Investigation of physical resilience of bazaar of Kashan against earthquake (with emphasis on the role of communication networks and open space)

Introduction: The resilience of an architectural space is the ability to deal with damages caused by an accident, which helps to return to a normal condition after the accident. One of the important aspects of resilience is the physical aspect, which means the ability of a building to withstand changes, events, and the passage of time, and the response of the building to current and future needs. One of the important aspects of resilience is the physical aspect, which means the building’s ability to withstand changes, events, and the passage of time and the response of the building to current and future needs. The seismicity of the Kashan region shows the importance of studying the issue of physical resilience in this bazaar. So, the question is, what are the resilient components of the historical Bazaar of Kashan? On the other hand, the function of the bazaar as a commercial artery of the city and the population in which it is constantly moving, and the location of the bazaar in the city center, highlights the need to address the components of open space and communication routes in this area. The next question is what is the quality of open spaces and access routes in the bazaar and how does it work from the perspective of resilience? Methodology: To investigate the components affecting Physical resilience, the research sample, has been identified and studied by descriptive, analytical, and qualitative methods. Results: In the study of physical resilience, due to the important role of open spaces and communication network in the research sample, with the help of field survey and analysis of the current situation, also, interviewing users of the historical Bazar through a questionnaire, the effective components in physical resilience were evaluated. The effect on the stability of the bazaar of Kashan and its durability and reliability were identified and determined. Conclusion: The results show that open spaces of Bazaar, due to the extent and hierarchy of access in the whole Bazaar, have a good density and distribution but in both Bazaar of Mesgarha and Darb-e-Zanjir, the length of the exit is more than standard. Evaluation of effective resilience components shows that Soltani Mosque, Mir-Panj Caravanserai, Agha Mosque, and Mir-Emad Mosque have open space with the suitable area, healthy and stable walls, are active and with direct connection with urban arteries are suitable for post-traumatic use. the way between two series of shops and Other indoor spaces such as Amin-Al-Dole Timche and other similar places as an access space face the problem of falling due to roof damage during an earthquake, improper passage ratios, and additional elements, resulting in way blockage, so This reduces the resilience of Bazaar, but the organic structure of it and the presence of load-bearing fixtures on the ceilings are positive points in creating safety in this places.
