Development of static analysis and relations between the cracks caused by subsidence in the walls without opening

Development of static analysis and relations between the cracks caused by subsidence in the walls without opening is necessary and unavoidable in the process of restoration of historical monuments, before preparing restoration plan and pathology. In other words, accurate and correct pathology, will determine the success of the restoration plan. Pathology process is an analytical issue which should be based on strong and correct arguments in order to achieve the desired result. the damages that requires reasoning and analytical studies include the cracks which were caused due to subsidence in the walls. Balance of forces of the building is disturbed by subsidence and subsequently, cracks are created. On the other hand, wall cracks can also endanger the stability and balance of the building structure in addition to cause instability by the subsidence, and accelerate the process of destruction by reducing the resistant cross-section of the wall. Therefore, analytical and static study of cracks caused by subsidence in the walls has a special and important place. For this reason, several researchers set to study and static analysis of cracks caused by the subsidence. They have obtained ratios and computations based on the length of the subsidence and height of the wall without opening for their detection and analysis. But the question always is whether obtained equations will suffice to analyze the cracks caused by subsidence in the walls without opening? In other words, is there any other types of subsidence and equations that has not been studied so far? So in answer to the question above, this study aimed to find new equations to expand and complement the existing computations in the cracks caused by subsidence in the walls without opening. The research method in this study is theoretical and static analysis and it is tried to be in connection with the studies of other researchers. According to this study another mode of subsidence can be considered in addition to other states which have been studied by other researchers. New equations and ratios were obtained with appropriate definition and static model analysis and consequently it was found that cracks form depends on the length of the subsidence.
