Bridge Design – Concrete Design Theory This course presents the fundamental concepts of concrete design theory applied in bridge design practice in California highway structures. Concrete is the most commonly used material in California highway structures, especially after the wide acceptance of prestressing technology in the 1950s. Nowadays, concrete bridges, prestressed or non-prestressed, account for...Learn More

Designing Walkable Urban Thoroughfares Traditionally, through thousands of years of human settlement, urban streets have performed multiple functions. Mobility was one of the functions, but economic and social functions were important as well. Retail and social transactions have occurred along most urban thoroughfares throughout history. It is only in the 20th century that streets were...Learn More

Bridge Design – Seismic Design of Concrete Bridges This course provides guidance on the seismic design of Ordinary Standard Concrete Bridges. It describes general seismic design considerations including pertinent formulae, interpretation of Caltrans SDC provisions, and a procedural flowchart for seismic design of concrete bridges. This course works through a seismic design example of a...Learn More

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...Learn More

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...Learn More
