Title: 437R-03: Strength Evaluation of Existing Concrete Buildings
Author(s): ACI Committee 437
Publication: Technical Documents
Appears on pages(s): 28
Keywords: cracking; deflection; deformation; deterioration; gravity load; load; load test; reinforced concrete; strength; strength evaluation; test.
Abstract: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 of determining material properties used in the analytical and load tests investigation are described in detail. Analytical investigations should follow the principles of strength design outlined in ACI 318. Working stress analysis can supplement the analytical investigations by relating the actual state of stress in structural components to the observed conditions. Procedures for conducting static load tests and criteria indicated for deflection under load and recovery are recommended.
