This paper presents an improved earth pressure method that considers the capacity of a wall toe to carry load predict connection loads GRS segmental walls constructed with cohesionless backfills on competent foundations. In this method, response surface model (RSM) lateral coefficient replaces Coulomb active coefficient. The parameters RSM were determined from numerical studies impacts restrain...

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...

Porosity is a result of a deficiency in the production process that could lead into the mechanical degradation of CFRP composite structures. Therefore, some checkpoints for determining its presence during part manufacturing have to be established, verifying that precise threshold values are not exceeded. Currently, porosity characterization is carried out by an indirect way using ultrasonic tec...

Carbon fiber reinforced polymers (CFRPs) have found wide-ranging applications in numerous industrial fields such as aerospace, automotive, and shipping industries due to their excellent mechanical properties that lead to enhanced functional performance. In this paper, an experimental study on edge trimming of CFRP was done with various cutting conditions and different geometry of tools such as ...

This paper describes a research program that was conducted in two phases to study the behavior of a high modulus CFRP system for strengthening steel structures. The first phase of the research consisted of an experimental program and finite element analysis to study the bond characteristics of the system. The findings indicate that a reverse tapered plate end detail can effectively increase the...

This work presents an optical non-contact technique to evaluate the fatigue damage state of CFRP structures measuring the irregularity factor of the surface. This factor includes information about surface topology and can be measured easily on field, by techniques such as optical perfilometers. The surface irregularity factor has been correlated with stiffness degradation, which is a well-accep...

The continual growth of network traffic rates leads to heavy packet processing overheads, and a typical solution is to partition traffic into multiple network processors for parallel processing especially in emerging software-defined networks. This paper is thus motivated to propose a robust dynamic network traffic partitioning scheme to defend against malicious attacks. After introducing the c...
