Evaluation of Ductility of Precast Column Foundation Connections

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 Paulay (1989) The results were also compared with monolithic specimen. Each specimen subjected displacement-controlled lateral cyclic loading. maximum displacement maintained at 40 mm due laboratory constraints. Findings: results, 31- 03 gives better values than Park. calculated 31-03 31.5 %, 41.07 72.7%, 68.3% 48.9 % higher specimen, PCBJ, PC I, II GS respectively. Novelty: present study reveals best-suited that can be applied evaluate loading has not been reported in earlier studies.
