Construction is perhaps the most critical stage in the life cycle of structures, mainly because of the danger of failure and the high chances of underestimating construction loads. A report developed by the American Society of Civil Engineers, based on ...

How to Calculate Load-carrying Capacity of an existing Beam for Repair?
The calculation of the load-carrying capacity of under-designed or deteriorated beams is the first step before conducting any repair or rehabilitation work. The load-carrying capacity evaluation process involves measuring the concrete member’s existing dimensions and estimating its reinforcement area and ...
How to Assess the Severity of Damage for an Existing Structure? [PDF]
The assessment of the severity of structural damage is based on several criteria such as crack width, differential settlement, and angular rotation of foundation. The extents of damages in a building can be divided into six different categories, namely, negligible, ...
Sketches/Maps of Concrete Cracks Observed in Visual Inspections
Sketches or maps or patterns of different types of cracks commonly developed in concrete structures are crucial to determine the type and cause of cracks during visual inspection. This would also reduce the time and effort needed to specify the ...
Modulus of Rupture of Concrete Beam
Modulus of rupture is a measure of the tensile strength of concrete beams or slabs. Flexural strength identifies the amount of stress and force an unreinforced concrete slab, beam or other structure can withstand such that it resists any bending failures. ...
Stability Evaluation of Gravity Concrete Structures -Dams and Retaining Walls
Stability evaluation of gravity concrete structures such as dams, retaining walls due to various reasons with methods and procedures of stability evaluation is discussed. Stability Evaluation of Gravity Concrete Structures Stability evaluation of concrete gravity structures such as dams and ...
Strength Evaluation of Concrete Structures with Physical Load Test
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 ...
