The objective of design should be the achievement of an acceptable
probability that the structure will perform satisfactorily for the intended purpose during the design life.
With the appropriate degree of safety, the structure should sustain all the loads and deformations during construction and its designed life and also have adequate resistance to accidental loads and fire.
The designer should specify a grade and type of concrete that is
suitable for the environment, keep the structural layout and structural details simple and use the maximum possible repetition of member sections and connection details.
Roles and Responsibilities of Designers
The designer has to take several factors into consideration while
designing the structure as follows:
- Material to be used
- Arrangement of structural system (eg. gravitational and lateral load resisting system)
- Method of fabrication (cast in situ or prefabricated) and erection
- Installation of services (lift, water supply, power, ventilation, heating and cooling, etc.).
- Safety, economy, and aesthetics
- Required fire protection
- Operating/Maintenance and life cycle costs
