  • Masonry constructions exhibit uncertain behaviors under dynamic effects such as seismic action. Complex issues arise in the idealization of structural systems of buildings having different material types and mechanical properties. In this study, the structural behavior of a vaulted masonry building constructed using full clay brick and lime-based mortar and sitting on consecutive arches was investigated by experimental and numerical approaches. The dimensions of the structure built in the laboratory were 391 × 196 cm, and its height was 234 cm. An incremental repetitive loading was applied to the prototype construction model. Along the gradually increasing loading pattern, the load-displacement curves of the masonry structure were obtained with the assistance of eight linear displacement transducers. In addition, crack formation areas, and relevant causes of its formation were determined. The experimental model was idealized using the finite element method, and numerical analyses were performed for the area considered as linear being under similar loading effect. From the linear analyses, the displacement values and stress distribution of the numerical model were obtained. In addition, the effects of tie members, frequently being used in the supports of curved load-bearing elements, on the structural behavior were examined. Consequently, the experimental and numerical analysis results were comparatively evaluated.

  • In this research, the case of modern wooden structures since 1950 with span of 30m or more was investigated and analyzed the construction status and structural planning characteristics of wooden large space architecture. As a result, wooden large space buildings have built around Asia, North America, and Europe, in which cases of ice skating stadiums with span of 30m to 60m were concentrated. In the case of baseball parks and football stadiums, even a span of about 165m was built in a wooden structure. In addition, it was found that the structural systems used in wooden large space structures were a funicular arch and truss structure, in that cases, funicular arch system consisting of radial arrangements was used in the examples exceeded 150m and the two way truss system was also used in long span wooden structures exceeding 100m. As the truss structure with a tie-rod or the flexure+tension structure was partially investigated, it can be seen that various timber structural systems need to be devised and researched. Also, It was investigated that a technique in which some members of the truss are made of steel or a composite member of steel and timber is also possible to develop
