This research is experimental study that precast beam connection which is modeled using steel plate. The result of this model design use to compare the occurence of structure deformity rigidity in monolith concrete construction (BN) and precast concrete (BP1 and BP2). The testing dimension consists of column with the size 300x300 mm and height 3300mm, beam 200x300 mm and width 3300 mm, with steel plate 200x400x8 mm and 300x400x8. This study resulted in monolith testing material (BN) produces average value 47.8 % from its previous rigidity, BP1is 57.13% from its previous rigidity, and BP2 is 52.22% from its previous rigidity.","PeriodicalId":356754,"journal":{"name":"EngRN: Structural Engineering (Topic)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117128618","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}

The level of knowledge of their structural behavior in presence of external actions is made through calculus methods and simple procedures in order to allow a reading of the material suffering degree and as a consequence of the related safety. Unfortunately, often the masonry panels show openings located in an irregular way and cracks having small or big dimensions. In these cases the employment of strategies, as for example the identifying of the masonry piers and the transformation of the wall as a frame, prove to be inapplicable. \u0000 \u0000Recently, a new method was introduced, called Boundary Element Method, which applied in its symmetric formulation, in virtue of some peculiarities, proves to be better usable in comparison with other analysis methods. In this paper an elastic analysis of walls, also in presence of geometrical nonlinearity consisting in the contact/detachment phenomenon among stone blocks. The wall having any shape and zone-wise variable physical characteristics is loaded in its plane. For these structures some interventions of structural strengthening have as aim to improve the wall behavior by reducing the stress concentration, so to have a better safety in comparison with its initial value.","PeriodicalId":356754,"journal":{"name":"EngRN: Structural Engineering (Topic)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132918105","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}
