Title: Innovations of Cheng-Chih Chen in Seismic Engineering

Introduction

Cheng-Chih Chen is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of structural engineering, particularly in seismic-resistant designs. His innovative approach addresses critical challenges faced during severe earthquakes.

Latest Patents

Cheng-Chih Chen holds a patent for a seismic-resistant beam-to-column moment connection. This invention features a structural steel connection equipped with a pair of rib plates installed symmetrically above and below the connection. The rib plates are oriented perpendicularly to the upper and lower beam flanges and are positioned to align with the center of the beam web. The rib has a variable cross-section at its front end and a relatively longer section at its rear end. This design alleviates stress concentration at the fan-type weld access holes of the beam web and the junction of the full penetration weld between the beam flange and column flange. It effectively limits the plastic hinge to a specified portion of the beam, allowing for excellent plastic rotation capacity during severe earthquakes.
