DESTRUCTIVE TESTING OF CONCRETE The existing structures are required to damage to the extent of taking out samples. The following are the tests carried out by destructive process (i) Taking cores & compression testing (ii) Petro graphic analysis (iii) Rapid soluble chloride test (iv) Tension test of reinforcing bars NONDESTRUCTIVE TESTING OF STRUCTURAL STEEL Existing steel structural elements can be tested by the following nondestructive methods to determine the condition of steel members and their connections: (i) Visual (ii) Ultrasonic testing (iii) Radiography (iv) Magnetic particle test (v) Liquid penetrate test (vi) Hardness Seismic retrofitting is the modification of existing to make them more resistant to , ground motion, or failure due to . With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Prior to the introduction of in the late 1960s for developed countries (US, Japan etc.) and late 1970s for many other parts of the world (Turkey, China etc.),[1] many structures were designed without adequate detailing and reinforcement for seismic protection. In view of the imminent problem, various research work has been carried out.
