Stiffness Matrix Method

The given indeterminate structure is first made kinematic ally determinate by introducing constraints atthenodes. The required number of constraints is equal to degrees of freedom at the nodes that is…

Serviceability and Durability of Concrete

1.      How can use prevent the effect of freezing and thawing in concrete? Concrete can be restricted from frost action, damage of the structure by the entrainment of air. This entrainment…

Effects due to Corrosion on Concrete

Corrosion is defined as the process of deterioration (or destruction) and consequent loss of a solid metallic material, through an unwanted (or unintentional) chemical or electro-chemical attack by its environment,…

Classification of cracks and Cracking in Concrete

Cracking  Cracking will occur whenever the tensile strain, to which concrete is subjected, exceeds the tensile strain capacity of the concrete. The tensile strain capacity of concrete varies with age…

Concrete Design and construction errors

Misconceptions of Structural Action  Design procedures often include simplifying assumptions as to the way, in which the final structure will behave. It the designer does not ensure that the structure…
