Abstract

Conventional design of PIERs is done by assuming fully rigid connection of deck to piles. In practice, these connections are semi-rigid. SEMI-RIGID CONNECTIONS cause changes in the dynamic characteristics of the structure such as natural frequencies and mode shapes. In this study experimental MODAL ANALYSIS performed on model of a PIER structure. Numerical model performed in ANSYS and MATLAB software. Determination of percentage of SEMI-RIGID CONNECTIONS considered as optimization problem based on numerical and experimental frequencies. Problem solved by PARTICLE SWARM OPTIMIZATION algorithm. By solving problem, percentage of rigid connection identified. For updating FINITE ELEMENT MODEL, linear elastic rotational springs employed instead of connections in theoretical model.
