Fire and structural performance of non-metallic timber connections

Brandon, Daniel January 2015 (has links)
Recent studies showed the need for timber connections with high fire performance. Connections of members in timber structures commonly comprise steel connectors, such as dowels, screws, nails and toothed plates. However, multiple studies have shown that the presence of exposed metal in timber connections leads to a poor performance under fire conditions. Replacing metallic fasteners with non-metallic fasteners potentially enhances the fire performance of timber connections. Previous studies showed that Glass Fibre Reinforced Polymer (GFRP) dowels can be a viable replacement for steel dowels and that Densified Veneer Wood functions well as a flitch plate material. However, as the resin matrix of GFRP dowels is viscoelastic, connection creep, which is not studied before, can be of concern. Also no research has been carried out on the fire performance of these connections. Therefore, a study of the creep behaviour and the fire performance of non-metallic timber connections comprising GFRP dowels and a Densified Veneer Wood flitch plate was performed, as is discussed in this thesis. Predictive models were proposed to determine the connection slip and load bearing capacity at ambient and elevated temperatures and in a fire. The material properties and heat transfer properties required for these models were determined experimentally and predictions of these models were experimentally validated. Furthermore, an adjustment of the predictive model of connection slip at ambient temperature allowed approximating the creep of the connection. The material properties, required for the creep model, were determined experimentally and predictions of the model were compared to results of longterm connection tests. The study confirmed that timber members jointed with non-metallic connectors have a significantly improved fire performance to timber joints using metallic connections. Models developed and proposed to predict fire performance gave accurate predictions of time to failure. It was concluded that non-metallic connections showed more creep per load per connector, than metallic connections. However, the ratio between initial deflection and creep (relative creep) and the ratio between load level and creep were shown to be similar for metallic and non-metallic connections.

Multifunkční centrum v Jihlavě / The multifunctional center in Jihlava

Sikorová, Radka January 2018 (has links)
The aim of this master thesis is to design and check a bearing structure of The multifunctional center in Jihlava. A bulding is partly ground flooring. The structure follows an L-curve in a plan with the biggest axial lenght of 40 m. A roofing is in a shed shape and the pitch of the roof is 5,73°. The highest point of the bearnig structure is 11,5 m. The structure has various frame systems, which is a truss, a gross-cross section beam with an inner column in the middle of a span and a gross-cross section beam without an inner column. The structure is designed mainly from timber members, a glulam and solid timber. A steel part of structure consists of the metal fasteners and rods.
