The four essential features of a successful repair are: 1. Expediency: The longer the repair is left, the more work has to be done, and the less likely that the repair will blend in. 2. Cleanliness: when repairing concrete, care must be taken to remove any dirt or dust that will prevent the repair concrete(…)
Structual Inspection
Inspection of Concrete Structures- II
Ultrasonic Testing (Pulse Velocity Test) An ultrasonic test measures the velocity of an ultrasonic pulse through a concrete member or sample. Listed below are the reasons for using ultrasonic testing: Assess the uniformity and relative quality of the concrete. Indicate the presence of cracks and voids. · Estimate the depth of a well formed crack(…)
INSPECTION OF CONCRETE STRUCTURES -I
Inspection of concrete structures in necessary to assess the building of damages, its strength, rehabilitation strategies, repair methods etc. to keep the structure safe.
STRENGTH EVALUATION OF CONCRETE BUILDINGS
Physical load test is required to determine the serviceability of the structure. Load arrangements, load intensity, loading criteria, instrumentation are explained.
STRUCTURAL EVALUATION PROCESS
STRUCTURAL EVALUATION PROCESS This procedure is applicable for conventionally reinforced cast-in-place concrete, precast-prestressed concrete and post-tensioned cast-in-place concrete. The evaluation of an existing concrete building is usually performed for stability, strength, safety and future expected life. Evaluation of a structure may be required in the following situations: Structures are subjected to excess or improper loading,(…)
FATIGUE STRENGTH OF RIVETED AND CORRODED STRUCTURES
The fatigue strength of riveted members is relatively insensitive to the rivet pattern or type of detail (cover plate details, longitudinal splice plates, and angles or shear-splice details). A major advantage of riveted (or bolted) members is that they are internally redundant. Cracking that propagates from a rivet hole is the typical phenomenon of fatigue(…)
