A client has a 12" wide, approximately 20'-0" high stone masonry gable end wall that is part of a detached garage. The garage is approximately 75 years old. The masonry wall is out-of-plumb 6" due to a large tree leaning on it. Is it possible to straighten out the wall (if so, how?) or is it...
Who is responsible for designing and providing the temporary lateral bracing for wood framing during construction? Is it the contractor's responsibility? Does the IBC (or any other code) address this?
Thanks.
Section 506.1 states "Seismic provisions of this chapter shall only apply to buildings built after January 1, 2003." In the state of NY, the applicable building code prior to January 1, 2003, was the State Uniform Fire Prevention and Building Code (the Uniform Code). The Uniform Code does not...
Ron/hokie,
I realized that I made posts with two different usernames...my old one and a new one. (Different computers had defaulted to different user names).

Sorry for the confusion.
Ron,
In response to your questions.
1. The stucco is direct applied. There is no lath.
2. The building was built in the late 1920s.
3. The building owner said it was constructed with "large terra cotta glass blocks."
4. They are icicles on the window sills. Not stalactites.
5. It is a...
I am designing a new building per the IBC 2009. I need to dowel into an existing concrete wall with an adhesive anchor. Can I still specify the Hilti HIT-HY 150 MAX adhesive? Or do I need to use the Hilti HIT-HY 150 MAX-SD?
Thanks for the responses. There is already steel on the job (the tunnel is a small portion of the entire project), so the steel trade is already involved. I was leaning towards the cast in place option as you both mentioned. Out of curiousity, are there any disadvantages to the steel/deck option?
How can you check a concentrated force on the 20" wall of an HSS 20x4x1/2? I would normally use AISC Chapter K for this design, but Section K1.3b limits the applicability to B/t less than 35. For an HSS 20x4x1/2, the B/t = 20/0.5 = 40. Does this mean that I can not provide a concentrated...
If I meet the requirements of ACI 14.5 - Empirical Design Method, then can I design any concrete bearing wall by this method? At what point do I need to consider slenderness effects per ACI Chapter 10 or ACI 14.8? I have a 12" concrete bearing wall that is 18'-4" high. The architects have...
I am looking for some clarification on a stability analysis and the Direct Analysis method. Is the DAM a type of stability analysis, or is the DAM just one step in the stability analysis?
Additionally, it seems that everyone I talk to has a different interpretation of the process for...
Everyone,
Thank you for the responses. I think these are all good solutions. If in fact I still go with the cast-in-place beam built within the plane of the wall (primarily because another engineer prefers that method), do you believe that is acceptable? We would run continuous vertical bars...
asixth, thanks for the response.
1. I wanted to give the contractor the flexibility to build the entire CMU wall shaft prior to erecting the steel. Therefore I do not want to provide a blockout in the wall. Another structural engineer on the job has recommended the cast-in-place beam option...
I have (2) questions regarding CMU...
1. What is the best way to attach WF beams to the FACE of a CMU stair shaft wall? I was considering a cast-in-place concrete beam with embed plates built in the plane of the CMU wall, and attaching the WF to the embed plates with a standard full depth...
