Characteristic curves of the influence of the reinforcement percentage on the bearing capacity, deformability are given, character of settlements of the investigated soil massin time at step-increasing loading are shown. It was found that depending on the percentage of reinforcement the critical pressures increased linearly and the values of settlement at critical pressures were determined increased with the base reinforcement percentage. Empirical dependencies were obtained to determine the critical pressures depending on the percentage ofreinforcement for the investigated soil conditions.

In particular, it is possible to analyze the reliability of the most likely failure mechanism. Separate assumptions that determine the sequence of application ofthe limit equilibrium method are presented. A method for determining the reliability of statically indeterminate steel framesin the plastic stage is presented. This method provides an opportunity to determine the probable mechanism of destruction.The ultimate equilibrium method is used to calculate the forces at the final stage of destruction. In the work, the real mechanism of destruction is understood as a mechanism for which the work of external forces to create it is the least. It is revealedthat the real mechanism of destruction is approaching the beam or floor elementary mechanism.","PeriodicalId":32910,"journal":{"name":"Zbirnik naukovikh prats'' Seriia Galuzeve mashinobuduvannia budivnitstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77751538","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}
