7 Corrosion of reinforcing steel in concrete can alter the interface between the steel and concrete and 8 thus affects the bond mechanism. This subsequently influences the behaviour of reinforced 9 concrete structures in terms of their safety and serviceability. The present paper attempts to 10 develop a numerical method that can simulate the behaviour of reinforced concrete walls subjected 11 ...
As part of a larger project to investigate the use of Fiber-Reinforced Polymer (FRP) materials in bridge construction, a short-span FRP-reinforced concrete bridge was installed in central Missouri. The Walters Street Bridge is a precast concrete panel bridge reinforced with both glass FRP (GFRP) and carbon FRP (CFRP) reinforcing bars. It was designed according to the American Concrete Institute...
: In the present paper, lessons are learnt from ant society so that humankind can optimize his engineering issues. As an example of such issues, a reinforced concrete retaining wall for which the application of optimization can reduce the costs involved is considered. Traditional design procedure for reinforced concrete retaining walls is unable to design an optimized wall unless a large trial ...
In recent years many research on composite beams with innovative shear transmission with composite dowels have been conducted and innovative composite constructions have been built. One of the common types of shear connection is the method of rolled girders encased in a concrete slab. The combination of such method and pcb (precast composite beam) technology is called pcb-W (precast composite b...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Many existing reinforced concrete structures were constructed with substandard characteristics. Low quality concrete, poor transverse reinforcement details and insufficient flexural strength are among the most common deficiencies. While substandard structures are in need of retrofitting, particularly in seismic areas, problems such as high costs and disturbance to occupants are major obstacles ...
There have been great developments in the area of civil engineering in the recent few decades and among these, construction and material innovation are quite prominent. Steel-concrete composite construction has emerged as one of the fastest methods of construction. Even though considerable research efforts on conventional reinforced concrete columns have been executed prior to now, concrete fil...
