Este trabalho apresenta uma proposta de método de ensaio para determinação da resistência de ligações em peças estruturais de madeira por chapas com dentes estampados e também verifica os modos de ruptura destas ligações. Para esta finalidade foram realizados ensaios com 5 (cinco) espécies de madeira classificadas de acordo com as classes de resistência apresentadas no projeto da nova norma brasileira para estruturas de madeira, a PNBR 7190/1996 - Projeto de Estruturas de Madeira. No trabalho são verificados 3 (três) modos básicos de ruptura das ligações, a saber: tração da chapa, cisalhamento da chapa e arrancamento dos dentes da chapa da peça de madeira. Dentro de cada modo de ruptura verifica-se os efeitos da variação da posição da chapa em relação à direção de aplicação da força. Determina-se também a resistência da ligação de acordo com o proposto pelo projeto da nova norma brasileira para estruturas de madeira (PNBR 7190, 1996). / The aim of this work is to propose a test method to determine the strength and to verify failure modes of timber joints made with metal connectors plate. To this purpose, several tests were made with 5 species of wood, which were classified according to the strength class introduced in the new Brazilian Standard for Timber Structures, NBR 7190/1996 - Timber Structure Project. In this work are verified 3 failure modes: metal connector plates under shear force and pure tension force, and lateral resistance strength of metal connector plate teeth. For each failure mode is verified the effect of the position of the plate under the direction of force. The resistance of joints are determine in agreement to the new Brazilian Standard for Timber Structures.

Master’s thesis deals with complete project documentation of newly built object of library and mediatheque located on the site in České Budějovice. It is a three-storey building divided into three parts, one-storey, two-storey and three-storey. It is partly basement. The underground part is devoted to main storage spaces of library services, management offices and social facilities for staff (toilets, changing rooms, washrooms). This part of the building has own entrance for employees. In the 1st floor is located the main library area along with exhibition spaces and the main entrance for visitors with self service cloakroom. In the 2nd floor are designed library spaces for visually impaired persons with fund of audio books, CDs and DVDs, a lecture hall with a projector and own kitchen and space for reading magazines and periodicals. From this floor is possible access to the outdoor terrace, which has own terrace furniture store nearby. In the 3rd floor is located a literary café with its own facilities. In each floor are also designed sanitary facilities for use by persons with limited ability of movement and orientation. All floors are connected by stairs and passenger lifts. In terms of construction, the building is designed as a frame, in the underground parts made of reinforced concrete, the overhead of glued laminated timber elements. The ceiling structure designed over the underground floor is monolithic reinforced concrete slab. The ceilings in the upper part are designed as a wooden beamed made of the glued laminated timber elements. The building has a pent roof created by wooden trusses assembled with punched metal plate fasteners. The foundations are designed as belts and footings. The study, detailed documentation, thermal-technical evaluation of selected structures and fire safety of the building are processed. For processing of the thesis were used software AutoCAD 2010, Teplo 2011, Area 2011, Ztráty 2011 and Fire NX 802 PRO.
