Yes / This study investigates the bending performance of ultra-high-performance concrete (UHPC) beams reinforced with non-prestressed steel-FRP composite bars (SFCBs) and prestressed fiber-reinforced polymer (FRP) bars. The finite element software ABAQUS was used to simulate the strain behaviors of materials, applying a real strain model for concrete and equivalent plastic strain models for reinforcements. Six beams with different concrete types and reinforcements (prestressed or non-prestressed) were simulated and analyzed. These simulations yielded results that closely aligned with the results tested. Based on the validated FE models, a parametric analysis was conducted to examine the effects of mechanical properties of concrete, mechanical property of non-prestressed reinforcement, and the reinforcement ratio of prestressed FRP bars and non-prestressed SFCB on the bending performance of SFCBs reinforced UHPC beams prestressed with FRP bars. The results indicate that, as the concrete strength increases from C35 to UHPC140, both the bearing capacity and ultimate deflection of flexural beams exhibit a gradual increase. Notably, employing UHPC100 as the matrix results in specimens achieving the highest ductility, deformation, and energy absorption. When non-prestressed FRP bars are replaced by SFCBs, the ultimate load of the beams decreases by 8%, but energy absorption increases by 34%. With an increase in the steel ratio of SFCBs, the ductility, deformation, and energy absorption also gradually increase. Moreover, increasing the reinforcement ratio of both prestressed FRP and non-prestressed SFCBs results in an increase in bearing capacity, but a decrease in ultimate deflection, ductility, deformation, and energy absorption capacity. This research can provide valuable technical references for the analysis and design of UHPC beams reinforced with SFCBs and prestressed FRP bars. / Financial support from the National Natural Science Foundation of China (52378201),the High-End Foreign Experts Project of Ministry of Science and Technology, China (G2022014054L), the Jiangsu Construction System Science and Technology Project (2023ZD104 and 2023ZD105), the Nantong Jianghai Talents Project (226), the Science and Technology Project of Yangzhou Construction System (202309 and 202312) and the Research Project of Jiangsu Civil Engineering and Architecture Society (the Second Half of 2022).

Master’s thesis describes the structural design and static analysis of selected elements of prefabricated reinforced concrete industrial building, that will be used as storage hall. Purpose of thesis is elaboration of assembly drawings of the project documentation and drawings of formwork and reinforcement assembly of selected elements. Calculations were performed in computer programs for static analysis SCIA Engineer 16, IDEA StatiCa and FIN EC. Drawing were made in programs Allplan 2016 and AutoCad 2015.

The content of the thesis is a static design of the supporting parts of the extension of the textbook pavilion of the elementary school in Mirošov. The proposed building is a four-storey reinforced concrete monolithic column construction. The ceilings above the first three floors are designed as cross-reinforced slabs with internal girders. The roof slab consists of a monolithic slab with additionally prestressed beams. The internal forces were calculated using SCIA Engeneer 19.0 and these values were subsequently verified by manual calculation. The design followed the applicable European standards. The result of the work is a static assessment of the object and corresponding drawing documentation.

Master’s thesis is based on analysis and design of a load bearing structure of an mountains hotel. Mountain hotel schould be realized in the village Vernirovice in Šumperk district. The proposed structure is formed 4th floors. In 1.NP is a restaurant, a sports and wellness center. In 2.NP in the right side is situated the swimming pool. In 2 to 4 floor are located rooms. This structure is supported with a strip footing made of reinforced concrete. The main load-bearing elements in the vertical direction are in 1.NP reinforced concrete walls and columns, the upper floors bearing masonry walls of ceramic blocks THERM. The inner support walls are 300 mm thick, outside support walls are 400 mm thick. Floors are constructed of carrying plates with girders above the larger openings. These plates and girders are made of reinforced concrete. In the 2 floor are beams with the span of 8,8 m. These girders are designed of prestressed concrete cause the large loads. Individual levels are connected with monolithic concrete staircases. Around the middle of the building is a monolithic reinforced concrete elevator shaft. The highest elevation above grade level is 16 m. The thesis also deals with relevant drawing documentations for chosen parts of construction.The building is located in the ski area VI and IV wind areas.
