Hello. I am looking for a list of expansive soils. Can someone share a link. I have identified the soil as UtD per USDA, I would like to know more types to be aware of. This is for personal reference.
Thanks!
Greetings.
I am going over a nice brit document about portal frame plastic design but is in metric. I was wondering if anyone has come across a table with equivalencies for British UB shapes vs US W wide flange shapes. Any leads will be appreciated.
Happy thanksgiving.

Hello All:
Can somebody recommend and online calculator resource or free software to run some basic cooling loads for medium sized church in Dallas Texas.
Thanks a lot.
Hi. Am designing a Flitch beam with (3) 2x12's and two steel plates 8"x5'-0"x1/4" at the heAder bearing location for a garage opening that was increased from 16' to 17'. I determined the moment and distributed the stresses to wood and steel by their stifness ratios. Question I have is how...
Hello:
Am designing a 5000 sf home in NW Dallas metroplex. Soil turned out to be expansive from soil report. Geotech recommended raised concrete slab on piers. Am new to drilled piers but upon looking at some projects that I have seen in the past I was wondering why it has to be a raised...
Hello all:
For curiosity, what soil bearing capacity do you guys use as a benchmark for the need of piles in highly cohesive soil. Geotech is preparing soil report but I was wondering how does this play out when IBC allows for footing design assuming a 1500 psf without a soil report. This is...
Hello All:
Wondering what value do you guys use for something like this. Customer wants a very large area glazed facing his rear yard. He wants the header above doors the skinniest possible. I am running some quick frame FEA with SAP. What allowable out of plane deflection you use. There will be...
Hello all:
Working on a Strip Mall (150' x 35') project where cantilevered parapet is being extended eight feet. 20 psf wind controls. Roof structure is open web bar joists @ 5'. Upon performing structural analysis it is found a 0.9 klf at the roof/wall connection. Largest moment appears there...
Hello all:
Want to know your take on the topic of steel beams supported on wood columns or built up wood columns. I know it is generally not recommended, though allowed by some codes the support of masonry on wood. I know my wood column will be just fine, but want to know your practice and...
Hello guys.
My office designed a kitchen expansion where a new 12x4 type II hood was installed. It included a thru roof Exhaust fan and a Make up air unit. City came back with a few revisions. They want us to show air balance on schedule. I consulted with a mechanical engr and proposed to show...
Hello All:
Working on a project where I designed a framing system (metal deck + Steel Beams and Columns) to a new second story. While on design stage, owner had a safe installed which did not work with column placement. Now i am in a situation where two columns have to be shifted to a side 14"...
Hello:
I would like to know how you charge for value engineering work where not only big savings in material but also on labor and ease of construction are done to an original structural design. I.e.18 ga Steel deck with concrete to 22 ga without sacrificing obviously safety. Do you charge...
Hello all:
Working on a project where we are relocating an entire floor 18" above the existing level (one story bldg with basement. Basement to have a higher ceil) Previous system was wood frame on steel beams. Now we will have noncomposite concrete/Steel deck supported on new steel beams and...
Hello All:
I recall in a project before a plan examiner did not approve a proposed SFR (3000 sf two story) with 4" reinforced CMU. This was a local city limitation. On a similar project now and would like to know what your experience is using 4" cmu and if you had issues placing steel and...
Hello all:
I would like to know if any of you knows of a resource for the design of a small mat foundation 9'x9' for a heavy safe (70k). The proposed footing would be a mat foundation supporting (4) 8" concrete walls, 8' high. I have a book from my engineering courses, but it lists only mat...

Hello All:
Was wondering if anyone has any idea of where in IRC 2009 are provisions for Wall bracing of CMU walls?. My thinking is that wall bracing reqs regarding R602.1 were for wood or steel framing walls, but plan examiner is requiring this for a CMU construction. Any thoughts will be...
Hello:
Its been several years since I took a class on the above cited floor framing system. I recall the instructor skimmed us through a set of tables without going into the details of the design. Do you guys know of a web reference where I can analyze and design a floor system for a two bay...
