Though not a Non Destructive Test,IS – 456 – 2000 recommends Load testing of flexural members to be carried out In case the core test results do not satisfy the requirements. Many a times Load test is carried out on building & Bridge components when –
- The strength of concrete is below the acceptable norms
- Structural Design data is not available.
- Load carrying capacity of the flexural member needs to be assessed
- The members is to be subjected to a higher loads
- The members are noticed to have cracks, deflections
- The structure is damaged due to fire, earthquake, blast, corrosion etc.
- Change in use of structure
The Load Test for Building is carried out as per IS – 456.
For Bridges Load test is carried out in accordance with IRC – SP – 51 – 1999, the load test can be performed by either loading with simulation of specific IRC vehicle ( IRC – 37 ) or by other type of static load which produces the design forces.
