WILL NOT CONFLICT WITH LOCAL BUILDING CODE AND THIS NOTES.
D. TEMPERATURE BARS FOR SLAB SHALL BE GENERALLY PLACED NEAR THE FACE IN TENSION. SEE TABLE 3 FOR SPACING.
D. FOOTINGS ARE DESIGNED AN ALLOWABLE SOIL BEARING CAPACITY OF 110 Kpa AT FOUNDING DEPTH OF 1.50m FROM NATURAL GRADE LINE. THE CONTRACTOR
SHALL REPORT TO THE ENGINEER IN WRITING ACTUAL SOIL CONDITIONS UNCOVERED AND CONFIRMED ACTUAL BEARING CAPACITY OF SOIL BEFORE DEPOSITING
E. UNLESS OTHERWISE NOTED IN PLANS OR SPECIFICATIONS, CAMBER ALL R.C. SLAB ALONG THE SHORTER SPAN, 3mm PER METER SPAN.
CONCRETE AND VERIFIED PRIOR TO CONSTRUCTION.
F. UNLESS OTHERWISE NOTED, ALL SLABS ON GRADE ARE TO BE REINFORCED WITH 10mm BARS AT 400mm O.C. EACH WAY AT CENTER OF SLAB CONSTRUCTION
E. NO FOOTING SHALL REST ON FILL.
