چکیده
Most of the existing engineering structures were built in last century and have been service for decades. However, environmental degradation may lead to a reduction structural performance life. The mechanical property data full-scale structures, such as bridges, are essential health monitoring. For this purpose, five (half) reinforced concrete (RC) T-beams removed from retired 31-year-old bridge subjected destructive testing. Two loading points employed, flexural shear capacities studied. results showed that all beams held high load (exceeding 1400 kN). two test exhibited ductility, three failed. In addition, cracks reopened when exceeded 200 kN, while it was 300 kN beams. load-carrying capacity experimental values compared with ones calculated according Chinese code JTG-3362-2018; shown still maintained degree safety margins despite initial defects. expected provide reference assessment in-service RC bridges.

Flexural Behavior of Reinforced HPFRCC Beams
High Performance Fiber Reinforced Cementitious Composite (HPFRCC) materials exhibit strain hardening behavior with multiple cracking under tensile loading. In this paper, experimental and parametric studies are performed to assess the influence of using HPFRCC material instead of normal concrete in reinforced concrete beams. After calibrating the experimental results, the analytical results inc...
متن کاملExperimental Investigation on Shear Cracking Behavior in Reinforced Concrete Beams with Shear Reinforcement
This paper presents an experimental investigation to clarify shear cracking behavior of reinforced concrete beams. The effects of the various influential parameters on the spacing between shear cracks and the relationship between shear crack width and stirrup strain at the intersection with shear cracks were carefully investigated. It was found that shear crack width proportionally increases wi...
متن کاملHysteretic Behavior of Conventionally Reinforced Concrete Coupling Beams in Reinforced Concrete Coupled Shear Wall
This paper presents the experimental results of four full-scale coupling beams in which only horizontal reinforcements are placed, without diagonal reinforcements, with the aim to develop reinforcement details for coupling beams used in connecting side walls in a wall-slab structural system. Each coupling beam specimen was designed according to the deep-beam design procedure that does not use d...
متن کاملExperimental Study on Full-Scale Beams Made by Reinforced Alkali Activated Concrete Undergoing Flexure
Alkali Activated Concrete (AAC) is an alternative kind of concrete that uses fly ash as a total replacement of Portland cement. Fly ash combined with alkaline solution and cured at high temperature reacts to form a binder. Four point bending tests on two full scale beams made with AAC are described in this paper. Companion small material specimens were also casted with the aim of properly chara...
