研究室紹介
Professor Myoungsu Shin's research lab specializes in advanced concrete materials and structural engineering, with a focus on improving the seismic performance of reinforced concrete structures through innovative analysis methods and smart materials. The lab investigates the behavior of beam-column joints under cyclic loading, develops conductive cement composites for self-healing and accelerated curing applications, and explores practical finite element modeling techniques for real-world structural systems. A key emphasis is placed on bridging the gap between laboratory research and field implementation, particularly in enhancing durability and sustainability of civil infrastructure.

15In seismic analysis of moment-resisting frames, beam-column connections are often modeled with rigid joint zones. However, it has been demonstrated that, in ductile reinforced concrete (RC) moment-resisting frames designed based on current codes (to say nothing of older non-ductile frames), the joint zones are in fact not rigid, but rather undergo significant shear deformations that contribute greatly to global drift. Therefore, the "rigid joint" assumption may result in misinterpretation of the
This study aimed to investigate the self-heating characteristics of electrically conductive cement composites (ECCCs) and propose an effective and affordable mix design for ECCC blocks that are applicable to the accelerated curing of concrete with carbon black and carbon fibers employed as conductive agents. Twelve mix proportions were prepared by varying the carbon black and carbon fiber contents. A voltage application protocol was designed and used to examine the self-heating capacities of the
At the ACI Fall 2008 Convention, Joint ACI-ASCE Committee 447, Finite Element Analysis of Reinforced Concrete Structures, and ACI Committee 118, Use of Computers, will cosponsor a two-part session titled ???Practical Use of Finite Element Analysis in the Design of Concrete Structures.??? One of the presentations in the session will cover the modeling of a 25-story hotel building being constructed together with a 60-story residential tower in New York City. The project and its modeling are discus
Recently, self-healing technologies have emerged as a promising approach to extend the service life of social infrastructure in the field of concrete construction. However, current evaluations of the self-healing technologies developed for cementitious materials are mostly limited to lab-scale experiments to inspect changes in surface crack width (by optical microscopy) and permeability. Furthermore, there is a universal lack of unified test methods to assess the effectiveness of self-healing te
Four two-thirds-scale reinforced concrete edge beam–column–slab subassemblies (two concentric and two eccentric connections) were tested under quasi-static cyclic lateral loading. Each subassembly represented a cruciform connection in an exterior moment-resisting frame with a monolithic floor slab on one side only, loaded in the longitudinal direction of the edge-beams. The tests explored the effect of eccentricity between beam and column centrelines, and the effect of floor slabs, on the struct
