Reinforced Concrete Bridge Course

Lesson 1 • Steel Reinforcement Characteristics

Examines yield strength, ductility, and bond properties of reinforcing steel. Links material behaviour to load transfer mechanisms in concrete members.

Lesson 2 • Composite Behaviour of RC Sections

Analyses how concrete and steel interact under load through bond and compatibility. Establishes the transformed section concept used in flexural analysis.

Lesson 3 • Concrete Material Properties

Covers compressive strength, modulus of elasticity, and creep of concrete. Provides the material baseline required for all subsequent structural calculations.

Lesson 1 • Dead and Superimposed Dead Loads

Defines permanent gravity loads from structural self-weight and non-structural elements. Establishes accurate load takeoff procedures for bridge components.

Lesson 2 • Environmental and Other Loads

Covers wind, thermal, seismic, and braking forces on bridge structures. Ensures all non-traffic load sources are identified and quantified.

Lesson 3 • Vehicular Live Load Models

Presents standard truck, tandem, and lane load configurations for highway bridges. Teaches positioning of loads to produce maximum force effects.

Lesson 1 • Moment Envelope and Cutoff Points

Constructs bending moment envelopes from moving loads to locate peak demands. Determines safe bar cutoff and bend-up locations along the beam span.

Lesson 2 • T-Beam and Effective Flange Width

Extends rectangular beam theory to composite deck-girder T-sections. Determines effective flange width for accurate moment capacity calculation.

Lesson 3 • Reinforcement Detailing for Flexure

Translates calculated steel areas into practical bar arrangements and spacing. Addresses cover, bundling, and constructability constraints for bridge beams.

Lesson 4 • Flexural Strength Theory

Derives nominal moment capacity using the equivalent rectangular stress block. Connects material properties and section geometry to usable moment resistance.

Lesson 1 • Torsion Design in Bridge Members

Addresses compatibility and equilibrium torsion in curved and skewed bridges. Designs closed stirrups and longitudinal steel for combined shear-torsion loading.

Lesson 2 • Modified Compression Field Theory

Introduces MCFT as the rational basis for shear design in variable-depth members. Enables accurate shear capacity prediction for non-standard bridge sections.

Lesson 3 • Interface Shear and Horizontal Shear

Designs shear connectors at the deck-girder interface for composite action. Applies shear friction theory to construction joints and precast interfaces.

Lesson 4 • Shear Behaviour in RC Members

Explains diagonal tension cracking, shear transfer mechanisms, and failure modes. Provides the physical basis for all shear design procedures.

Lesson 1 • Deck Durability and Waterproofing

Addresses chloride ingress, cover requirements, and protective systems for bridge decks. Links durability measures to extended service life in aggressive environments.

Lesson 2 • Deck Structural Systems

Classifies deck types including cast-in-place slabs, precast panels, and voided slabs. Establishes the structural model appropriate for each deck configuration.

Lesson 3 • Empirical and Strip Method Design

Applies the empirical design method and equivalent strip method to deck slabs. Compares assumptions and applicability limits of each approach.

Lesson 4 • Punching Shear in Bridge Decks

Evaluates punching shear capacity around concentrated wheel loads on deck slabs. Determines whether shear reinforcement or increased thickness is required.

Lesson 1 • Pile Foundations for Bridge Substructures

Designs pile caps and selects pile types for axial and lateral load transfer. Connects pile group behaviour to pier and abutment structural demands.

Lesson 2 • Abutment Types and Earth Pressure

Classifies stub, seat, and integral abutments and quantifies active and passive earth pressures. Establishes the lateral load demands for abutment wall design.

Lesson 3 • Pier Types and Structural Behaviour

Surveys solid wall, hammerhead, multi-column, and hollow box pier configurations. Identifies the governing load path and failure mode for each pier type.

Lesson 4 • Column Design Under Combined Loading

Constructs interaction diagrams for RC columns under axial force and biaxial bending. Verifies column adequacy for all governing load combinations.

Lesson 1 • Shear Design for Prestressed Members

Applies web-shear and flexure-shear cracking models to prestressed bridge girders. Designs vertical and inclined stirrups for combined shear and prestress effects.

Lesson 2 • Continuity and Spliced Girder Systems

Converts simply supported prestressed girders to continuous systems for improved efficiency. Addresses secondary moments and splice connection design.

Lesson 3 • Prestress Loss Calculations

Quantifies elastic shortening, creep, shrinkage, and relaxation losses in prestressed girders. Accurate loss estimation is essential for serviceability and strength checks.

Lesson 4 • Flexural Design of Prestressed Girders

Checks stresses at transfer and service and verifies nominal flexural strength at ultimate. Integrates prestressed and mild steel contributions to moment capacity.

Lesson 1 • Rehabilitation Planning and Prioritization

Develops bridge management strategies using condition data and life-cycle cost analysis. Prioritises interventions across a bridge inventory for maximum benefit.

Lesson 2 • Bridge Inspection Methods

Covers routine, in-depth, and fracture-critical inspection procedures for RC bridges. Establishes systematic condition documentation as the basis for evaluation.

Lesson 3 • Deterioration Mechanisms in RC Bridges

Identifies corrosion, alkali-silica reaction, freeze-thaw damage, and fatigue cracking. Links deterioration patterns to root causes for accurate repair targeting.

Lesson 4 • Repair and Strengthening Techniques

Designs concrete patching, FRP wrapping, external post-tensioning, and section enlargement repairs. Matches repair method to deficiency type and structural demand.
