이 연구에서는 전단연결재의 종류를 변수로 더블리브유닛 깊은 데크플레이트 슬래브의 휨 실험을 수행하였으며, 실험결과를 기반으로 비선형유한요소해석을 통하여 춤이 깊은 데크플레이트와 콘크리트 사이의 합성도를 평가하였다. 그 결과, 전단 연결재가 설치되어 있는 경우 휨 강성 및 강도가 크게 향상되는 것으로 나타났다.

In this study, a numerical research has been conducted to investigate the fire resistance performance of prestressed hollow-core slabs, in which the number of prestressing strands and the load ratio were set as the analysis parameters. Based on the numerical simulation results, the temperature distribution and deflection according to the fire duration time were analyzed in detail.

In this study, an experimental research was conducted to investigate the effective compressive strengths of slab-column connections with different strengths. From the test results, it was found that the effective compressive strengths of the interior columns completely restrained by slab were similar to the compressive strengths of the columns.

In this study, the flexural tests were performed to investigate the flexural performance of prestressed hybrid wide flange (PHWF) beams. The main test variable was the shear stud on the top steel flange for composite action with the topping slab. All the specimens had the flexural strengths exceeding their design strengths. The test results also indicate that the PHWF beams had experienced fully composite behavior with high ductility, regardless of the existence of shear studs.
