| Abstract [eng] |
In the contemporary landscape of pedestrian bridge design, there exists a dual imperative bridges must not only be aesthetically pleasing but also structurally resilient to support intricate architectural concepts. The demand for lightweight structures to realize these complex designs is clear, yet traditional materials and production methods often fall short of meeting the multifaceted challenges. Inner structures, made possible through additive manufacturing techniques, have the potential to act as dynamic modifiers, enabling precise control over the structural response. The aim of the work is to develop a structurally adaptable lightweight lattice core sandwich component using additive manufacturing techniques. The master's thesis consists of 3 main parts: reviews of the development and analysis of additive production compatible components for light pedestrians bridges in literature; geometric core design; obtaining experimental studies and diagrams of geometric core samples; Numerical modeling of geometric core samples and results obtained. Experimental (6 geometric cores were tested) and numerical (using computer programs SOLIDWORKS, ZEISS CORRELATE) methods were used for the research. The obtained results showed that the best behavior corresponded to the honeycomb core. The results of the experimental and simulation part showed that the software parts can estimate the behavior of the beams well. Master's thesis consists of 69 pages, that include 57 figures, 9 tables and 27 literature sources. |
