General Notes:

Preamble:This document and related drawings explain the design philosophy for precast concrete frame structure.The frame above is designed as braced frame. Precast concrete shear walls and concrete block infillshear walls considered as bracing.

Customer Reference Information:

Drawings: Architect's drawings No. 600, 610 and 611 from 22nd of Aug. 2011 and 3D model

Engineer's drawings No. 007, 008, 009 and 011, Rev. T (Tender) from 20th of May 2011

Design Basis:1. BS 8110-1:1997 Structural use of concrete; Code of practice for design and construction2. BS 6399-1:1996 Loading for buildings; Code of practice for dead and imposed loads3. BS 6399-2:1997 Loading for buildings; Code of practice for wind loads4. BS 6399-3:1988 Loading for buildings; Code of practice for imposed roof loads

5. Responsibility of Concast Precast is limited to design, manufacture and supply of precast concrete elements only. There is no responsibility of Concast Precast for ground conditions and foundations, temporary works, erection and design associated with overall stability which may affects the stability of the structure.

Design Criteria:

Loadings:

Densities of materials to be used in the calculation of loading:

Precast Concrete = 24.00 kN/m3

In-situ Concrete = 24.00 kN/m3

Quinne lite B5 Block = 6.50 kN/m3

Standard 5N block = 21.50 kN/m3

Steelwork = 78.50 kN/m3

Note: Self weight of the above materials is calculated by SCIA structural engineering software infinite element calculation automatically. Final loading take down value depends on geometry of anyparticular structure element.

Load Case Vertical Characteristic Loading:

LC 1 Self weight; refer to the note above for details

Roof Loads:

Dead Load:

35 mm Gravel = 0.70 kN/m2

Asphalt = 0.60 kN/m2

125 mm Dp. Screed to fall = 3.00 kN/m2

225 mm Dp. or 175 mm Dp. Precast Concrete Slab including screed = 5.4/ 4.2 kN/m2 calculated by softwareInsulation and void formers = 0.20 kN/m2

LC 2 Total Roof Dead Load excluding slab self weight = 4.50 kN/m2
