Structural Cracks and Classifications

structural cracks

Structural Cracks and Classifications A crack in a structural member introduces local flexibility that would affect vibration response of the structure. This property  may be used to detect existence of a crack together its location and depth in the structural member. The presence of a crack in a structural member alters the local compliance that … Read more

Vibration Analysis of Structures

model hammer

courtesy:Govardhana Rao Introduction to Vibration Analysis of Structures Civil engineering structures are always designed to carry their own dead weight, superimposed loads and environmental loads such as wind or waves. These loads are usually treated as maximum loads not varying with time and hence as static loads. In some cases, the applied load involves not … Read more

The Dynamic Analysis Of Structures

Dynamic analysis

Dynamic Analysis Of Structures Introduction to Dynamic Analysis Of Structures All real physical structures, when subjected to loads or displacements, behave dynamically.  The additional inertia forces, from Newton’s second law, are equal to the mass times the acceleration.  If the loads or displacements are applied very slowly then the inertia forces can be neglected and … Read more

Structural Dynamics and Degree of Freedom

SDOF

Structural dynamics and earthquake engineering 1. Define the concept of dynamic degree of freedom. Give some examples of single degree of freedom systems and multi degree of freedom systems. Answer: Dynamic degrees of freedom are a set of independent displacements/rotations that completely define the displaced position of the mass with respect to its initial position. … Read more
