Journal of Korean Society of Steel Construction, volume 14, issue 2, 2002, Pages 349~356
Cold-Formed C-section and Lipped C-section are commonly used as structural members of steel houses in Korea. Both are made of SGC41 steel. However, special Cold-Formed Sections with unique cross sectional shape have been developed and widely used in advanced countries. This research focused on the newly developed thin-walled Cold-Formed Sections which possess not only high strength and stiffness but also other advantages in construction. A series of compression tests was conducted to investigate the structural behavior of a compression member, including its load carrying capacity. Test results were compared with analytical study results.
Structural Behavior of Newly Developed Cold-Formed Steel Sections(II) - Flexural Behavior

The study performed a series of flexural tests on Closed Cold-Formed Steel Sections for stud, joist, and roof truss. Results were compared with analytical values. Each 2.4-m long and 0.9-m wide specimen consisted of two steel beams set at 0.46 m interval. The steel beams were attached to the specimens using either plaster board or ply wood. Another specimens did not use any attachment material. Positive and negative bending tests were conducted to investigate the composite behavior, including the effects of plaster board or ply wood on the buckling behavior of steel beam. Full-scale roof truss tests were also performed to study the buckling behavior and failure mode of the truss members.
Lifetime Prediction of Existing Highway Bridges Using System Reliability Approach
Yang, Seung Ie ;
Journal of Korean Society of Steel Construction, volume 14, issue 2, 2002, Pages 365~373
In this paper, the system reliability concept was presented to predict the lifespan of bridges. Lifetime distribution functions (survivor functions) were used to model real bridges to predict their remaining life. Using the system reliability concept and lifetime distribution functions (survivor functions), a program called LIFETIME was developed. The survivor functions give the reliability of component at time t. The program was applied to an existing Colorado state highway bridge to predict the failure probability of the time-dependent system. The bridge was modeled as a system, with failure probability computed using time-dependent deteriorating models.
Experimental Study on the Infilling Characteristics of CFT Column Infilled by Pumping-Up Below
Kim, Myoung Mo ; Jeon, Sang Woo ;
Journal of Korean Society of Steel Construction, volume 14, issue 2, 2002, Pages 375~383
To evaluate the applicability of the construction method involving infilling CFT columns by pumping-up, a trial construction was done using 6 actual size test samples. The 12.8m-high test samples were similar to a four-story building scale. The pumping-up level was controlled at 12m. The test used two types of high performance concrete with
standard design strength, and a concrete pump which is used domestically. The pressure changes in pipes or pump as well as the changes in concrete characteristics were measured during construction. in order to evaluate applicability. After the concrete hardened, the column was dismantled. The filled state of the concrete, concrete strength distribution according to column height, etc., were checked to evaluate the quality of the concrete, From the results, some basic data which characterize the pumping-up pressure were suggested. Also, the strength of hardened concrete as well as the filled state were proven to be acceptable ranges.

Currently, high strength steel is not used for steel bridges in Korea, except for the SM570 high strength steel in very isolated cases. The study aimed to promote the active adaptation of high strength steel for long-span steel bridges. Thus, the fatigue behavior of SM570 and POSTEN80 high strength steel was investigated. For the experimental study, the butt welded joints samples were manufactured. Likewise, regular amplitude tensile fatigue tests were conducted. Test results, e.g., location of fatigue cracks and their propagation were compared with the findings of other researchers. After analyzing the effects of fatigue strength, e.g., static tensile strength and plate thickness of base metal, basic data for fatigue design criteria of SM570 and POSTEN80 high strength steel were presented.
