000018557 520__ $$2eng$$aDowel connections are the most common type of the beam to column connection, which are typically used in precast industrial buildings in Europe. Nevertheless, the knowledge about their seismic behavior was recently relatively poor as long as they were examined in the frame of the European FP7 project SAFECAST - Performance of Innovative Mechanical Connections in Precast Buildings Structures under Seismic Conditions. One of the results of this research were new formulas, which can be used to predict the force-displacement response of dowel connections. Due to their simplicity they can be used in the design practice. These formulas take into the account several important parameters influencing the strength and deformation capacity of dowels, such as: an amount of the confining reinforcement in the adjoining precast elements, the position of the dowel, the level of relative rotations between the beam and the column, etc. Exploiting the newly obtained knowledge, robust macro numerical models for dowel connections were proposed. These elements were used in the extensive probabilistic dynamic parametric studies of precast industrial buildings. A set of 15 single-storey industrial buildings was carefully selected in order to cover the wide range of typical buildings. All these structures were designed for peak ground acceleration of 0.25g and soil of type C according to Eurocode 8. Each building was designed considering three different types of dowel connection, which differed regarding the amount of the confining reinforcement in the adjoining precast elements and the position of the dowel. The conditional probability of failure was calculated for all buildings and for all dowel connection details taking into the account both, record-to-record variability and modelling uncertainties. The results of the seismic fragility analysis clearly illustrate the importance of the confining reinforcement constructed in the area around the dowel as well as the importance of the distance of the dowel from the edge of the connected precast elements.
