fiber reinforced polymers (frp) have widely used for the purposes of enhances strength and ductility of concrete columns. proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with frp. in this paper, the influence of frp thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...
Synopsis: The effects of thermal loads on the structural performance of FRP reinforced concrete elements are analyzed in this paper. The difference in transverse coefficient of thermal expansion (CTE) between FRP and concrete causes the presence of tensile stresses within the concrete and, eventually, the formation of cracks when the temperature increases. As part of an inter-university experim...
MATHCAD is a sophisticated computation and presentation tool, which is versatile, easy to use, and accessible. It holds strong potential as a learning aid for education and training. This article demonstrates the use of MATHCAD to supplement and enhance traditional teaching and learning methods both inside and outside the classroom. The paper focuses on the topic of reinforced concrete column d...
External prestressing has become a primary method for strengthening existing concrete beam and has been increasingly used in the construction of newly erected ones, particularly railroad bridges in recent years. In order to evaluate the effect of this method, the static and dynamic behavior of a T-frame beam reinforced by external prestressed strengthened concrete beam was analyzed by 3D finite...
The experimental study deals with Hybrid fibre reinforced concrete with the use of (Polypropylene and Recycled polyethylene terephthalate RPET). The M40 grade concrete used was designed by using IS10262-2009 code. The steel fibre and synthetic fibre were added at the volume fractions up to 0.5%. Test results showed that the fibres, when used in a hybrid form, could result in superior composite ...
Experimental studies on basalt fiber have been performed in China and abroad. Specifically, the compressive properties, flexural properties, splitting tensile properties and impact test behavior of chopped basalt fiber-reinforced concrete have been investigated. In addition, the effects of the mixing amount of fibers on the mechanical properties of C30 concrete were scrutinized, and the best mi...
Current approach for designing of reinforced concrete members is based on the load and resistance factor. However the load and resistance parameters are random variables, the constant values have been designated for them in the designing procedure. Assuming these factors as the constants, will be led to the unsafe and uneconomical designs. Safe designing of structures requires appropriate recog...
High Strength Concrete Incorporating Ground Granulated Blast Furnace Slag and Steel Fibres: A Review
This paper describes a review of the potential use of High Strength Incorporating Ground Granulated Blast Furnace Slag and Steel Fiber Reinforced Concrete used in construction industry to improve the structural strength and reduce steel reinforcements requirements. Blast furnace slag (GGBS) has been used as a supplementary material along with the cement. It helps in increasing the durability an...
A large number of reinforced concrete structures subjected to chloride ions. Two basicapproaches for preventing corrosion of reinforcing steel embedded in concrete are: Increasing theconsolidation of concrete and using different coating on rebars. In present research steel rebarsare coated in different ways: a) 40 µm of zinc electroplated on steel rebar b) Zinc powder withepoxy paste (zinc rich...
1. Abstract This paper presents a discrete optimization of reinforced concrete structures based on an efficient combination of deterministic and stochastic optimization strategies. The deterministic optimization algorithm is used for the detailing of a reinforced concrete crosssection for a given combination of internal forces. The multi-objective stochastic optimization algorithm is then appli...
