ASCE 7 has a method for calculating wind loads on rooftop Structures and equipment for buildings, and this article will describe that method. Fortunately, the method is relatively straight forward, not too complicated, and is covered in ASCE 7-16 Section 29.4.1What...
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...
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...
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...
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...
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...
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...
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...
It was Tom Cruise in "Top Gun" who once said, "I feel the need, the need for speed". I sometimes wonder if Tom Cruise is on the ASCE 7 committee, because it feels like they have the need to change the wind speed basis with every new release of ASCE 7. I'm not...
