چکیده:
On the one hand, the absence of seismic rehabilitation in conservation projects and restoration of historical buildings and on the other, the territorial characteristics reveal an insufficient cognition and inexperience in conservation. Inadequate knowledge and high level of seismic rehabilitation leads to projects which will not be accepted by conservation authorities owing to massive interventions and ignoring the building value. Therefore, the seismic rehabilitation as a significant issue is obliterated during conservation process.
In other words, the effective seismic rehabilitation in conservation process of historical buildings is only possible by recognizing the current deficiencies in seismic rehabilitation procedure of historical buildings and developing its own methodology.
Using logical reasoning, this research tries to represent a theoretical basis of seismic rehabilitation in
relation to conservation principles, from the earliest to the most recent approaches, interventions, strategies and rehabilitation solutions. Therefore, this research is theoretical in nature and aims at making seismic rehabilitation of historical buildings distinct from the other ones and divides it to two reinforcement and repairing branches. Thereafter, it focuses on reinforcement branch for its coordination with preventive conservation. Moreover, it offers new definitions of seismic rehabilitation value and the intervention anti-value. The anti-value of intervention will then be recognized for all solutions and rehabilitation levels. Eventually, the intervention network based on the acknowledged rehabilitation aspects such as rehabilitation type, intervention form, rehabilitation cost, returnability limitations and technology type in all solutions is provided. At the end the required infrastructures for exterminating the current deficiencies in seismic rehabilitation of historical buildings are pointed out. Interaction and confrontation of historical conservation ideas and seismic rehabilitation knowledge in defining the strategies and solutions is the prominent feature of this research.

Inadequate knowledge and high level of seismic rehabilitation leads to projects which will not be accepted by conservation authorities owing to massive interventions and ignoring the building value.
Using logical reasoning, this research tries to represent a theoretical basis of seismic rehabilitation in relation to conservation principles, from the earliest to the most recent approaches, interventions, strategies and rehabilitation solutions.
This research question is what are the effective strategies for seismic rehabilitation of historical buildings that are each different in value and limitations?
Research methodology This study uses logical reasoning for presenting the theoretical studies on seismic rehabilitation literature combined with preservation principles and provides a theoretical base from the early measures to up-to-date approaches, intervention and strategies.
Regarding seismic actions and remedial measures for the structural conservation and restoration of cultural heritage, strategies are effectively articulated (Giorgio Croci, 2016: 380) (Tim L, 2015).
In addition, the specific methodology for seismic rehabilitation of historical buildings has been developed by linking three categories of financial costs, resistance capacity and architectural value (Meshki, 2002: 87).
The prevalent culture and the need for seismic rehabilitation of historical buildings The first deficiency is that the most extensive seismic rehabilitation programs have been implemented after massive and destructive earthquakes when the amount of public attention and awareness to the risk has had increased to the highest level.
As shown in Fig. 6, accepting the conservation and seismic rehabilitation of historical buildings by the first approach (reinforcement) significantly requires less intervention than the second approach (repair).
