Objectives
of the Design of Reinforced concrete structures
1. Structural Safety: The primary objective is to ensure the safety of the structure
and its occupants throughout its intended lifespan. This involves designing the
structure to resist various loads, including gravity loads (such as the weight
of the building and its contents), as well as lateral loads (such as wind and
seismic forces), without experiencing failure or collapse.
2. Serviceability: Designing for serviceability involves ensuring that the
structure performs adequately under normal service conditions, without
excessive deflections, vibrations, or cracking that could affect its
functionality, comfort, or aesthetics. This includes considering factors such
as occupant comfort, durability, and maintenance requirements.
3.
Strength and Stability: The design aims to provide sufficient
strength and stability to resist the applied loads while maintaining structural
integrity and preventing progressive collapse. This involves selecting
appropriate materials, dimensions, and reinforcement detailing to ensure that
the structure can safely carry anticipated loads and withstand extreme events.
4.
Durability: Reinforced concrete structures are exposed to various
environmental factors, such as moisture, temperature variations, chemical
attacks, and abrasion. The design aims to enhance the durability of the
structure by specifying appropriate concrete mixes, cover thicknesses,
corrosion protection measures, and detailing to mitigate potential degradation
mechanisms and ensure long-term performance.
5.
Economic Efficiency: Designing for economic efficiency involves optimizing the use
of materials and construction methods to minimize costs while meeting
performance requirements and regulatory standards. This includes considering
factors such as material selection, construction techniques, lifecycle costs,
and constructability to achieve a balance between initial investment and
long-term benefits.
6.
Sustainability: Designing reinforced concrete structures with sustainability in
mind involves minimizing environmental impacts, conserving resources, and promoting
resilience to climate change. This may include incorporating sustainable
materials, energy-efficient design strategies, and innovative construction
techniques to reduce carbon emissions, energy consumption, and waste generation
over the lifecycle of the structure.
7. Code Compliance: The design must comply with relevant building codes, standards,
and regulations that govern the design, construction, and maintenance of
reinforced concrete structures. This ensures that the structure meets minimum
safety, performance, and quality requirements set forth by regulatory
authorities and industry organizations.
By addressing these objectives in the design process, engineers
can create reinforced concrete structures that are safe, durable, efficient,
and sustainable, meeting the needs of society while minimizing risks to the
environment and public safety.
