Title: Experimental insights into high-performance fibre-reinforced cementitious composites (HPFRCCs) as retrofitting materials in reinforced concrete columns Authors: Keat Bin, Teoh; 오택근; Shack Yee, Hiew; Kyung-Hwan, Min; Hyun-Oh, Shin; Doo-Yeol, Yoo Abstract: Structural retrofitting has become a key strategy in decarbonisation efforts within the construction sector. High-performance fibre-reinforced cementitious composites (HPFRCCs) have emerged as promising retrofitting materials due to their superior mechanical performance and durability. This study investigates the effectiveness of two types of HPFRCC – ultra-high-performance concrete (UHPC) and high-performance strain-hardening cementitious composites (HPSHCC) – for retrofitting reinforced concrete (RC) columns subjected to varying levels of transverse reinforcement. To evaluate the improvements provided by the retrofitting systems, the resulting failure modes were compared and the experimentally measured global and local strain responses were examined. To further characterise the contributions of the retrofits, the behaviour associated with cover spalling, the analytically derived confined core response, and the post-peak deformability were also analysed. To this end, this study provide insights into the confinement efficiency of the HPFRCC retrofits and their influence on the overall ductility and toughness of retrofitted columns relative to conventional RC columns. Finally, the applicability of existing design code provisions is assessed for predicting the cross-sectional compressive resistance of the HPFRCC-retrofitted columns investigated in this study.

Title: Identification-Based Simultaneous Reduction of Tangential and Normal Force Ripples in PMLSMs Under Dynamic Operation Authors: 이상민; Kwon, Yoon Sik; Jung, Jae Heon; Kang, Kyujin; Kim, Chang Hwan; Yoon, Jun Young Abstract: The iron-cored permanent-magnet linear synchronous motors (PMLSMs) are increasingly in demand with advantage of high force density and direct-drive capability. However, inherent force ripples caused by the magnetic saliency not only degrade the servo accuracy, but also induce vibration and noise, particularly during high-acceleration operations. This article presents a control-based force ripple reduction method to address such issues, by adjusting DQ-currents to counteract both tangential- and normal-direction force ripples simultaneously. Using an established motor force model, compensation DQ-currents are derived to generate additional forces that actively cancel out the force ripples. To enable effective compensation, experimental identification methods are developed to determine the force parameters required for the ripple reduction method, achieving a maximum identification error of less than 10 %. With these identified parameters, the proposed method experimentally achieves a reduction of over 87 % in the RMS value of tangential-direction force ripple and 69 % in the normal direction, all while maintaining constant motor thrust.
