Program Outcomes

You can find bridges everywhere in the world. They are the structures built over obstacles to provide a passage for traveling. They have become the essential parts of the cities and new bridges are continuously built to make the transportation easier and effective. From the stepping stones that were used centuries ago to the modern bridges that we use today, bridges have evolved a lot and they are of so many types. Bridges of today are constructed bigger and stronger than their previous counterparts. The rapid development of the cities triggers and makes the construction of bridges as high-demanding engineering projects. 

Some bridges are just simple whereas some are extremely complex. These differences depend on so many factors including the purpose, soil conditions, local conditions like the accessibility and availability of resources, environmental conditions, topography of the environment, etc., which determines the design of a bridge. It is the primary duty of the designer to understand the problem statement before moving on to design the structure. The designer should have prior knowledge on selecting the suitable type of bridge, span, material, structures, etc., 

This program is particularly designed to give you a solid understanding of bridges, and it covers the analysis and designing of various components of bridges. The program includes a number of courses which cover various topics of bridge designs accompanied by the projects where the learner can apply what one learnt during the course.

4. Bridge RCC & PSC Superstructure Design using LUSAS

1 Concrete design refresher and bridge form selection

This lecture will introduce the concrete as a construction material. Students are expected to have basic understanding of concrete design, but, the lecture will remind them about the theory and key design principles. The lecture will also cover how concrete is used in bridges showcasing different forms and real-life examples where they are applied. It will explain where this material is most effective and tell how to choose appropriate form for a given site.

2 Design of RCC solid Slabs

This lecture will build on concrete design basics by introducing the most basic form of concrete bridges – solid slab. The lecture will explain how moments and forces are distributed, introducing the principle of effective width. The students will learn how to analyse slabs using hand calculations, design aids (e.g. Pucher charts) and computer-based analysis. The lecture will cover bending and shear resistance calculations allowing students to derive a safe slab thickness and specify appropriate reinforcement. Other important considerations such as punching, deflection and cracking will be covered. As well as standalone slab bridges, the course will cover continuous multi-span slabs (e.g. transverse design of composite plate girder slabs) and cantilever slabs (e.g. box girder outriggers). The lecture will touch on design of skew slabs.

3Design of RCC voided slabs and introduction to grillage modelling

This lecture will develop from solid slab design introducing voided slabs. It will explain the analysis complexities introduced by inclusion of voids in the body of concrete and show how grillage modelling can be used to tackle them. Transverse distortional effects experienced by these types of cross section will also be covered. The students will learn how to design and detail voided slabs to tackle longitudinal bending and shear as well as transverse effects arising from distortion.

4 Design of RCC ribbed slabs

This lecture will continue the theme of cast-in-situ bridges and will talk about ribbed slabs. It will go through further examples of grillage modelling and how it can be applied to analyse these types of bridges. Other methods of analysis, such as shell and beam type models will be demonstrated, explaining where this may be beneficial. The students will learn how to design a concrete T-sections, selecting appropriate effective width. They will also learn about interface shear between rib and slab. Various details will be discussed, e.g. where a cross beam is necessary and how ribbed slabs are constructed.

5 Design PSC I Girders

Students will learn about the benefits of prestressing compared to mild reinforcement. Various types of prestressing will be discussed, covering the differences between pre-tensioning and post-tensioning, and between bonded and unbonded tendons. Unlike reinforced concrete bridges, the prestressed bridges are often governed by serviceability limit state rather than ultimate capacity. The students will learn how to use stress-based calculation in order to check the structure is safe. The principle of brittle fracture will be introduced, demonstrating several real-life examples where this had led to catastrophic failure. The students will learn how to check the structure is no prone to brittle failure and how to prevent this type of behavior. This lecture will begin the talking about long-term effects (creep, shrinkage and PT losses), priming the students for the later course content.

6 Design of PSC Box Girders

Building on the previous lecture the students will learn how to design and detail concrete box girders. Various types of structures will be covered, from U-beam type bridges to straight and tapering multi-span bridges. The lecture will also touch on application of box girders in cable-supported bridges. Effects of torsion and curvature will be discussed. The students will learn how to analyse these types of structures and consider the aforementioned effects. This lecture will begin the talking about construction stage analysis, priming the students for the later course content.

7 Introduction to strut and tie analysis and local effects

The students will learn why beam theory is not always applicable in concrete bridge design. After listening to this lecture, they will know how to identify D (discontinuity) regions and draw appropriate strut and tie arrangement to capture their behavior. They will then learn how to resolve a strut and tie model by hand and using a truss type computer analysis. This lecture will explain how there can be different strut and tie arrangement for the same problem and why some are better than others, giving examples of typical real-life problems and their most efficient solutions. This lecture will also touch on local effects such as bottlenecking, splitting and multiaxial compression.

8 Design of bridge details using S&T analysis

This lecture will continue the topic of struct and tie modelling and will dive into its application in bridge design. Classic bridge details will be shown, namely monolithic connections, half-joints, bearing regions, PT anchorages and stay-cable anchorages. Students will be demonstrated advanced uses of strut and tie modelling and how it can be applied in 3D.

9Portal frame bridges and integral bridges

This lecture will talk about integral bridges, their advantages and limitations. Typical problems concerning integral bridges will be discussed, such as ratcheting behind abutment and the need for close collaboration with geotechnical engineers. Although soil-structure interaction is a large topic worthy of a separate course, its implications on design will be clearly explained. The students will learn how to design a basic portal frame bridge and how to detail the abutments of a longer span concrete bridge. Temperature and differential temperature loads should be discussed in this presentation.

10 Composite plate girders and trusses

This lecture will focus on application of concrete in composite bridges. The student will apply earlier skill of grillage analysis and slab design and apply them to composite structures. They will learn how to calculate elastic and plastic section properties using effective Young's modulus method. They will be demonstrated how to perform basic structural checks of a composite plate girder and truss bridges including design of shear studs. Advanced topics such as buckling and construction stage analysis will be mentioned, but not covered in depth, as these topics should be subject of the steel bridge superstructure course.

11 Long terms effects

This lecture will focus on the long-terms effects, namely creep, shrinkage and loss of prestress, which had been introduced earlier in the lecture series. They will learn how to calculate long-term section properties. Examples where creep and shrinkage cause parasitic effects will be demonstrated, e.g. moments in continuous prestressed bridges and composite girders. This part will also discuss the movement ranges and calculations related to the expansion joint specification. Movement and friction at bearings will also be mentioned.

12Construction Stage Analysis

This lecture will demonstrate various ways in which concrete structures can be constructed, e.g. cast-in-situ, launching and balanced cantilever construction. The students will learn that construction sequence can often govern design and that structures should always be checked in their temporary conditions.
