Biblioverse - Multifunctional building with library
Řehořová, Jana ; Vala, Jiří (referee) ; Bykov, Oleksii (advisor)
Projekt pracuje s archaickým obrazem knihovny jako “chrámu vzdělanosti” a zároveň se snaží posunout její současný institucionální podtext založený na myšlence hromadění znalostí směrem k jejich pečlivému výběru a interpretaci. Dříve byly informace nedostatkovým zbožím a přístup ke vzdělanosti výsadou nepočetných společenských vrstev, úzce spjatých s mocí. Osvícenství a průmyslová revoluce přinesly v druhé polovině 19. stol. politické a technologické změny v šíření informací, které stále akcelerují. Strojní tisk novin a knih, vlak, telegraf a později telefon, jako předskokani digitálního šíření informací umožňily transportovat informace v množství a rychlostech do té doby nepředstavitelných. Vznikají moderní veřejné instituce a mezi nimi i veřejné knihovny, které mají zprostředkovat znalosti všem. Dnes se nicméně zdá, že to není touha po množství informací a znalostí ale snaha a potřeba rozumnět okolnímu světu, která je v lidské povaze neměnná. Práh, kdy zahlcení informacemi nepřispívá k hledání smyslu a vlastní pozice ve světě, je dnes součástí naší každodenní zkušenosti. Koncepce knihovny založená na hromadění a snadném vyhledávání informací se zdá být v době digitální komunikace nadbytečná, a princip, který fungoval dříve nemusí fungovat dnes. Zároveň fakt, že knihovny stále pracují primárně s mediem fyzické knihy, ukotvuje knihovnu v neaktuálnosti. Jako zprostředkovatel obrazu minulosti pak pomíjí přítomnost a její palčivá témata. Medium knihy lze na druhou stranu v digitálním světě chápat také jako největší výsadu knihoven, což z nich ale dělá jinou instituci. V projektu proto navrhuji nový koncept knihovny jakožto centra informačního managementu, jehož cílem je zpřístupnění informací validním způsobem. Knihovníci jakožto informační specialisté jsou zároveň kurátoři obsahu instituce i způsobu jeho “vystavení” veřejnosti. Knihovna tak přebírá principy jiných osvícenských institucí jako je muzeum a galerie. Knihovníci/kurátoři pracují s konkrétním aktuálním tématem, které během jeho expozice vyvrcholí v jeho veřejně dostupný organizovaný katalog. Vzniká tak kurátorský výběr informací k danému tématu – kolekce prezentovaná odpovídajícím způsobem odrážejícím aktuální očekávání a pohledy na svět. Aparát, který reaguje na současnost a podkládá ji minulostí. Místo, kde je čas zastavit a zamyslet se do hloubky nad vymezeným tématem.

Concretes reinforced by, using distributed steel reinforcements (fibres) are known as fibre-concrete. In case of disturbances or accidents of concrete structures reinforced with wires, it is necessary to carefully examine the actual implementation of dispersed reinforcement. Fibre concretes belong to modern building materials whose possible applications have not been fully utilized so far. Have been mainly used for floor structures loaded with factory halls and warehouses. Recently, thanks to well-known physical and mechanical properties of fibre-concrete, there were numerous attempts of designers, and namely investors, to utilize this kind of materials for support structures either. Favorable properties of wire-concrete can be utilized if there is a necessity to increase the resistance of concrete to stresses exceeding its strength, cyclic stress or impact stress. Daily practice shows to prove that the applications of fibre-concrete in such structures lead to the economic success. Necessary condition for successful application of steel fiber reinforced concrete in constructions however consists in its uniform dispersion, a homogeneous distribution of the wires throughout the volume of the structure. In case of inappropriate processing and deposition of the mixture during the manufacturing process fiber-concrete structures, the fibers are often unevenly distributed. Wires itself represent unfavourably shaped mixture components and they are extremely deteriorating its workability. A grouping of wires may be encountered as well, which reduces the overall homogeneity and the quality of steel fiber-concrete structures. If the homogeneity of fibre-concrete is not kept, the material possess different properties in various parts of the structure (for example, tensile strength), which can lead to defects in the structure (generation and development of cracks). The relevant lower reliability of the structure which is caused by unequal distribution of fibres (wires) in concrete volume can lead to damage of the property as well as the safety and the human lives can be jeopardized. Hence it is necessary to secure the effective control of the fibre-concrete homogeneity in ready support fibre-concrete structures. Contemporary homogeneity control is still ongoing on fresh blends, but if the fibre-concrete hardened and is a part of the construction, no known reliable methods are currently in available to test the homogeneity of the fibre-concrete on the structure without its destruction. The methods developed to control the concentration of wires in wire-concrete structures are based mostly on magnetic or electromagnetic properties of wires. The thesis deals with the development of the magnetic method in situ using permanent magnets for monitoring the distribution of fibers in hardened steel fiber-concrete structures. The test principle is based on measurements of the changes in magnetic field strength of permanent magnets which are induced by a change in wire distribution in steel fibre-concrete structure. Test is characterized as a so called local- failure- test using a small diameter core drill. In this sense it is a semi-destructive method.
