Investigation on The Seismic Behavior of Steel MRF with Shape Memory Alloy Equipped Connections
No full textAbstractShape Memory Alloys (SMA) are among the new passive control devices that have gained a large attention due to its inherent features, i.e., recovering the induced residual strains upon unloading (superelastic effect) or by heating (shape memory effect). In this work, the seismic behavior of a set of steel structural models with different number of stories and eccentricities equipped with a type of fixed SMA connections is investigated. Considering an existing SMA connection model in austenite phase, the related moment-rotation behavior is verified through numerical simulation. Then, extensive nonlinear dynamic analyses are performed using a number of 3, 6, 9, and 12 story structural models with 0, 5%, 10%, and 15% eccentricities subjected to different bi-directional earthquake components. The PGA of the earthquake records is scaled to 0.4g and 0.6g to examine the energy dissipation capability of the SMA materials. Similar analyses performed using the same set of structural models, but with all beam-tocolumn connections equipped with SMA connections. The obtained results indicate that while the reduction in drifts of the SMA equipped models with respect to the fixed connection models was not noticeable, their base shears were considerably reduced. The OpenSees program is used for modeling of the connections with SMA materials and performing the numerical analyses
On the Performance of Passivr TMDs in Reducing the Damage in 2-D Concrete Structural Models
No full textAbstractPozzolanic materials, either naturally occurring or artificially made, have long been in practice since the early civilization. In recent years, the utilisation of pozzolanic materials in concrete construction has become increasingly widespread, and this trend is expected to continue in the years ahead because of technological, economical and ecological advantages of the materials. One of the latest additions to the ash family is palm oil fuel ash, a waste material obtained on burning of palm oil husk and palm kernel shell as fuel in palm oil mill boilers, which has been identified as a good pozzolanic material. This paper highlights test results on the performance behavior of palm oil fuel ash (POFA) in reducing the heat of hydration of concrete. Two concrete mixes namely OPC concrete i.e. concrete with 100% OPC as control, and POFA concrete i.e. concrete with 30% POFA and 70% OPC were prepared, and the temperature rise due to heat of hydration in both the mixes was recorded. It has been found that palm oil fuel ash not only reduced the total temperature rise but also delayed the time at which the peak temperature occurred. The results obtained and the observation made clearly demonstrate that the partial replacement of cement by palm oil fuel ash is advantageous, particularly for mass concrete where thermal cracking due to excessive heat rise is of great concern

No full textForms of judaism in writings of F.R. Kraus, František Kafka, Hana Bělohradská and J.R. Pick
No full textTéma této práce zní Podoby židovství v dílech F.R. Krause, Františka Kafky, Hany Bělohradské a J.R. Picka. Soustředila jsem se na méně známé české autory, kteří se ve své tvorbě věnovali tématu židovství. Jedná se o texty související s 2. světovou válkou. V úvodu je nastíněn stručný přehled o působení Židů na našem území, následuje představení zvolené čtveřice autorů. Hlavním cílem bylo přiblížit a rozebrat vybraná díla a v závěru shrnout jejich odlišné a podobné znaky. Současně byly tyto texty zařazeny do kontextu české prózy s tematikou okupace.Katedra českého jazyka a literaturyObhájenoThe theme of this bachelor work is called Forms of judaism in writings of F.R. Kraus, František Kafka, Hana Bělohradská and J.R. Pick. In this thesis the author tried to concentrate on a few less-known Czech writers, who devoted their writing to the fate of Jews during the Second World War. In the first part of this work the author outlined the influence of the Jewish etnic group on the population of our country, with the aim to gain orientation in the historical backgound of that time. Next the author analysed the texts of selected books with the Jewish theme from different points of view and in the end of her work compared the books she used. In the closing of this work there is a contextual classification of the mentioned books into the category of works with the topic of occupation, from the end of the Second World War until today
