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?

Dik - In principle this is the same concept I have provided. Two straps one on each face. phamENG - The nail slip in shearwalls is mainly due to plywood nailing. The nail slip formula is (v*h)/(1000*Ga). Ga is a product of plywood. Is there another way to calculate the nail slip? SJBombero -...

Wouldn't the argument of straps not installed tight or wood shrinking be the same for shearwalls strapping? We use metal straps all the time.

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...

Greeting - 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...

Greetings - Is two ways bending allowed in wood posts? Looking at a high fence post (12-feet) that is from one side supporting typical fence on the other side the fence is cantilevered off the post (neighbor wall that we are not allowed to attached the fence to it) 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 John

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...

Yes. We tried to find the supplier but no luck. I thought it might be something something similar to SJI tables. I guess not. Does the TPI have tables for the plates?

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! John

We are to follow the IBC 2012, which references ACI 355. I still cannot determine the requirement. 200% is what the word is but still don't see it in writing. Does anyone know the exact reference?

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...

Msquared48 - You are correct about the CG. Low seismic. No historical data at all. Building three story wall is too expensive. How would you calculate the overall stability of this wall?

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...

Very interesting. One more idea from a coworker, the center bar had dirt on it. The contractor proposed plan is to clear around the center bar going deep until the grout is well placed around the bar, then fill the void with some sika product. They are very confident that this is limited. At...

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...

The underpinning is to allow grade beams and auger cast piles to be constructed for an adjacent building. The calculation does address rotation similar to retaining wall calculation. There is no moment verification at the location of the cold joint. There is one at the bottom of the original...

The calculation includes soil pressure verification. I believe this is for construction only. Once the backfilling is complete the soil pressure is balanced. I was talking earlier today to a friend engineer and his point of view was, there is no difference between the original footing to the new...
