What is the difference between working stress approach and limit state approach?

For working stress approach, service loads are used in the whole design and the strength of material is not utilized in the full extent. In this method of design, stresses acting on structural members are calculated based on elastic method and they are designed not to exceed certain allowable values. In fact, the whole structure … Read more

What is Shear Force Diagram and Bending Moment Diagram

The algebraic sum of the vertical forces at any section of a beam to the right or left of the section is known as shear force. It is briefly written as S.F.  The algebraic sum of the moments of all the forces acting to the right or left of the section is known as bending … Read more

10+ Field Tips for Inspection of Rebars or Reinforcement

In construction of a mega project there is always insightful sort of technicalities involved which has to be checked / identified technically. The process demands a sound technical engineering judgment and careful observation. Reinforced Cement Concrete, despite of other important checks, needs to be checked for rebar against the provided construction drawings / shop drawings … Read more

Download Structural Dynamics theory and Computation PDF

The analysis and design of structures to resist the effect produced by time dependent forces or motions requires conceptual idealizations and simplifying assumptions through which the physical system is represented by an idealized system known as the analytical or mathematical model. These idealizations or simplifying assumptions may be classified in the following groups;Material assumptionsLoading assumptionsGeometric … Read more

What is Wobble Coefficient in post tensioning system?

Post tensioning structures are used in the design of buildings, bridges, and other structures with great tensile strength. There are several different types of materials used to make these structures, including steel cables and bars, high-strength steels, concrete, or fiberglass with or without steel fibers. When the material is put under tension during construction (or … Read more
