ASCE 7-16 added a new option to address wind loads on a canopy attached to a building with a h <= 60 ft [18.3 m]. This new criteria for canopies is addressed in ASCE 7-16 Section 30.11, and since it is in Section 30, the canopy is classified as Components and...
ASCE 7 has multiple methods for calculating wind loads on a Parapet. In the context of a building design, a parapet is a low protective wall along the edge of a roof. It could be used to hide equipment on the roof and it can also serve as a barrier to provide some...
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...
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...
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...
