Service-Load Behavior of Precast/Prestressed Concrete

2018-5-1  This paper describes an experimental investigation on the use of recycled concrete aggregates (RCAs) as replacement for coarse natural aggregates (NAs) in precast/prestressed concrete structures. Specifically, sustained service load tests were conducted on 18 pretensioned beams with two different levels of RCA (50% and 100% by aggregate volume ...

Service and Ultimate Load Behavior of Precast-Prestressed

Since most precast concrete applications use prestressing, this research specifically investigates the effects of RCA on: (1) rate of concrete strength and stiffness gain; (2) strand bond strength; (3) prestress losses; and (4) service load and ultimate load behavior of precast-prestressed concrete beams.

Behavior of Precast Prestressed Concrete Segmental Beams

Abstract. The structural behavior of Segmental Precast Post-tensioned Reinforced Concrete (SPPRC) beams largely depends on the behavior of the joints that connect between the segments. In this research, series of static tests were carried out to investigate the behavior of full-scale SPPRC beams with different types of epoxy-glued joint ...

Behavior of Precast Prestressed Concrete Segmental Beams

The openings between the segments and crushing of the concrete compression region were the main reasons for the nonlinear behavior of segmental prestressed-concrete beams. Yuan et al. 2015 [6] found that different tendon ratios and different load types increased the external tendon stress and the width of joint openings, and also altered the ...
