Estimation of Minimum Torsional Reinforcement of Reinforced Concrete and Steel Fiber-Reinforced Concrete Members

Ju, Hyunjin; Han, Sun-Jin; Zhang, D.; Kim, Jong R.; Wu, Wei; Kim, Kang Su (Hindawi, 2019)

The current code specifies a minimum torsional reinforcement ratio to prevent possible brittle failure after torsional cracking in concrete members. However, since there are many researches, in which even the concrete ...
Experimental Study on an Optimized-Section Precast Slab with Structural Aesthetics

Ju, Hyunjin; Han, Sun-Jin; Choi, Il Sup; Choi, Seokdong; Park, Min-Kook; Kim, Kang Su (MDPI, 2018-07)

The optimized-section precast slab with structural aesthetics (OPS) is a half precast concrete slab with multi-ribs that optimizes the cross-section by eliminating the unnecessary bottom flanges at mid-span and has good ...
Flexural Responses of Prestressed Hybrid Wide Flange Composite Girders

Han, Sun-Jin; Lee, Deuck Hang; Oh, Jae‑Yuel; Choi, Seung‑Ho; Kim, Kang Su (SpringerOpen, 2018-08)

In this study, prestressed hybrid wide flange (PHWF) composite girders were proposed, and full-scale flexural tests were conducted to evaluate their structural performances. This new proposed girder system was developed ...
Web-Shear Capacity of Thick Precast Prestressed Hollow-Core Slab Units Produced by Extrusion Method

Park, Min-Kook; Lee, Deuck Hang; Han, Sun-Jin; Kim, Kang Su (SPRINGEROPEN, 2019-01-25)

The prestressed hollow-core slab (PHCS) is a precast concrete member that can maximize productivity and structural performance efficiency of concrete cross-section. For the PHCS members produced by extrusion method, however, ...
