Tolerances for Concrete Foundation Construction as per ACI 117M-10
Specification tolerances for concrete foundation construction as per ACI 117M such as tolerances for plumb line deviation, location displacement, deviation from elevation, plane and cross-sectional dimensions of foundations are discussed. Fig.1: Concrete Foundation Construction Tolerances for Concrete Foundation Construction as ...
12 Types of Loads Considered for Design of Bridge Structures
Various types of loads are considered for design of bridge structures. These loads and their combinations decides the safety of the bridge construction during its use under all circumstances. The design loads should be considered properly for perfect design of ...
Assumptions in Strength Calculation of Building Materials with Explanations
Strength, resistance against failure is the important property of any civil engineering material. Every material is to be tested for its strength before going to use it. There are various external forces which acts on materials in different ways. To ...
Measures to Increase Ductility of Reinforced Concrete Structural Members
Ductility is the ability of reinforced concrete members to undergo considerable deflection prior to failure. This characteristic of reinforced concrete structural members is crucial as it provides signs of failure and prevents total collapse. This is especially significant in seismic ...
How to Mitigate Human Induced Vibrations in Reinforced Concrete Structures?
Human induced vibration may create serious serviceability problems in reinforced concrete structures. There are several modern strategic projects that have suffered from such problem for instance Millennium Bridge in London-UK. The bridge suffered from lateral synchronous excitation. The bridge had ...
What are the Thickness Requirements of Strip Foundations?
There are number of factors that control a thickness of strip foundation such as losing condition, types of soil, and depth of foundation. The thickness requirements of strip foundation according to load conditions and depth of foundation are discussed. Fig.1: ...
