Hello All!
I recently utilized ASCE's Salary Calculator and I discovered that my earning potential does not meet my current salary. I am in the process of writing a letter to request a raise to a salary that is commensurate to my experience and talents. I would like any advice on how best to...
Hello All!
I am preparing to take the PE Civil Structural exam for the first time in October 2021. Please reply with what each of you used to study and pass the exam. I have found a lot of engineers who recommend the CERM book and NCEES Civil Structural Practice Exam book. I have also seen...
Hello All!
I am currently using virtual joists in my RISA3D model, because I am using 18k5 joists in my design.
Unfortunately, I've read info from SJI and talked to RISA support and I cannot figure out how to determine the equivalent/corresponding virtual joist for the steel joist that I am...
Hello All!
I am a relatively new engineer and I'm really stuck on a project trying to design an unbraced, slender reinforced concrete column. I have read through my RC concrete design textbooks and I am extremely confused. My conclusion from reading is that it is very difficult to do these...
Hello Everyone,
I'm designing my first aluminum beam and one of my beam ends is double coped. I know that I need to check block shear rupture for the coped end, but I also know that the capacity of my beam should decrease due to the copes.
Can anyone point me in the direction of literature...
Hello Everyone!
I am designing an "All-Bolted Single-Angle Shear Connection" for the first time and I have no clue if I need to check for block shear rupture.
Background:
I am designing a connection for an aluminum simply supported channel beam using a single aluminum angle with stainless...
Hello Everyone!
I'm very aware that this may seem like a very stupid question, but I'm stumped so please be kind LOL.
I am designing an aluminum beam for the first time and I need to check the interaction between local buckling and lateral-torsional buckling.
When Fe (flange's elastic...
Hello All!
When using finite element analysis (RISA 3D) to analyze underground concrete tanks, I often get abnormally high shear results at the corners of the tanks. The plate forces at the corner plates will typically be substantially larger than the adjacent plates. Very early in my career, I...
Hello All!
Any help would be very appreciated. I need to analyze a 100+ year old underground structure with groin vaults and weird curved side walls. I originally tried modeling the structure in Revit and exporting it to RISA 3D, but only the columns show in the RISA model. So now I'm in the...
Hello All [bigsmile]
Please see the attached photo of the concrete steps separated from the building. The client wants to seal the opening to prevent further separation and to also prevent water and debris from getting into the space. I believe they should be able to use backer rod and then a...
Hello All!
I'm working on a wall replacement (someone drove into the side of a building and the wall needs to be replaced). The existing roof is hollow core plank and I need to determine the roof to wall connection. Is it possible to dowel into the existing hollow core? Does anyone have another...
Hello All!
I'm working on a historic theatre renovation and the architect just let us know that they plan to add acoustical plaster to the existing plaster dome. I'm trying to determine if the additional weight is more than the allowable 5%, but I cannot determine the weight of the existing...
Hello!
I'm designing a manhole with about 3' of soil above it. The manhole is below a street. I do not believe that I need to check punching shear on the top slab because the traffic loads should be distributed before it reaches the top slab, but I was told to check the code to be sure. I...
Hello All,
I'm a new engineer who works on tanks often. I was taught to use software for the design of the walls. I typically use the PCA Rectangular Concrete Tanks 5th edition book for my base slabs. I would prefer to do all of my calculations by hand, but I'm not exactly sure how. I think I...
Hello All :)
I'm working on the design of a few underground tanks and I need to know how to specify what kind of waterproofing should be used. Could someone provide the requirements for waterproofing an ACI 350 underground tank? After some googling, I found that ACI 515.1R-79(85) probably has...
