Designing Walkable Urban Thoroughfares
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…
Bridge Design – Seismic Design of Concrete Bridges
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…
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…
