“…In particular, as contemporary structures are being constructed higher and larger due to the development of high strength materials with the continued advances in construction technologies, various composite structural systems have been developed and proposed that can realize the long-span structures and reduce floor heights (Ayyub et al 1990(Ayyub et al , 1992aKim et al 2002Kim et al , 2009. Figure 1 shows various composite structural members developed from previous researches (Azizinamini et al 2004;Bae and Lee 2007;Abbas et al 2007;Heo et al 2007;Hong et al 2010a, b, c, d;Kim et al , 2013Oh et al 2012Oh et al , 2015Lee et al 2015), among which the prestressed composite systems can lead to enhance the strength, ductility, and serviceability of the structural members, utilizing the prestressing force introduced to the concrete. Although many other steelconcrete composite girder systems have been developed, as shown in Fig.…”

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 and designed to effectively resist external loads considering the actual construction sequences. Two specimens with and without shear connectors were fabricated and tested to examine the effect of the shear connectors for achieving the fully-composite behaviors between a cast-in-place (CIP) concrete and the prefabricated prestressed steel-concrete composite girder. The test results showed that sufficient flexural strengths and deformation capacities can be obtained in both types of PHWF composite girders with and without shear connectors. To reflect the actual construction stages of the proposed PHWF composite girder, nonlinear flexural analyses were proposed considering the prestress effect and segmental effect before and after composite with the CIP concrete, respectively. The observed and analysis results of strain behaviors of the PHWF girder specimens were also compared and discussed in detail.
