Importance of structural design
- 1. WELCOME TO OUR PRESENTATION Importance of Structural Design Presented by Mir Kamrul Islam
- 2. What are Structural Design? Definition: A type of technical drawing that shows details information such as Foundation, Roof, Beams etc. Applies Math and Science concepts design structures, resulting in stability and sustainability of the structure.
- 4. 1. Architect comes out with building layout. Steps:
- 5. 2. The structural engineer fits the structure to the architecture, and decides on what structural systems to use. 3. A general layout is developed. Structural type -Selection of material -Estimation of cost
- 6. 4. The loads are investigated and calculated. 5. Stress Analysis -Maximum capacity of loads -Specifications and codes
- 7. 6. Selection of elements 8. Approval of architect. 9. Submit to authorities for approval. 7. Drawing, Detailing and Specification of Jobs
- 8. 10.Proceed to construction. 11.Amendments of construction drawings. 12.As-built drawings drawn.
- 10. Lines
- 11. Structural Deign are always to scale. 1:100 1:50 1:25 1:10 1:5 Scales Most Common Scales:
- 12. Dimensions Factors to take into consideration: method and line type that is used for dimensioning. The linear dimension would be the overall, auxiliary depiction and the second form of dimensioning would be the diameter and radi of the structure. A mixture of the two would depict the position of ‘The Hole’ in an engineering drawing.
- 14. - Shows the builder and others the required size for every parts of the building. - Unbroken lines. - 2 mm away from the object being dimensioned.
- 15. 2-Dimensional (2D) There are multiple types of 2D Drawing Types in Structural Design. - Plan: ‘Top View’, ‘Floor Plan’ & ‘Roof Plan’ - Sections: ‘Cross-Section’ & ‘Longitudinal Section’ - Elevations: ‘Front Elevation’, ‘Right Elevation’, ‘Left Elevation’ and ‘Rear Elevation’
- 16. 3-Dimensional (3D) 3-Dimensional Design drawings are also known as ‘Production Drawings’ The 3-Dimensional (3D) Drawing Types: - Orthogonal Projections - Pictorial Drawing: Isometric & Oblique - ‘’Working Drawings’’
- 18. Orthographic Projection Orthographic projection drawings are used to describe buildings, structures or objects pictorially. Showed through first and third angle projection.
- 20. Graphical Projection Graphical Projection drawings have two different types: 1) Perspective projection 2) Parallel projection
