Hi All,
I have a bit of a conceptual question. What is the thought on combining local utilization of a member with global utilization of a member.
As an example, say we have an HSS tube that is in bending and is utilized to 55% of its capacity. And attached to that HSS we have a connection...
Hi All,
This has probably been covered before but I have not been able to find a succinct answer. I am in a situation where I sometimes need to reference ASCE 7 wind loading equations to determine loading on elements in Canada. I convert a wind pressure from the Canadian National building Code...
My question is related to ASCE 7 CH. 13 - Seismic Design of Non-Structural Components.
Suppose we have a component such as a stair that spans between two floors. In a seismic event we will have the basic component forces in the x & y direction due to the weight of the component being...
Hi All,
Question about splice welding a tension plate. We have multiple strap plates that are acting in tension only and due to the material procurement had to be spliced together to get the full length. Somewhere along the line it was relayed to the fabricator by the GC that these plates were...
Hi All,
Hopefully an easy question, when you have a bolted connection in a steel WF that gets abandoned for whatever reason, I have heard before and read (on AISC site here 2.5.3 - https://www.aisc.org/steel-solutions-center/engineering-faqs/2.5.-correction-of-fabrication-errors/#9503) that as...
Hi All,
I am looking for input, best practice/procedures, alternates, (any input really) on the pre-loading of steel beams used to reinforce an existing 2-way concrete slab. We have called for this to be done many times before but I am working on improving the process and making it more clear...
Hi all,
We are in the process of designing a glass curtianwall system that is supported off of vertical glass fins. Currently the face glass will be structurally siliconed to a hanger bar between the glass and the fin and dead loaded at each lite via setting blocks and steel tabs (shelf). My...
We have a project where we are looking to use bronze as the structural support elements. Does anyone know of any design information regarding bronze? We would also be happy with finding any projects or designers that have used structural bronze and talking to them to get some technical insight...
I am in the process of designing a point supported glass canopy in a high seismic area. The canopy support structure has been designed by others and the seismic design parameters used to design the steel support have been provided. My question is does anyone know of some good reference material...
Hi all,
I wants to get some input and feedback on how everyone works through their design process. Namely a few items and processes I am working through are developing record/project notes, calculations, models, etc. for a given project. Invariably the design/scheme of the project at the start...
I am working on analyzing windows in a low rise structure in Canada. My building meets all the requirements of the National Building Code of Canada wind loading code to use the combined CpCg values determined in figure I-8 of the commentary (Fig. 4.1.7.6-B of NBCC). My question arises in using...
I am using RISA for the first time to design an small industrial platform that will be used for man access to mechanical equipment (Note mechanical equipment is independent of the platform and does not impart a load on the platform). The reason I am doing this in RISA this time is the platform...
Hey Everyone,
I am attempting to design the connections of a new Jib crane to an existing stack wall for an industrial application, i have attached a sketch and detail of the brackets.
- The Jib crane will be a bought out item but the connection to existing will need to be designed.
- I will...
Hello All,
I am looking for a bit of confirmation on my process to make sure I am not missing anything (Please refer to attached detail). I am looking to reduce a continuous weld to a stitch weld to prevent warping during fabrication. Currently plate "PA" is welded with a continuous 1/2" fillet...
Hello All,
I wanted to start a discussion on the future of the engineering profession in light of continued improvements in AI and automation. There is a lot of talk about many jobs being "outsourced" to AI or that can be completed with much less expense than before. A few that come to mind are...
Hello All,
I am planning on writing the Buildings SE Exam in October of this year and lately have been overwhelmed by the amount of material. I have collected all the required codes and standards for the exam referenced by NCEES as well as the items listed at the end of this post. My main...
This may be a very straight forward question but I want to make sure I am designing for the correct loading one of recent projects. I have a piece of machinery that requires new supports. I have the raw weight of the machine and I am looking to obtain the factored load to design to. I see that...
