Due to the rapid industrialization taking place globally, the problems generated are acute shortage of construction material and increasing in productivity of wastes. The production and consumption of plastic and the rate at which solid plastic waste (SPW) are created have increased considerably. Plastics constitute 12.3% of total waste produced most of which is from discarded water bottles. Th...

The project aims to study tensile softening behavior of fiber reinforced concrete .Concrete is very much weak in tension but by addition of randomly oriented short crimped steel fibers will change the behavior from brittle to ductile. In the present work, the steel fibers were added at the volume fraction, being 0%, 0.5%, 1%, 1.5% to the normal strength concrete and high strength concrete. The ...

In this paper, the elastic-plastic analysis of cantilever beam and Reinforced Concrete (RC) column-Steel (S) connection are studied using Radial Basis Function- Finite Difference (RBF-FD) method. A direct method bilinear nodes is proposed to deal with instability caused by first derivative calculation in traditional RBF-FD Based on idea gradient projection method, improved further applied multi...

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 ...

Jacketing of reinforced concrete columns is a common and useful strengthening method. This method substantially improves mechanical properties of the column, such as flexural strength as well as shear and ductility. In this paper, the behavior of confined reinforced concrete columns are investigated. The results indicate that the method is more effective for slender columns in the region of the...

SPEAR 3 is an upgrade of the 18-cell SPEAR 2 storage ring to 3GeV beam energy, 18nm-radian emittance and up to 500mA circulating current. The existing arrangement of photon beam lines remains largely unchanged, but opportunities arise for additional ID and dipole radiation exit ports. For optimum beam stability, the entire tunnel floor will be excavated and replaced with reinforced concrete. Th...

It is observed that, reinforced concrete beams failed due to flexure but in case of deep beam failure occur due to shear. Deep beams may be defined as the beam where shear span to depth ratio less than 2. A number of researchers already proposed various approach to predict the ultimate strength of deep beams. In this study a newer approach is developed to calculate the ultimate shear strength o...

The method of damage analysis reinforced concrete columns based on the fiber element model is established by combining uniaxial constitutive and steel with beam–column model. quasi-static test shaking table are simulated analyzed, respectively. results show that can predict nonlinear mechanical behavior distribution good accuracy. Furthermore, effectively simulate evolution process columns, des...
