Bridge Design – Deep Foundations
Bridge Design – Deep Foundations Pile/shaft foundations can be an economical/necessary alternative to spread footings. A pile is defined as a slender deep foundation unit, entirely or partially embedded in the ground and installed by driving, vibration, or other method. A drilled shaft is defined as a foundation unit, entirely or partially embedded in the…
Bridge Design – Shallow Foundations
Bridge Design – Shallow Foundations Shallow foundations, also known as(spread footings, are advantageous to pile foundations considering lower cost, easier construction, and fewer environmental constraints. However, weak soil and seismic considerations may limit use of spread footings and impact the foundation type selection.In general, size of the spread footing is determined based on bearing resistance…
Bridge Design – Concrete Columns
Bridge Design – Concrete Columns Columns are structural elements that support the superstructure, transfer vertical loads from superstructure to foundation, and resist the lateral loads acting on the bridge due to seismic and various service loads. This course presents an overview of concrete column design. It discusses design loads and design criteria including the three…
Bridge Design – Concrete Bent Caps
Bridge Design – Concrete Bent Caps A bent consisting of columns and a bent cap beam is an intermediate support between bridge spans that transfers and resists vertical loads and lateral loads such as earthquake and wind from the superstructure to the foundation. The bent cap beam supports the longitudinal girders and transfers the loads…
Bridge Design – Steel Plate Girders
Bridge Design – Steel Plate Girders Girder bridges are structurally the simplest and the most commonly used on short to medium span bridges. Steel I-section is the simplest and most effective solid section for resisting bending and shear. In this course straight composite steel-concrete plate girder bridges are discussed. Design considerations for span and framing…
Bridge Design – Structural Modeling and Analysis
Bridge Design – Structural Modeling and Analysis Structural analysis is a process to analyze a structural system to predict its responses and behaviors by using physical laws and mathematical equations. The main objective of structural analysis is to determine internal forces, stresses and deformations of structures under various load effects. This course summarizes the guidelines…
