The difficulty lies in how to apply the treatment without destroying the old components and the original design of the building. The treatment processes take place by the classification of the type and the value of the building, then the determination of the deterioration level decides the level of intervention. The aim of the research is to provide a method for assessing the ways of preserving the architectural and urban heritage, which includes all the factors that affect the preservation of the heritage so as to access that it contributes to access to the deficiencies in the ways of preserving the heritage and to build a plan for action to avoid them in the future. The research followed a causal comparative research approach that began with an analytical study to determine the factors affecting preservation and its considerations, by collecting and analyzing the data of the most important international and national charters and recommendations for the preservation. This study defined the preservation works into 4 levels of interventions passed on the intervention objectives, building's physical state, causes for the deterioration and maintenance works. By comparing the deterioration level with the intervention level for the conservation procedures, the result indicates the suitability of the work performed. This result could be number between 4 and -4.展开更多

The results show that we can get actual velocity and displacement time histories by simulating broadband acceleration records. The acceleration and displacement time histories also may be obtained by simulating broadband velocity records.
