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... Learn More

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.... Learn More

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... Learn More

Bridge Design – Loads and Load Combinations Properly identifying bridge loading is fundamental to the design of each component. Bridge design is iterative in the sense that member sizes are a function of loads and loads are a function of member sizes. It is, therefore, necessary to begin by... Learn More

Stormwater BMP Design Guide Best Management Practices can be designed to meet a wide range of goals and objectives. These can range from a single parameter approach such as flood control or pollutant removal, which is typical in older developed watersheds, to multiple parameter ecological sustainability of receiving systems,...

Stormwater BMPs for Vegetative Biofilters Historically vegetative biofilters, such as grass swales, were used primarily for stormwater conveyance (Ree, 1949, Chow, 1959 and Temple, 1987). However with the passage of the Clean Water Act, and the focus on water quality management of urban runoff, the potential for the application... Learn More
