I have been tasked with evaluating an existing floor framing system to allow mechanical penetrations at an existing school. The 2nd floor consists of a framing system that is completely foreign to me. The system utilizes a 9/16" form deck and concrete, supported by open web steel joists, which...
In the last several years, the quality of information contained in wood truss submittals has deteriorated to a frustratingly terrible level of quality. We routinely see that the incorrect wind and snow loads are applied. We see the incorrect building code, incorrect enclosure classifications and...

As a structural engineer who has worked on similar structures, I have always assumed that this level of fire was a thing of the past in these types of structures. It will be interesting to see what comes out of the investigation and if this will lead to changes in the industry. These...
These are images wood floor trusses, taken from the floor looking up. The building is used as an assisted living facility. I cannot see how the floor would have been overloaded given the use of the facility.
Any thoughts on what could be going on? The facility was constructed in 1996. The...
I have a project that involves the renovation of an existing building. The building is 4 stories and utilizes structural terracotta for bearing walls. These are a fired, hollow clay product. I am looking for some resources on capacity and repair methods. The load on these walls is quite...

Pretty obvious what the issue is.
I have a daughter that is a senior in high school. She has done very well academically and with standardized testing. She has applied to a wide range of universities, from small, prestigious schools to large state schools. She plans to major in engineering (of some sort) and has a desire to...

This seems to be happening far too often.
I am evaluating a rather large (500k square feet) pre-engineered metal building. I am struggling to understand the lateral stability of one of the side walls. Is it possible that Butler used their Butler Rib II panels as shear panels? If so, does anyone have a suggestion as to the capacity?
I am at a bit of an impasse. I have a design/build project in which the general contractor wants to use a pre-engineered metal building as the frame and walls of a single story office. The architect (my client) has shown the use of gypsum wall board over metal studs which are supported by the...
The current governor of Ohio is proposing a "sales" tax on professional services. Do any other states or countries apply a tax like this. To me it seems like double taxation. We pay taxes on the profits (hopefully we have some), and on our wages. It seems that this may be setting us up for...
While getting ready to attend Christmas Eve church service, I brought up the subject of seating choice with my wife. It was not so that we could see or hear better. We attend a church that is fairly old (by American standards). Usually the Christmas Eve service is the most heavily attended of...
I have a project were I am designing steel trusses that span 80'. The trusses are spaced at 16' o.c. so the total tributary area for the truss is 1280 square feet. The trusses support purlins which will be placed at 2'-0" o.c. The pulins have a tributary area of only 32 square feet meaning...
I have a bit of an odd request. Does anyone know if there are any published guidlines for the design and construction of log cabins? I have a project to investigate the cause of some wall rotation and settlement issues.
Chapter 23 of the IBC does not specifically address these types of...
I routinely design foundations based upon the provision in the 2006 IBC for perscriptive bearing capacity based upon soil profile. Typically this ends up being on the low end at 15oo psf.
I have always used this as gross bearing capacity simply because I cannot find anything in the code that...
