Breakage (Soil) Mechanics

Introduction
Critical state soil mechanics (CSSM) was originally developed for clays. For this application CSSM continues to provide the most elegant mathematical theory for capturing the physics of the material. In its simplicity, only five parameters are needed to describe a broad range of critical effects. However, when CSSM is adapted to model sand-agglomerates, models can no longer be accurately defined using five parameters. The CSSM theory requires fitting the slope of the isotropic-hardening compression ....etc

Corrosion Of Reinforcement In Hvfa Concrete

Introduction
Corrosion of reinforcements has been one of the major challenges that the civil engineers have been facing. Corrosion leads to the formation of rust which results in the spalling of concrete which in turn leads to the exposure of rebars to the aggressive environment. This will accelerate the ill effects and ultimately leads to the break down of the structure. Corrosion mainly occurs in areas of aggressive environment such as coastal regions. It is very important that corrosion of rein ....etc

Non-Linear Analysis and Design of Perforated Thin-walled Steel Strutures

Introduction
Perforated thin-walled steel structures are widely used, however, current design guidelines for them are limited to very few specific cases.
The seminar will try to describe a proposed method to develop new design guidelines for this kind of structures by using the Direct Strength Method (DSM) which is a fast and easy design method for cold-formed steel structures, with great potential for complex and optimized cross sections.

Based on the recently de ....etc

Seismic Behavior Of Isolated Bridges

Introduction
Bridges are lifeline structures. They act, as an important page link in surface transportation network and failure of bridges during a seismic event will seriously hamper the relief and rehabilitation work. There are many cases of damage of bridges in the past earthquakes all over the world. Due to their structural simplicity, bridges are particularly vulnerable to damage and even collapse when subjected to earthquakes. The fundamental period of vibration of a majority of bridges is in the ....etc

Analysis of soil classification using normalized piezocone parameters
Analysis of soil classification using normalized piezocone parameters

Introduction
The number of variables which influence cone tip resistance, penetration pore pressures, and CPT sleeve friction typically exceed the range of variables covered by databases of sites used for calibration of correlations for soil classification charts. Therefore, it is important to understand the mechanisms which influence piezocone parameters during the development of design recommendati ....etc

Study and Modeling of the Mechanical Behavior of Hexagonal Metals

Introduction
Hexagonal close-packed (hcp) metals deform plastically by a variety of slip and twinning modes. The relative contribution of these mechanisms depends strongly on the material studied and the conditions, such as temperature, under which the deformation is performed. This work further elucidates the complicated competition and interactions between twinning and slip deformation modes for two hcp materials, namely zirconium and magnesium. The model presented here to ....etc
