Yes, you are absolutely correct, I am using the Aluminum Design Manual for the mullion members. This is when we add steel reinforcing to obtain greater heights for the mullion. I am assuming that the mullion will take all the stress before steel reinforcement will help the mullion and they work...
Hello Fellow Engineers,
I just started working at a curtain wall manufacturing company and I am lost. I would like to design the steel reinforcing we use in these mullions. Mostly are channels but they are not the type in the steel manual. The are either 10GA or 3/16" thick plates that are...
Thank you to both.
As you can see my problem is that the building is governed by seismic forces and the curtain window wall are goverened by wind loads. How are they compared? Is the manufacturer responsible to provide a connection that the curtain wall can deflect 3 inches? I understand the...
Hello Fellow Structural Engineers,
I have been recently hired and I am surprised by the design of window curtain walls and story fronts.
The allowable story-drift given in ASCE is .025, .015, or 0.020h. for a 10 feet story the allowable drift is between 1.8 and 3 inches.
The maximum allowable...
