Precast Concrete - 2 - Example 2 - Live Load Distribution Factors for Bridges

Описание к видео Precast Concrete - 2 - Example 2 - Live Load Distribution Factors for Bridges

This example is in Module 2 of my Precast Concrete Design course (Codes and Loads). This example goes through how to find the live load distribution factors for a bridge with precast concrete girders using the AASHTO LRFD Bridge Design Specification (8th Edition). Distribution factors for moment and shear are found using AASHTO LRFD tables and using the lever rule for interior and exterior girders. Details are also provided for finding distribution factors for precast sections with decks already cast with the beam (e.g., NEXT D beams, decked bulb-tee girders).
