Numerical models of arch specimens are semi-automatically developed from Structure-from-Motion (SfM) photogrammetry, by employing image processing techniques (IPTs) to bypass laborious CAD-based processes. Then, the numerical models of the proposed framework are assessed by comparison to a conventional CAD-based framework in terms of: a) geometrical agreement (i.e., joint and block properties); and b) structural capacity agreement (i.e., stiffness, load multipliers and normal forces between joints at each hinge formation). Results firstly demonstrated SfM photogrammetry as an effective avenue of structural surveying for numerical modelling. After, the numerical models developed from the proposed and conventional framework were demonstrated to have a good agreement in terms of geometry. Furthermore, good agreement was also found in the predicted structural capacity, with differences in structural capacity of less than 7% Although only the potential to capture both the geometry and structural capacity of small-scale arch structures was demonstrated here, this study lays the foundation for automated geometry acquisition for arches for their structural analysis.","PeriodicalId":42072,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Engineering History and Heritage","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47188334","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}

It was developed further by increasing the push-down force to provide a method of designing piles. During the 1940’s improvements were made by increasing push-down force, also improving probe geometry and test procedure. One of the most important developments of the CPT was made in Indonesia by Dutch engineers in the 1950’s, who added the friction sleeve used to measure local friction. The data from this device was used in an empirical design method to determine the bearing capacity of friction piles. The device became known as the “mechanical CPT” and has now been superseded by probes with the same basic dimensions, but with loads and pressures measured locally using transducers. The modern “electric CPT” offers significant advantages, however there are still places where the mechanical CPT is used widely, such as in Indonesia. It should be appreciated that there can be significant differences in the measured parameters, such that awareness of the type of probe being used is important, as are the methods of interpretation.","PeriodicalId":42072,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Engineering History and Heritage","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43894923","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}
