ACI 341.4R-16 PDF Download

The ACI 341.4R-16 standard is a comprehensive document that outlines the analysis, modeling, and design practices for concrete bridges subjected to strong earthquakes. It is specifically aimed at practicing engineers and serves as a supplement to existing guidelines and codes such as those from AASHTO and Caltrans.

The standard provides a summary of the procedures and philosophies found in these codes and guidelines, discussing both linear and nonlinear seismic analysis methods. It emphasizes important modeling considerations for various bridge elements, including curved girders and skewed abutments. This ensures that engineers have the necessary tools to accurately analyze and design these unique structural components in seismic events.

Additionally, the report covers general seismic-resistant design and construction considerations for concrete bridges. This includes information on seismic isolation, a technique used to enhance the bridge's ability to withstand earthquakes. By providing analysis and design considerations specific to bridges with seismic isolation, the standard enables engineers to effectively incorporate this technique into their seismic design strategies.
