Reliability-based geotechnical design in 2014 Canadian Highway Bridge Design Code

Performance based seismic assessment of bridges designed according to Canadian Highway Bridge Design Code

Recent research efforts have focused on the development of performance based seismic design methodologies for structures. However, the seismic design rules prescribed in the current Canadian Highway Bridge Design Code (CHBDC) is based largely on force based design principles. Although a set of performance requirements (performance objectives) for different return period earthquake events have b...

Towards reliability-based design for geotechnical engineering

This paper presents an overview of the evolution in structural and geotechnical design practice over the past half a decade or so in relation to how uncertainties are dealt with. For the general reader who is encountering reliability-based design (RBD) for the first time, this would provide a valuable historical perspective of our present status and important outstanding issues that remain to b...

Design and Reliability Based Optimization of a 2d Arch Bridge

The aim of this work is to design and optimize a 2D Arch Bridge with reliability based optimization concept that is commonly used in transportation. After the arch bridge is modeled according to its original layout, the formulation of reliability-based optimization and other optimization techniques used in the work are presented. Then the bridge is optimized using various optimization methods u...

Robust Geotechnical Design – A New Design Perspective

System reliability-based geotechnical design of braced excavations in soft clays

This paper presents a preliminary study on the system reliability for the geotechnical design of braced excavations in soft clays. In this system reliability geotechnical analysis, both ultimate limit state (ULS) and serviceability limit state (SLS) are considered. Herein, the ULS failure refers to the basal heave failure, while the SLS failure refers to failures sue to excessive ground-surface...
