In contrast to the native soil, the main component of the overall settlement of waste is secondary compression. Therefore, the determination of the secondary compression index (Cα) or modified secondary compression index (Cα') is especially important. This paper presents some of laboratory results for municipal waste consolidation tests method as well as their role in settlement analysis of waste material. Sample tested was prepared artificially in line with the recommendations for sizes of the apparatus used and the largest particles in a sample (EN 1997-2, ASTM 2007a, 2007b). Different conventional models for prediction of municipal waste settlement were used settlement analysis was performed using the parameters of compressibility.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":"4 1","pages":"32-42"},"PeriodicalIF":0.2,"publicationDate":"2013-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66265802","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}

Ostecenja stropova manifestirala su se odlamanjem dijelova supljih opecnih blokova, sto je ugrožavalo sigurnost ljudi. Uporabom optickog mikroskopa i elektronskog mikroskopa, kao i kemijske mikroanalize EDS (Energy Dispersive System), analizirana je ostecena keramika te je utvrđena prisutnost iskristalizirane soli. EDS analizom utvrđena je prisutnost kemijskih elemenata (Al i S), koji uz utvrđenu morfologiju kristala ukazuju na mogucnost prisutnosti minerala etringita (Al2O33CaSO4 x 32H2O). Numerickom analizom uz primjenu metode konacnih elemenata, uporabom racunalnog programa COSMOS Design STAR 3.0 od SRAC (Structural Research and analisis Corporation USA), procijenjen je utjecaj temperaturnih opterecenja na koncetraciju naprezanja na vrhu mikropukotina i na njihovo sirenje. U numerickoj analizi eksperimentalno su uzeta u obzir određena fizikalno- mehanicka svojstva materijala. Analizirani su primjeri supljih opecnih blokova s prisutnoscu bijelih kristala i bez njih. Prikazan je raspored faktora sigurnosti po modelu u odnosu na Mises-ovu hipotezu razaranja. Rezultati eksperimentalnih i numerickih istraživanja pokazali su da kemijska degradacija supljih opecnih blokova, u kombinaciji s temperaturnim opterecenjem koje nastaje zbog promjena klimatskog režima, može uzrokovati takva ostecenja te da je time ugrožena i sigurnost konstrukcije.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":"4 1","pages":"96-107"},"PeriodicalIF":0.2,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66265698","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}

One of such solutions is a composite truss system, which is the subject of this paper. This type of construction has advantages t hat can be utilized in medium and large spans, and in comparison to steel trusses has a lower height. When it is combined with trapezoidal sheets for composite slabs it provides a number of practical advantages.
