Wind Load CFD Modeling for Rooftop Elements Compared to ASCE 7

2018-02-20T11:28:46+00:00

  Wind Load Comparison between CFD and ASCE 7 for Rooftop shapes Welcome back to our blog series on the phenomenon called Wind Load CFD Modeling and how it affects civil and mechanical engineers.  Wind Load is the force that blowing wind exerts on any device or structure that extends above ground level.  After an initial introduction to the factors that affect wind load on an object, I compared three different sets of wind load calculation methods using three simple objects, hypothetically placed on a 100-foot-tall building.  Starting with generic drag equation for the first equation, added two modification coefficients called "gust factor" and "exposure coefficient" for the second equation.    I used the model for rooftop objects for the [...]

Comparing Wind Load Calculation Methods

2018-02-21T15:26:59+00:00

Wind Load Calculation Wind Load Calculation is an overview of the force that blowing wind exerts on a tall object.  A number of factors that influence the actual wind load on a real building, include the surrounding terrain, nearby structures,  trees, and typical weather patterns for the area.  Comparing wind load calculations are most complicated . Calculations try to account for as many of these external factors as possible, to the point where the wind load section in American Society for Civil Engineer’s ASCE 7 standard, spans five chapters and over 100 pages. Fig 1: Wind load calculation example structures ASCE 7's Applications Comparing one of ASCE 7’s Applications with the two equations [...]

Wind Load Calculations and Modeling

2018-02-20T12:26:27+00:00

 Part 1 of our Wind Load Series “Wind load” is a calculated value representing the total force on a structure or object cause by pressure from wind moving over it.  In this blog series, we will discuss different methods for wind load calculations, the factors that influence its magnitude, and the effects a high wind load can have on a structure.  Wind load is most commonly addressed by civil and structural engineers when designing buildings, but mechanical engineers can encounter the effect when designing tall objects like cranes, telescoping communications masts or wind turbine towers. Wind Load Essentials As a force, wind load is the product of pressure distributed over an area (psf times ft2 or Pa times m2).  In [...]
