| Abstract [eng] |
The development of the ZI method software, checking of the effectiveness and application in designing of port structures has been presented in the master‘s thesis. In the theoretical review section, literature sources have been reviewed and analyzed, as well as the ZI method, which was created by professor I. Židonis as continuity of professor A. Rozenbliumas researches. Also, other analytical and numerical methods, developed by scientists, for investigating material nonlinearities, have been described and analyzed. In the second section, algorithm according to which calculations are performed, is represented as well as analysis and explanation of the ZI method methodology and formulas used in it. The ZI method automated calculator developed by MAPLE software is presented in the annexes. In the third section, calculations of mechanical state parameters have been performed for concrete and reinforced concrete cross sections without cracks by the ZI method, the Lithuanian design code STR and the finite element method, using ANSYS software. Comparison of the results and conclusions have been presented. Also, analysis of the reinforced concrete cross section with cracks by the finite element method, according to the experimental data, were performed. Description of the model, results and conclusions have been presented. In the last section, bearing capacity for the upper reinforced concrete slab of the bulk warehouse underground duct, has been calculated by the ZI method, Lithuanian design code STR and the finite element method, using STAAD.Pro software. Comparison of the results and conclusions have been presented. The final thesis consists of 102 pages, 89 pages of annexes, 8 tables, 65 pictures and 43 literature sources. 2021 participated in the “Industrial Engineering 2021” conference, prepared article and presented the report in English for the audience. |
