How can you choose the best structural system for a building?

2 Architectural design

The architectural design is the aesthetic and functional vision of the building. It includes the shape, size, layout, appearance, and orientation of the building. The architectural design influences the type, configuration, and arrangement of the structural elements. For example, if the building has a complex geometry, you may need a structural system that can accommodate irregular shapes and spans. If the building has a large open space, you may need a structural system that can provide adequate stiffness and strength without obstructing the views. You should collaborate with the architect and the client to ensure that the structural system meets the design objectives and expectations.

3 Functional requirements

The functional requirements are the operational and performance needs of the building. They include the occupancy, the use, the serviceability, and the safety of the building. The functional requirements determine the load capacity, the flexibility, the durability, and the reliability of the structural system. For example, if the building is used for industrial purposes, you may need a structural system that can support heavy loads and resist corrosion. If the building is used for residential purposes, you may need a structural system that can provide thermal comfort and sound insulation. You should define the functional requirements clearly and specify the appropriate design standards and codes for the structural system.

4 Material availability

The material availability is the supply and demand of the construction materials in the market. It includes the cost, quality, quantity, and delivery time of the materials. The material availability influences the selection, specification, and procurement of the structural elements. For example, if the material is scarce or expensive, you may need a structural system that can optimize the material usage and reduce the waste. If the material is abundant or cheap, you may need a structural system that can take advantage of the material properties and performance. You should research the material availability and compare the advantages and disadvantages of different materials for the structural system.

5 Construction methods

The construction methods are the techniques and processes of building the structural system. They include the fabrication, transportation, erection, and installation of the structural elements. The construction methods affect the speed, quality, and efficiency of the project execution. For example, if the construction method is prefabricated, you may need a structural system that can be easily assembled and connected on site. If the construction method is in situ, you may need a structural system that can be easily formed and cured on site. You should evaluate the construction methods and select the most suitable one for the structural system.

6 Environmental impact

The environmental impact is the effect of the structural system on the natural and social environment. It includes the energy consumption, the carbon footprint, the waste generation, and the life cycle assessment of the structural system. The environmental impact reflects the sustainability and responsibility of the project. For example, if the environmental impact is high, you may need a structural system that can reduce the energy demand and the greenhouse gas emissions. If the environmental impact is low, you may need a structural system that can enhance the natural ventilation and the daylighting. You should assess the environmental impact and choose a structural system that can minimize the negative effects and maximize the positive effects.
