Wind Loads For Petrochemical And Other Industrial Facilities

Wind Loads for Petrochemical and Other Industrial Facilities

Petrochemical and other industrial facilities are often exposed to high wind loads due to their location, geometry, and function. These facilities typically have complex structures that are not covered by the standard codes and standards for wind load design. Therefore, engineers need to use state-of-the-practice guidelines and methods to compute the wind-induced forces on these facilities and ensure their safety and performance.

This article provides an overview of the main aspects of wind load design for petrochemical and other industrial facilities, based on the ASCE report Wind Load Design for Petrochemical and Other Industrial Facilities. The report is a revised edition of the previous ASCE report Wind Loads for Petrochemical and Other Industrial Facilities, which was published in 2011. The report covers the following topics:

Fundamental wind engineering, general aerodynamics, and design considerations for nonbuilding structures.

Analytical determination of wind loads using the ASCE 7 standard and other methods.

Wind tunnel testing and computational fluid dynamic approaches to determining wind loads.

Alternate methods for determining aerodynamic force coefficients and load combinations.

Uncertainty associated with wind loads and how to account for it in design.

Wind loads for open frame structures, such as pipe racks, flare stacks, cooling towers, etc.

Special wind loading requirements for liquefied natural gas (LNG) facilities, such as storage tanks, vaporizers, piping, etc.

Examples of how to apply the recommended guidelines for determining wind loads on various types of industrial structures.

The report is intended to be a summary of current engineering knowledge and design practice, and present guidelines for the design of petrochemical facilities. It represents a consensus opinion of task committee members active in its development. The report is aimed at engineers familiar with design of industrial type structures, but it is not a substitute for professional judgment or experience. The report also does not provide detailed design procedures or specifications, but rather references other sources that can be consulted for more information.

The report is available for purchase from the ASCE bookstore or the ASCE library. It is also accessible online through some academic institutions or libraries. The report is a valuable resource for engineers involved in the design of petrochemical and other industrial facilities that are subject to wind loads.
