In this study, the effect of deep excavation on the seismic response of RC moment resisting building systems has been studied. Deep excavation can cause significant changes in the stress and strain levels of soil environment and also changes in the propagation of seismic waves. This leads to permanent displacements in the foundation system. In this study, three RC building systems, i.e. 5, 10, ...

Strengthening of reinforced concrete (RC) beams with Self-compacting (SCC) jacketing galvanized welded steel wire mesh (SWM) has been an important area study so far. Increasing the mechanical characteristics and structures to maintain required service life load capacity any structure is exciting area. In this research, a Finite Element (FE) investigation conducted on series that were previously...

The use of fiber reinforced polymer (FRP) for flexural strengthening concrete (RC) beams has become a popular technique. Significant amount work is available on the short-term behavior RC strengthened with near-surface mounted (NSM) However, their time-dependent behavior, specifically under high service temperature, not yet been addressed. This paper presents an experimental to evaluate NSM car...

seismic performance and loss assessment studies for stock of buildings are generally based on representative models due to extremely large number of vulnerable buildings. the main problem is the proper reflection of the building stock characteristics well enough by limited number of representative models. this study aims to provide statistical information of structural parameters of turkish bui...

Corrosion is one of the major problems affecting the durability of reinforced concrete (RC) structures. This paper investigates the effect of rebar corrosion on the performance of reinforced self-consolidating concrete (SCC) members and the effectiveness of repair. A control RC member, which has no corrosion problem, was prepared to compare against corroded and repaired members. A number of rei...

The use of externally bonded Steel-Reinforced Polymer (SRP) and Steel Reinforced Grout (SRG) composites is a promising new technology for increasing the flexural and shear capacities of reinforced concrete (RC) members. The reinforcement system in these composites is a sheet made up of unidirectional cords consisting of tightly wound ultra high strength steel wires. The reinforcement can be mol...

The purpose of this study is to evaluate, through a nonlinear Finite Element (FE) analysis, the structural behavior of Reinforced Concrete (RC) beams externally strengthened by using Steel Reinforced Grout (SRG) and Steel Reinforced Polymer (SRP) systems. The parameters taken into account were the external strengthening configuration, with or without U-wrap end anchorages, as well as the streng...

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 bridg...

Numerical simulation models capable of predicting the nonlinear flexural behavior continuous reinforced concrete (RC) beams with corroded reinforcement were developed. Laboratory tests conducted to validate predictions numerical models. A parametric study was carried out examine effect varying location and severity corrosion on RC beams. The load capacity decreased linearly an increase in corro...

This study investigated the relationship between acoustic emission (AE) signals parameter sequence fractal characteristics and damage evolution information of corroded reinforced concrete (RC) beams under four-point bending. Strength deterioration behavior AE data can be obtained by coupling bending test monitoring. The results show that ringing counts uncorroded had prominent characteristics. ...
