Is anyone aware of design guides or design resources to repair and replace wood framing damaged by termites? The particular job has damage to roof trusses which would be difficult to remove.
I have a shear friction question. I am involved in a project where the structural engineer specified hollow precast concrete piles. See the attached sketch. This is already built. The connection of the pile to the pile cap is through rebar and poured concrete in the top of the hollow pile...
I am involved in a dispute with a contractor about a base plate connection to a concrete pier. The base plate is anchored to a concrete pier similar to the attached detail taken from Design Guide 1. The contractor's engineer is adamant that this can be a pinned connection. He is suggesting...
I am looking for resources regarding structural damage to a home from a lightning strike. The home is wood constructed, two stories, and in the south. I am seeing very little char. I am uncertain if all the observable damage is from a lightning strike.
Thanks.

I need to repair a damaged 4 inch concrete floor slab. A thin layer of the top surface has broken off. See the attached photo. The damage may be due to heat or corrosion chemicals. How would you repair it...
I need to determine the thickness of an existing foundation. The original drawings are missing. Would a rebar locator be able to determine the thickness? What other ways could I determine the thickness of he foundation?
What do you think is better and more economical, field welding or field bolting new steel beams to existing steel beams/girders? I need to connect new W8 beams to existing W12, W14, or W16 girders.
Thanks!
How do you comply with the requirements of AISC360-16 Chapter N? Do you restate the requirements of this chapter on your drawings or do you just reference Chapter N?
How soon after concrete is poured should the burlap and soaker hoses be used for curing? The slab is quite large, 60'-0" x 90'-0" and the work is in Florida in summer.
Recently I specified drilled piers (caissons)for foundations. Because the piers are round, I also specified round ties around the vertical bars. See the attached drawing. The round ties varied quite a bit in diameter. This made it difficult for the contractor to get the vertical bars in...
I am designing a canopy structure. Since there are no side walls, I consider it an open structure and thus there is no uplift wind pressure on the roof. According to Table 26.11.1, the value of GCpi is zero for an open building. There is wind load on the framing members. Is this how you...
Can anyone help me understand the sizes of steel beams in the Chinese building code? What size are the following members?
H250x125x6x9
H300x150x6.5x9
H500x200x8x13
I assume the first two numbers are the member depth and flange width in millimeters. Are the second two numbers the web and...
My question relates to the so called 10% rule in the IBC for Existing Buildings. Is the intent to allow alterations to a structure that increase in the wind or seismic loads by 10% without having to reinforce the structure? In my particular case the existing structure was built in the 1960s...
Does anyone know of a design resource for a steel column embedded in a concrete drilled pier? See the attached sketch. I need to transfer the bending moment and shear from the column to the pier. As far as I know there were no shear studs to transfer...
I am considering purchasing a drilled pier design software from a company called SoilStructure Software. I am looking for feedback on this program. See the link:
