NUMERICAL AND EXPERIMENTAL SEISMIC PERFORMANCE EVALUATION OF THE NEW CONCEPT OF PRECAST CONCRETE CONECTIONS

摘要

This paper aimed to introduce a new concept of precast concrete connection for the purpose of mass construction for low-rise buildings. Performance of connection was assessed based on FEMA 356 and the level of ductility has been calculated. Also to find the practical guideline for using of this connection, numerical evaluation has been carried out and compared with full scale tests results. Results shows that connection can be used for ordinary level of ductility based on ASCE7-2010 and to predict the realistic elastic deformation the moment of inertia modifier should be applied. Also special safety factor to achieve the expected performance shall be considered for some parts of the connection. Conclusion shows a good correlation with previous researches and confidence for the use of current design procedures with proposed modifications in this paper.
