Profile

Weikang got his bachelor’s and master’s degree from Tongji University in China in 2016 and 2019, respectively. His previous research is in the field of earthquake engineering, with his master thesis focusing on slab-damage-free self-centering connections equipped with SMA ring spring dampers.

Research

Currently his research topic is about assessment and prediction of fatigue behaviour of wrapped composite joints.

Weikang is working on the project of assessment and prediction of fatigue behaviour of wrapped composite joints for steel hollow sections. In this project an innovative jointing technology of wrapped composite joint is proposed to connect steel hollow sections by direct bonding through a fibre reinforced polymer composite wrap, which completely avoids welding and therefore has superior fatigue performance than welded joints. His project is funded by NWO.

Detailed description

Design and execution of fatigue load dominated circular hollow section (CHS) multi-membered  structures is hinged on fatigue performance of critical welded joints. In this project an innovative jointing technology of wrapped composite joint is proposed to connect steel hollow sections by direct bonding through a fibre reinforced polymer composite wrap, which completely avoids welding and therefore has superior fatigue performance than welded joints. Fatigue experiments combined with finite element analysis will be employed to quantify and predict fatigue behaviour of such joints. The objective is to establish framework for fatigue design verification of wrapped composite joints.
