چکیده
In the current study, experiments were carried out to investigate structural performance of reinforced concrete (RC) beams with a self-healing cover zone. The zone consists 1.5-cm-thick layer bacteria-embedded strain hardening cementitious composite (SHCC) for combination crack width control and healing. aim is bring together two emerging technologies (i.e., strain-hardening) that show great potential realizing highly efficient structures. RC beam without was also prepared as specimen comparison purposes. experimental program includes loading failure in four-point bending configuration sawing segments pattern analysis Results selfhealing exhibited 45-60% improvement capacity. patterns hybrid largely modified. While reference formed only few major cracks, around 40 fine cracks constant moment region an average smaller than 0.2 mm even at maximum load. By having improved cracking behavior enhanced capacity, it expected will possess extended service life expense minimal additional cost.

High Performance Reinforced Concrete Beams made with Sandstone Reactive Aggregates
An investigation on the flexural behaviour of reinforced high performance concrete (HPC) has been conducted. Crushed sandstone known as reactive aggregate was used for both fine and coarse aggregates. In addition, mineral admixtures such as silica fume and fly ash combined with superplasticiser was used. The beams were made with concrete having compressive strength in the range of 74 88 N/mm 2 ...
متن کاملCracking Resistance of Reinforced SFRFLC Superposed Beams with Partial Ordinary Concrete in Compression Zone
Abstract: A new reinforced SFRFLC (abbr. steel fiber reinforced full-lightweight concrete) superposed beam was proposed to sufficiently utilize the good peculiarities of ordinary concrete in compression and SFRFLC in tension, and reduce its self-weight. Experimental study was carried out on the flexural behaviors of reinforced SFRFLC superposed beams compared with reinforced concrete beams and ...
متن کاملReliability evaluation of reinforced concrete beams
The purpose of this paper is to evaluate the time-invariant reliability of reinforced concrete beams designed under the provisions of the ACI Building Code. A wide range of practical design situations is considered. The beams are subjected to bending, shear, and torsion. The interaction between shear and torsion is considered via an elliptical failure surface defined in the shear-torsion stress...
