Abstract:
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. Methods of determining concrete and steel properties used in the analytical investigation are described. It is recommended that theoretical analysis follow principles of ultimate strength design outlined in ACI 318-63, and that a structure be considered satisfactory if load factors and deflections satisfy requirements of ACI 318-63. Procedures for conducting static load tests are prescribed, and criteria are established for deflection and recovery of the structure beina evaluated.
