Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. But ASCE 7 indicates ultimate strength level forces for seismic load. Whether or not you can use Simplified Method for load calculation is completely unrelated to the question of whether or not it is enclosed.

I would agree with you. As an end note, the code recommends using 0. Click the radio button for decimal and then the coordinates auto-populate in the decimal location. Its an actual building I’m working on at the moment. This suggests that the snow load is transient in terms of the logic in the code.

Back solving for T results in a return period of approximately years. Promoting, selling, recruiting, coursework and thesis posting is forbidden. I also want to check here before going off and telling the intstuctor he’s wrong.

Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. The Eng-Tips staff will aace this out and take appropriate action.

Back on the wind load issue, I believe it is helpful to think of the wind loads provided by ASCE in terms of their recurrence intervals rather than stamping them with a “service” or “ultimate” level.

It is assumed that the asec of this site have competency to understand how to calculate and apply design wind loads to structural models of buildings or other structures.


Hey everybody – launching off of what Dave just said – what do you consider “transient” loads in terms of the IBC? The material presented in the windspeed report should not be used or relied upon for any specific application without competent examination and verification of its accuracy, suitability and applicability by engineers or other licensed professionals.

Or alternatively, if you have some other design code that allows stress increases for wind, you’d use the calculated loads without the reduction factor. ASCE Wind Loads – definition for enclosed structure ajh1, I agree with your comments, especially the note about “ballooning”, that is exactly what I think is the most important part of the three requirements for “partially enclosed” structures.

This is based on bringing the 50 year map speeds down to 10 year speeds.

ASCE Wind Loads – definition for enclosed structure – ASCE (civil) Code Issues – Eng-Tips

I note that if one accepts the instructor’s definition for enclosed structures, your example and mine do not meet the requirements for open, do not meet the requirements for partially enclosed, and also do not meet the requirements for enclosed.

Register now while it’s still free! The definition specified in the course for enclosed buildings was slightly different from the one in ASCE That is the general rule for “enclosed”, however the wind-borne debris rules requirement for the simplified approach could mean that the building could be “enclosed”, but not qualify for the simplified approach.

Download Now White Paper: The ASCE commentary and your responses have been very helpful. I believe ASCE-7 also gives recommended load factors in the first part of the book- check if that helps any.


This doesn’t seem right. Register now while it’s still free! It’s easy to join and it’s free. At the end of the course, there was a quiz. It’s easy to join and it’s free. Thank you all for your contributions.

,oads Fc is the wind speed multiplier so to get the force multiplier you must square 0. Second, common sense wise, is that live load is not always there and is therefore transient. Note that the ASCE wind loads utilize a wind directionality factor Kd which are not to be utilized without using there load combinations. Transient by dictionary definition is “passing with time” or “remaining in a place only a brief time”. I may be the one who’s wrong here.

Therefore using a 1. The course outlined the use of the simplified method for analyzing wind loads. Here is wine instructor’s definition for Enclosed Buildings: First, code wise, is section Am I correct in this assessment, that they are in fact allowable stress level loads?

As demonstrated in the commentary, you can back calculate the return period for a certain load factor by plugging in the square root of the load factor as Fc and solving for T. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. They only reduce wind or earthquake when applied with other loads. WillisV – sounds right to me.

So you can either use the equations from Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.
