In seismic areas many buildings need to be retrofitted.
In some cases, it is possible to apply carbon fiber-reinforcement polymer/plastic (CFRP), steel-jackets, and concrete jackets as rehabilitation methods.
Several researches have been developed with this technology in the last years.
In addition, there are guides for the design of retrofitted systems of existing structures.
However, it is necessary to count with reliable methodologies for structural analysis of these structures retrofitted.
In some cases, the codes require non-linear analysis for the verification of design proposed as retrofit.
In this study, an attempt has been done for investigating the seismic behavior of a typical existing building in Cairo by performing static pushover analysis before and after retrofitting the columns by either, reinforced concrete, steel sections or carbon fiber reinforced polymer (CFRP) composite jackets.
The selected model building represents nearly all typical construction deficiencies of buildings constructed before recent earthquake resistant design codes.
To investigate the possibility and effectiveness of the use of these systems, a comparative study was performed.
A comparison was made between a typical framed RC building and the same building after retrofitting with CFRP confinement, steel elements and concrete jackets.
By using nonlinear static (pushover) analysis, the performance levels of structural members were evaluated for all structures.
According to the results of the structural analysis, significantly larger lateral displacement and slightly higher lateral strength with respect to original performance are possible by jacketing the columns of the building with CFRP sheets.
On the other hand, a moderate larger lateral displacement and higher lateral strength by using steel-jackets was seen.
In the case of reinforced concrete jacketing, the lateral strength and stiffness were significantly increased, as well as a remarkable improvement of the lateral displacement capacity.-
