The Experimental Study on the Behavior of Precast Girder-Infilled Steel Tube Column joint |
| Abstract |
This study is to examine the usefulness in using precast girder-infilled steel tube column through the analysis of the test results. In this study, based on the followed variables, The concrete strength in the joint connection, The number of hoop reinforcement in the joint connection,The anchor method of the main bar of the precast girder, The shape of precast girder-infilled steel tube column joint.:We estimate the ultimate load, stiffness-reduction ratio, and deflection-ductility ratio, and so on. Therefore we investigate the facility of construction, stability of structure and offer the fundamental data to the new hybrid structural system, with precast girder-infilled steel tube column.From the test, We have the following results. The first crack was occurred vertically at beam-column joint. Maximum strengthof specimens was mainly decided on concrete strength of beam-column joints, and ductility of specimens was decided on the number of hoops in beam-column joint. By raising strength of concrete and incresing number of hoops in beam-column joint, it becomes clear to take similar structure capacity to monolithis structures. |
