STRUCTURAL ENGINEERING

Structural Analysis Procedure

We believe the secret behind the optimal structural design is emanated from the close work of engineers, client, architect and all collaborators of the project.

We are carrying in our office and in-share with our partners the structural calculations, building physics analysis for thermal and the simulation of the design in 3D engineering models.

We are using a tuned up procedure with elegant output format in the structural analysis for parts, assembly of parts, Parts connections details and the interfaces to the substructure. This procedure is effectively integrated in Building Information Management (BIM) to have smoothly data transfer between all disciplines of the project.

1- Design Parameters and limits:-

• • Brief introduction to the engineering case and from which project discipline is addressed as well as what engineering approach has been used in the analysis.
• • Listing for Specifications, Standards, local codes, engineering theories and world class engineering programs used in the structural design.
• • Tabling the mechanical and physical properties for all materials and parts.
• • Boundary conditions:-

• - Defining the situation and mechanical properties of the sub structure and supporting points, E.g., the fc' for concrete.
• - Defining any tolerances and building movements, like soil settlement and column shortening and others, as well as any existed prestressing in the support points. These are even more critical in the case of tall buildings where method of construction and in service movements such as creep, inter-storey drift, floor rotation, floor-to-floor deflection and wind sensitivity directly impact on the design of the cladding system.

• Failure criteria: Checklist for the engineering limits and requirements that constrict the structural adequacy of the design

2- Loading Assessment:-

• Defining the loads that acted on the structural model and calculating their values. We have intensive consultancy expertise in the:-

• - Wind load engineering particularly for tall and irregular shape buildings
•  - Seismic loads and building damping mechanism - Bomb blast analysis and mitigation strategy
• - Thermal loads and thermal breakage system

3- Data Inputs:-

• • Showing sketches and drawings for conceptual design: this is the backbone of the analysis, since the right concept is the paramount step of the structural analysis
• • Referring to the 3D/2D architectural CAD drawings
• • Listing of sectional properties of the members
• • Distributing Tributary Loads of members and plates

4- Calculation Process:-

• • Implementing the relevant to-date engineering algorithm and equations in sequence calculation.
• • Using world class structural engineering programs to have FEA Model. The Boundary conditions are also defined in the model.

5- Outputs:-

• • Tabled results for stresses, displacements, forces, reactions....etc.
• • Figures, diagrams and CAD drawings to illustrate the result of the structural models.
• • 3D Models and 2D structural drawings to transfer the requirements details of the structural design to other project disciplines.

6- Guidelines & Conclusions:-

• • Comparison between the results value with failure criteria to approve the structural adequacy of the design.
• • Significant guidelines to increase safety factor of the structure and fostering the material protection system in the design to avert deterioration and corrosion of the building elements throughout a building’s life.
• • Brief method statement to insure the compliance of fabrication, dispatching and installation process with the structural design.
