Hi,
I will be performing a calculation for a temporary support stand for a rebar cage for beams and column rebar assembly. The desired support is not fixed at the bottom. Construction has been using it for a long time with no issues but our client would want to stop the work and have an...
I am working on a project in Kermit and Wink, TX. I was looking for a drainage manual or any drainage design criteria but it seems the entire county does not have any concerns regarding floods in their areas and I cant find any city drainage manual. I've been looking in google maps and can't see...
Sirs,
I have this 24 inch wide beam that needs to be widened to support a wall on top. The proposed is 8" widening on the side of 24". Attached is the detail.
I designed the 24" beam to carry all the framing forces and loadings and as far as I know the widened portion of 8" will just be there...
Per ACI 318-14 22.5.1.2, Vu ≤ ф[Vc + 8*SQRT(f'c)bwd]
My understanding is that the 8*SQRT(f'c)bwd is equivalent to maximum shear reinforcement that you are allowed to put in your concrete beam section. But I cannot find any wording in the code that this is the limitation in the shear...
Id like to seek your opinion on this case. I am struggling to convince myself with this assumption from a senior engr.
The concrete joists (that connects to the girder) in ETABS were released in M22, M33, and T. The actual connection detail of the joist to beam is a standard hook which is fully...
Hi,
I would like seek your opinion on when is it required to apply special confinement in beams for ordinary moment frames where you have to include inner links to support every other bar like what you have in columns.
My understanding is ACI detailing manual recommends special detailing...
Hi,
I am designing a circular concrete pile with a steel column sitting on top of it. 1.5" grout was underneath the base plate. circular concrete pile is 36" in diameter. Factored shear is 24 kips. Vertical load is 53 kips. If i will consider friction using coefficient of 0.5, then friction...
Hi,
I have this case where a new RHS Beam will connect to an existing beam. The load is light since it was just a led sign. About 22 lbs. Plus computed wind load of 100 lbs.
Clients' preference is to connect this new beam using a through-bolts since they don't want to weld anything on the...
Hi,
Our office has a prospect project in Lagos Nigeria. I'm looking at the normal parameters used in designing structures and foundations in this region to somehow give a brief intro to our proposed team and start creating our design criteria. I'm used to structures designed in the United...
Hi,
Does anyone have a reference online where to find the wind data during the Hurricane Harvey (Aug. 25 to 30, 2017)? I've been using Corelogic but some zip codes have no information available and you have to pay an expensive amount of $45.http://www.eng-tips.com/threadminder.cfm?pid=507
Any...
I have a concrete pedestal 3’x3’x 4’-6” high supporting a 14”dia x 40’ high stack. It has 12 nos. of anchor bolts in a bolt circle diameter of 18-3/4” and is closely spaced at approx. 4.8”. The failure that I would like to focus on is concrete breakout in tension.
ACI 318-11 Sec. D5.2.9...
Hi,
I have a beam square hollow section (SHS150x8) connected to a column circular hollow section (500Dia15).
Attached is an excerpt from CIDECT design guide 1 referring to another design guide by choo.
Unfortunately, I cannot find anything relevant for me to check this connection subjected...

Suppose you have a flat plate loaded with two pressure loads coming from trolley wheels. The plate is giving one way distribution as shown in the attached.
I could design by strips but 12 mm deck plate seems not sufficient.
do you have any references how to compute for the centre and side...
Hi,
Imagine a structure with 4m column spacing in transverse direction pinned to 7m transport beam that is sitting directly on 2.5m wide spmt (SPMT - Self propelled modular trailer) deck without any fastenings.
Knowing that the structure is pinned, the bottom of the transport beam as also...
Hi,
I have been checking concrete panels which resists both lateral earth and water pressure. It is a bridging panel of 1m width and 2m length.
Analyzing this as simple beam of 1m strip and 2m length of 800mm deep, it fails in shear. Ultimate shear is 850kN.
Now, I havent taken into account...
I have a model of a raft footing.
When I check the slab stresses and pick the moment, it shows that meshes are not connected specially at point loads where columns are located.
Do you have any idea why is that?
I thought safe v12 is considering the end constraints already

Fellows,
I have a base plate with a circular hollow section. A certain portion of the base plate inside the CHS member has a hole of 40mm.
I have decided to use STAAD pro v8i to see whether having a 40mm hole will not affect the strength of base plate and the bearing capacity of my conrete.
I...
Fellow Engineers,
I have a steel lift of 16m high which should be design under shock loadings..in the specification it should be designed to 5g.
In the code it says "the static equivalent load acting on an "item" is obtained by multiplying the mass of the item by the number of g's specified...
