Design of Concrete Structures for Durability
Adequate concrete durability can be obtained in the design phase when a structure is conceived, and structural calculations are made, details are designed, materials and their proportions, as well as possible additional preventative measures, are selected. Prevention is further materialized ...
Mechanism of High-Performance Concrete
High-performance concrete can be produced through the use of low w/c ratio, pozzolanic materials, packing aggregates densely, and improve transition zone strength. Superplasticizers reduce water content by dispersing cement particles and maintain the required workability. Concerning pozzolanic materials, it improves ...
Understanding Shear Forces and Bending Moments Diagrams
Shear forces and bending moments are resultants which are used to conveniently represent the internal forces that develop within a beam when external loads are acting on it.
What is Spiral Staircase?
A spiral staircase is a round stair system in which the individual steps connect to a center column, hence forming a complete circle. The diameter of the circle creates the diameter of the staircase. This article explains the general features ...
Non-Destructive Test on Structural Steel and Welds
