Does ASCE 7 addresses this at all? Stumbled over the thread507-483715, which suggests using chapter 29.
I don't believe the ASCE address this case at all.
Any suggestions?
Hi everyone, thanks for reading.
I am working on a residential project with a flat roof and a wood deck on top of it. One side of the deck has a parapet that also serves as rail to the deck. Balloon framing is an option but with a high ceiling and a few feet of space between the deck and the...

I have been called to inspect cracking in drywall. This is in exterior wall-top level-row house-60 years old.
The cracking is random. The structure does not show any type of movement or stress.
I attached a picture of the drywall.
Any ideas?
BTW, I hope I am posting at the right...

Thanks in advanced
Hello -
I am using Woodworks sizer and concept. It seems that the software is requiring every design for all wood members to be verified for fire design.
Is this a requirement in the IBC? or is it just something WoodWorks folks decided to added?
Thanks

Hi All -
I have inspected an attic with wood trusses. It was built 40-years ago. I found numerous number of split members. The members are in both tension members and compression members. I could not identify a pattern. They are random. This image represents the type of cracks I found.
I did a...
Hello all -
We are trying to evaluate existing floor wood trusses. The contractor wants to hang some mechanical equipment.
Is there a place where I could find the capacity of these trusses? We have double cords, 20" deep and span 27feet in commercial. Or do I have to run the numbers?
Thanks...
Hi all -
I am reviewing engineering drawings. The firm has provided calculations stamped by one of their engineers and drawings stamped by another engineer. Not that it matters, but both engineers work for the same firm.
Is there an issue with this?
Thanks in Advanced!

During the installation of a storage facility, we failed to inspect the anchor bolts during installation. Now, the code department is asking us to perform a pull out test to verify the installation.
The designer load calculation shows 6000lbs in tension on that anchor. Should the anchors be...
Trying to add a new level on top of an existing two wythe (8-in ). The original house is an end unit two story row house (about 80-year old). The wall is tied to the joists with a star and bolt system. There is a tilt in the wall that start from 0 at the roof level, 2-inch at the second floor...
One situation in two different projects:
1- Area under S.O.G.. Unsuitable soil was found and removed. The testing agency proposed filling with geotextile fabric with 57 stone. The Geotechincal Engineer rejected it.
2- Area under road. Unsuitable soil was found and removed. The testing agency...
We have done 24" Auger Cast Grout piles. The piles have a center bar and a cage bar. The piles were over poured by 3 feet (as designed). During chipping the extra 3-feet we found a void around the center bar at the bottom of the extra grout.
The contractor said this is typical. They claimed...
Underpinning a wall footing of a two story masonry building (not much loads but very very critical structure)
The underpinning (no reinforcement) is segmented at 4-feet each. The depth is about 5 feet down from the bottom of the footing.
For one of the segment, the contractor ran out of concrete...
Three separate foundation systems. All are in the same job site and all are delegate design. There are Underpinning, Auger Cast Piles, and concrete driven piles.
We initially had the driven piles go in first, then underpinning, then auger piles.
We had delays and at this point we are going to...
What are the bases that the IBC/ASCE uses to determine the live load on structures?
For example, the live load for an Assembly area with movable seats is 100 psf. The IBC requires the Occupant Load to not exceed one occupant per 5 square feet. Assuming the average person weight to be 250 lbs...
I was called to evaluate a 1930 roof structure and the possibility of installing a roof top 1000 lbs A.C. unit.
I was not able to locate any grading or stamps on the 2x10 wood joists.
Any suggestion on how to find the design values for these joists?
The Geotechnical report requires the removal of the man fill layer to access a suitable soil. This layer is 8 feet deep.
The site is about 185x130 feet.
The shallow foundation design requires about 50 single footers.
We were asked to provide a cost comparison between deep foundation and shallow...
