In this section, we will review some of the key concepts and methods of RCC design that are covered in Reinforced Concrete Design By Oyenuga Rar --.
Load Estimation and Load Tracing
Load estimation is the process of determining the magnitude and distribution of the forces that act on a structure. Load tracing is the process of following the path of these forces from the point of application to the foundation level. These processes are essential for the safe and economic design of RCC structures.
The main types of loads that affect RCC structures are:
Dead loads: These are the permanent loads due to the self-weight of the structure and any attached or fixed elements.
Live loads: These are the variable loads due to the occupancy and use of the structure, such as people, furniture, vehicles, etc.
Wind loads: These are the dynamic loads due to the pressure and suction of the wind on the exposed surfaces of the structure.
Earthquake loads: These are the inertial loads due to the ground motion during an earthquake.
Other loads: These are the special loads that may arise from specific situations, such as temperature changes, soil pressure, water pressure, impact, blast, etc.
The load estimation and load tracing methods depend on the type and complexity of the structure. Some of the common methods are:
Simplified methods: These are approximate methods that use empirical formulas or tables to estimate the loads and their effects on simple structures or elements.
Analytical methods: These are rigorous methods that use mathematical models and equations to calculate the loads and their effects on complex structures or elements.
Numerical methods: These are computer-based methods that use software programs and algorithms to simulate the loads and their effects on any type of structure or element.
Design Philosophies and Codes
Design philosophy is the approach or method that is used to ensure that a structure is safe and serviceable under all possible loading conditions. Design code is a set of rules or standards that specify the design philosophy, criteria, methods and procedures for a particular type of structure or material.
The main design philosophies for RCC structures are:
Working stress method: This is a traditional method that assumes that the structure behaves elastically under service loads and that the stresses in concrete and steel do not exceed certain allowable values.
Limit state method: This is a modern method that considers two limit states for the structure: ultimate limit state (ULS) and serviceability limit state (SLS). ULS corresponds to the maximum load that causes failure or collapse of the structure. SLS corresponds to the normal load that causes deflection, cracking or vibration of the structure. The structure is designed to satisfy both limit states with appropriate factors of safety.
Performance-based method: This is an advanced method that evaluates the performance of the structure under different levels of loading and environmental conditions. The performance criteria include strength, stiffness, ductility, durability, etc. The structure is designed to achieve a desired level of performance with minimum cost and environmental impact.
The main design codes for RCC structures are:
National codes: These are codes that are developed and adopted by a specific country or region. They reflect the local practices, materials, climate and seismicity. Some examples are ACI 318 (USA), BS 8110 (UK), IS 456 (India), etc.
International codes: These are codes that are developed and adopted by international organizations or committees. They aim to harmonize the design rules and standards across different countries or regions. Some examples are Eurocodes (Europe), ISO 2394 (International), etc. 061ffe29dd
