Each country is trying to prevent the destruction of its historic buildings and cultural heritage by applying various methods of reparation and retrofitting. Iran, as a country with an ancient civilization, is a heritage of many valuable historical monuments. Traditional construction materials included masonry materials such as clay and mud, stone, wood and brick, and due to the weakness in physical structure and their low shear capacity and tensile strength, these materials do not have strength for example against strong forces from earthquakes and are suffered heavy damages. Unfortunately, in our country, fundamental work has not been performed on historical sites and complexes so far, and practically, the measures have been taken without any improvement in the structural performance of the buildings. Using special technical and specialized methods, the seismic behavior of such buildings could be enhanced against the seismic forces caused by the earthquake, and minimize the damage on the historical buildings to the least possible extent by strengthening historical monuments. In this paper, by separating the components, we examine a number of strengthening methods belonging to each of them.","PeriodicalId":101901,"journal":{"name":"ISSUE SIX","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122196549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are aesthetically pleasing in appearance as well as the architectural requirement, in which tolerances of structural shape under changing service conditions are very significant, which high appearance accuracy is requested in some applications. Due to many reasons such as loading, these type of structures may suffer from a noticeable deflection, which leads to a significant potential undesired appearance of the shape. In this situation, the displacements may need to be reduced or eliminated. In this study, by applying the shape adjustment technique that its scheme is depend on the linear force method, shape restoration is performed to the double layer dome model in three different cases corresponding to the directions of loadings were considered. The improvement of controlling nodal displacement can be achieved through using a rather simple and direct method, due to calculating necessary length of actuators by applying a single formulation. It is found that if the number of provided actuators are satisfactory, controlling of all the displaced joints could be performed by a very small percentage of discrepancy, even if the controlled joints connection is not direct with the adjustable members. The technique of shape adjustment is very efficient for double layer dome model, and it can roughly eliminate the displacement of definite joints (Exterior joints only) by simply changing the length of certain bars by eo amount","PeriodicalId":101901,"journal":{"name":"ISSUE SIX","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126259817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
