Objectives: To investigate and compare the ductility performance of precast column foundation connection using method proposed by Park ASCE 31-03. Methods: Strength are most important parameters to resist earthquake forces for overall safety a structure. Evaluating from experiments is cumbersome process. From experimentally obtained load-displacement envelope, was evaluated four specimens Paula...

The present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. Performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. This new optimization concept is carried out for unbrac...

The structural integrity of precast concrete buildings depends mainly on the connections between the precast structural components. Large precast concrete panels are used extensively in North America for low, medium, and highrise construction due to their ease and speed of assembly, and high quality control. This paper presents the results of twenty-two prototype specimens tested to investigate...

Plentiful studies are reported on the semi-rigid behavior of joints between open section H shaped beam and column, but researches focusing on the semi-rigid performance of joints between square/rectangular hollow section (SHS/RHS) column-to-H shaped beam is to lag a lot. Most studies shows that when the SHS/RHS column connecting the H beam without internal diaphragm, the joints behavior is semi...
