Hello~
what cities publish structural drawings with the permit set? I have read in this forum some engineers download them and have them as inspiration but I haven't been able to find one single structural set.
Thanks!
Hello!
We have taken some cores out of a structure and the individual cores go as 84.5%, 84%, 83%. None of them go below 75% but the average is less than 85%. Should I take more cores ?
Or should the structure be demolished?
Hello everyone I have a question about the design forces used for gas pipes supports.
The pipes undergo equal tensile forces Which they cancel out at the support F and -F. However, these forces get transmitted to the support, even when they also cancel out, the support sees the stresses. Is...
Hello,
I was wondering if I could use a slotted connection for the roof truss support that is designed as “roller” I get a maximum horizontal displacement of 3/4 in.
Could you recommend me a guide for this? I only have found very old details that recommend using this type of connection. This...
As you can see the following details, the base plate is connected to the concrete through rebars instead of J/L bolts. I am wondering if I can assume it is a L/J bolt in my calculation with the same diameter. The rebar strength is 60ksi. Welding is a more widespread practice in my city but I am...
I am confused about the property modifiers for the cracked sections under seismic analysis. Could someone shed some light in this matter:
1. I think only the elements part of the seismic resisting system are going to go under in inelastic deformation thus are the ones that crack.
2. Gravity...
Hello!
say you have a 6 in solid Section can you have it be welded to a 6 in tubular section With 0.25 in thickness. And Do you think if we have this 6 ft beam that is half solid rod and half tubular section, there is compatibility in deformations? I am having real trouble with this connection...
Hello!
I am confused as in what chapter I should use for seismic design of roof trusses in ASCE 7. I think it should chapter 13 or 15 because the roof is a thing of its own. What do you think?
Hello,
I have this truss that has the bottom chord in compression. The length between the truss supports is 90ft and the section is HSS. The joints in the truss are every 8 ft. The trusses are spaced 20ft.
When I check for compression in the bottom chord, the length is 90ft so my HSS fails...
Hello Everyone I have been losing my mind over the following:
How do I join two columns a HEB 300 and a HEB 240 through field weld no bolts.
It is a moderately seismic structure.
So I initially thought of using a plate that joined the two elements and then filling the gaps with vertical plates...
