The prestressing force is transferred to the concrete during the slack period of precast concrete structures fabrication. To contribute to a better understanding of the armor compliant behaviors during the mentioned process, a custom quasidistributed Bragg Grating optical fiber sensor system is designed, fabricated and embedded into a prestressed concrete prismatic beam. The experimental works,...

the present study focuses on the performance of precast concrete beam-column dowel connections subjected to cyclic loading by conducting experiments. in this study, one-third scale model of two types of precast and a monolithic beam-column connection were cast and tested under reverse cyclic loading. the precast connections considered for this study is a beam-column connection where beam is con...

a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...

Consideration of fiber configuration and the distance between light source or meter LTC specimen in previous studies is still limited. The incorporation plastic optical (POF) into concrete with configurations 5 ´ 6 grids investigated terms short wall panel application to study its intensity strength properties. light-transmitting (LTC) 300 mm wide 400 high 75 thick cast using self-compacting (S...

Abstract Post-tensioned precast concrete walls are an attractive research trend in structural engineering, which replaces cast-in-place earthquake-prone buildings. Precast use mild steel and high-strength post-tensioning for flexural resistance. Mild reinforcement yields tension compression, dissipating inelastic energy. Unbounded tendons used inside the wall to give self-centering capability, ...
