Components and Cladding Example
This article provides a Components and Cladding (C&C) example calculation for a typical building structure. We will first perform the calculations manually, and then show how the same calculations can be performed much easier using the MecaWind software. What is...
Fastest-Mile Wind Speed
Many times we have the difficult task of analyzing a structure that was designed long ago. In such cases, you may find that the wind speed used may appear significantly lower than the wind speed you would expect for that location using today's standards. In these...
ASCE 7 Wind on Stacks and Similar
This article will explain how to calculate wind loads per ASCE 7 on stacks/chimneys and similar structures. ASCE 7-16, Chapter 29 covers "Other Structures". This is a very broad section that covers a lot of different types of structures. Even if you don't design...
Wind Wizard
MecaWind has many features and options within the software, which can be both a blessing and a curse. It gives the user greater control over the results they obtain, but for the novice user it can be overwhelming to understand what is being requested with each...
How to Find Wind Pressure on Solar Panels
In this article we will investigate the procedure for calculating the design wind pressure on rooftop solar panels per ASCE 7-16 design code. I feel like the best way to describe this procedure is by working through an example, and that's just what we will do. For...
Base Reactions in MecaWind
There can be confusion from users on how to read and interpret the MecaWind Base Reactions that are provided by the MecaWind software program. There is a lot of data presented, and it can become overwhelming. This article is intended to help explain how MecaWind...
ASCE 7 Flexible Gust Factor
When I was a new Engineer my boss had his stack design questioned by a client. My boss responded "Sir, I will serve you tea on the downwind side of that stack on the windiest day of the year." That line (and disturbing image) has never left my mind. Designing tall...
One Click Components & Cladding
Would you like to be able to calculate all of your Components & Cladding (C&C) values with one Click? In this article that's what we are going to show you. Component and Cladding Summary: The normal way of analyzing C&C in MecaWind is to enter each...
