Estimations were performed using regression, single and multiple donor stations based drainage area ratio, standardization with mean (SM), standardization with mean and standard deviation (SMS), inverse distance weighted methods. Two seperate studies were conducted for both partially missing data and completely missing data. In order to estimate streamflow statistics for use in SM and SMS methods, logarithmic regression equations were suggested. The promising results obtained from ensemble approaches will provide a significant hydrological contribution to streamflow estimations.","PeriodicalId":49442,"journal":{"name":"Teknik Dergi","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46927545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One compliance aspect is the load-bearing function, which in a large degree depends on the floor structures. As old masonry buildings often have timber floors, the purpose of this article is to provide an insight into the field of timber floor strengthening. Thus, the evolution of floor structures is compactly presented, and common types of timber floors are given. Furthermore, the weight of different timber floor fillings is studied in relation to the prescribed imposed loads. Measures for strengthening old timber floors are introduced separately for vertical and horizontal strengthening. Additionally, a classic timber floor and a timber-concrete composite floor are analyzed according to the current building standards in the European Union, the Eurocodes.","PeriodicalId":49442,"journal":{"name":"Teknik Dergi","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46331601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
