“…Various types of external wall systems that comprise structural body, insulation layers, openings like doors and windows with various glazing types are used in high-rise residential buildings because dry light-weight members are advantageous compared to RC-based wet construction methods in terms of constructability [2,3]. Lightweight members, especially glass fiber reinforced concrete (GFRC) and cellulose fiber reinforced concrete (CFRC), are often utilized due to economics, constructability and texture.…”

“…Reinforced concrete (RC) bearing wall systems are often used to construct residential buildings rather than column-beam systems in terms of economic benefits [2][3][4]. However since the existing bearing wall system has limitations in vertical construction, the use of column-beam systems is on the rise, particularly for high-rise residential buildings [5][6][7].…”

“…In addition, the construction period could be substantially reduced while increasing the safety during the construction. In their previous studies, performed an analytical investigation of the structural behavior of steel–concrete composite beams based on the strain compatibility approach. Three specimens were loaded to failure to verify the reliability of the proposed strain compatibility method, and it was found that the flexural moment capacities obtained from analytical investigations were similar to those obtained from experimental investigations.…”

Summary Herein, the authors propose prestressed composite beams with steel sections at both ends of the precast beams in order to provide flexural strength against negative moments at both ends. This study extends the use of prestressed precast composite beams by understanding the instantaneous and time‐dependent losses of prestressed forces. This study also attempts to find out whether the currently available equations predicting instantaneous and time‐dependent losses of prestress can be used to predict the performance of prestressed precast composite beams. In this study, analytically calculated prestress losses of precast composite beams were compared with the loss of prestress observed during experiment to evaluate the eligibility of the proposed analytical approach and to calculate the losses of prestressing forces for precast composite beams. The influence of steel sections installed at both ends of the precast beams on the loss of prestress was also investigated to estimate prestress loss of the prestressed precast composite beams. The 20% loss was recommended for the instantaneous prestress loss for the precast composite beams, accounting for the contribution of T steel members of precast beams to the elastic contraction.

Abstract-A great deal of research is being carried out on dry and prefabricated construction methods with a precast composite structural system. This study investigates the joint behavior and calculates structural capacity of a Smart frame, which is a steel-reinforced concrete structural system developed by researchers in a structural experiment. The structural experiment discovered that flexural moment capacity improved by 46.8% in Smart columns compared to reinforced concrete columns. This study is expected to contribute to structural design.Index Terms-Joint, precast composite structural system, smart frame, strain compability, structural experiment joint.
