Two-days Technical Workshop, 2016

Bridge Design, Analysis and Construction University of Cape Town, Department of Civil Engineering

Johannesburg (venue tbc): February, 15 - 16 08:00 – 17:00

Durban (venue tbc) February, 18 - 19 08:00 – 17:00

Cape Town (venue tbc): February, 22 - 23 08:00 – 17:00

Introduction

This workshop covers various practical aspects of bridge design, analysis and construction

including conceptual design, live loading, and the design of structural systems and components.

The emphasis will be on highway, railway and pedestrian bridges in reinforced and prestressed

concrete. In addition, principles of steel bridge design will be covered. The workshop will focus

on application of engineering concepts and practical design approaches. A number of design

examples (conceptual design and detailed structural design) for various common bridge types

will be presented.

In the lectures, fundamental principles will be discussed, but the focus will rest on practical

design examples and presentation of step-by-step approaches for the identification of various

conceptual and structural design solutions. Delegates will be given practical “hands-on”

information on how to apply the fundamental design concepts in various real-life situations.

Topics and Scope

- Conceptual design of bridges

o Design objective and design basis; Procedure of conceptual design; Load bearing

systems and their using conditions (type selection); Pre-stressing of bridges

o Worked examples of conceptual design (from site conditions to the selection of

suitable bridge types; estimation of span lengths and cross-sectional dimensions, etc.)

- Preliminary structural analysis of bridges

o Load models in Europe and South Africa; highway-, railway-, pedestrian-bridges

o Worked examples (bridge loading; bending moments and shear forces; critical cross-

sections, etc.)

- Structural design

o Selection of cross-sectional dimensions; prestressing systems and tendon layout;

prestress forces and prestress losses

- Construction technology (choice of suitable methods; practical considerations; cost

comparisons)

Presenter: Professor Steffen Marx

Professor Marx is a renowned bridge design engineer from

Germany and has taught bridge design at various universities in

Germany and the USA. He has been working for 10 years as a

consulting bridge design engineer and was appointed Professor

at the University of Dresden, Germany, in 2007. From 2010 to

1011, he was Visiting Professor at the University of California at

San Diego, USA. In June 2011, he was appointed Professor and

Chair of the Institute of Concrete Structures at the Leibniz

University Hannover, Germany. Since 2007, Professor Marx has

been the Executive Secretary of Advisory Board of Bridge Design

of the Deutsche Bahn (German Railway).

His experience in bridge engineering links mainly to reinforced

and prestressed concrete bridges (road bridges as well as

railway bridges). He is the co-owner of one of the leading bridge

engineering consultancies in Germany (www.marxkrontal.com).

During the last 5 years he was responsible for the design of two of the largest high-speed

railway bridges in Germany (the Unstruttal Bridge with a total length of 2,6 km and the

Scherkondetal Bridge with a length of 570 m). For the Scherkondetal Bridge, his design team

won the prestigious German Bridge Design Price (Deutscher Brückenbaupreis) in 2011.

Professor Marx has visited South Africa numerous time and is a Research Associate at the

University of Cape Town, Department of Civil Engineering.
