ACI 562M-13: Code Requirements for Evaluation, Repair, and by ACI


This code offers ideas for a initial overview that determines the "design foundation code" that's, if the construction will be repaired in response to the ACI 318 model utilized in the unique layout, or if the fix must agree to the present ACI 318. The code offers principles for settling on power of in-situ fabric, appearing structural research, designing upkeep for power and sturdiness, requisites for balance and shoring of building, and inspection and trying out of maintenance. statement presents program assistance in addition to references for more information.

Example text

The effects of adding new members on the global stiffness and force distribution should be considered. 1 The design of the repair system shall consider the structural interaction between the existing structure and new members. The effect of the new members on the existing structure shall be evaluated according to the design basis code. 1C The design of the repair system should consider connections of new members to the existing structure. Connections of new members should be designed to transfer design forces between new members and the existing structure.

Repaired structure. An example of partial composite behavior are beams that contain shear studs to develop nominal strength, yet lack bond between the overlay and substrate. In this situation, the overlay and substrate do not maintain strain compatibility. 1 The interaction of structural members and nonstructural components that affect the response of the structure to seismic motions shall be considered in the analysis. 2 Existing, repaired, and added supplementary members assumed not to be a part of the seismic-forceresisting system shall be permitted provided their effect on the response of the system is considered and accommodated in the repair design.

3 The method of analysis shall consider the structural configuration and material properties after repair. 3C Procedures for seismic rehabilitation of concrete buildings, including analysis, are provided in ASCE/SEI 41 and supplemented in ACI 369R. These references provide details for forces, rehabilitation methods, analysis and modeling procedures, and seismic rehabilitation design. 1C The licensed design professional may lack information required to determine the strength of deteriorated or repaired structural members.
