The strength of existing concrete buildings and structures can be evaluated analytically or in conjunction with a load test. The recommendations in this report indicate when such an evaluation may be needed, establish criteria for selecting the evaluation method, and indicate the data and background information necessary for an evaluation.

Methods ofFormat: Paperback. The concrete strength of each building was determined by core sampling and laboratory testing. Randomly selected components for core sampling were identified to meet with minimum requirements. Strength Evaluation of Existing Concrete Buildings Reported by ACI Committee   Strength of existing concrete buildings may be evaluated either analytically or by static load tests.

These recommendations indicate when such an evaluation may be needed, establish criteria for selecting the evaluation method, and indicate the data and conditions necessary for conducting either type of evaluation.

Chapter 20 of the Code has been extensively revised to provide more specific guidance regarding the strength evaluation of existing structures. If doubt exists that a part or all of a structure meets the safety requirements of the ACI Code, it is mandatory that a strength evaluation be carried : Edward S.

The compressive strength of masonry can be evaluated by testing masonry prisms removed from the wall or by using cores cut from a grouted portion of the wall. If vertical reinforcement is present in the wall, testing a prism can be difficult because the vertical reinforcing steel carries load.

The strength of existing concrete buildings and structures can be evaluated analytically and supplemented where necessary with load testing. The recommendations in this report indicate when such an evaluation may be needed, establish criteria for selecting the evaluation method, and indicate the data and background information necessary for an evaluation.

For the concrete structures, age related degradation can occur due to corrosion of reinforcing steel which in turn can lead to cracking and spalling of concrete.

In case there is doubt about the safety requirements of a structure, licensed design professional or building official can ask for a strength evaluation. In the start, methods simpler than the load test are considered and load test can be avoided if all involved parties are satisfied with the result of such evaluation.
