I've been working through the design of a two-way slab based on the elastic frame method in the CSA A23.3 standard, and there is one part of the code that is unclear to me and I don't have the commentary or reference in terms of the rationale behind these provisions.
Based on my understanding...
This might come off as a bit of a rant, but I'm wondering if there is a good guide on how to properly setup the automatically generated load combinations for steel design based on the National Building Code of Canada?
The first frustration I found was in setting up the notional load. You can...
I'm evaluating repairs being done to some residential roof trusses. At the dormer locations, the top chord (2x12) of the truss is notched to allow it to sit on the 2ply - 2x8 header. I'm estimating the depth of the notch to be 5.3in which would exceed the maximum 0.25d allowed in CSA 086. My...
I searched through the threads and the only thing I could find close to my question was in the following topic: https://www.eng-tips.com/viewthread.cfm?qid=425321
Under the design options, I see there is an option to define the live load reduction factor for a member. I assumed that it would...
I'm reviewing the structure of an existing home. There is a continuous W200x27 beam that's supported on posts at every 10-14' by jack posts. Wood joists bear on the top flange of the beam, and the overall length of the beam is ~64-65 ft. The building was designed under Part 9 of the Ontario...
Hey everyone,
I'm looking for guidance on checking/specifying an intermittent fillet weld design based on the Eurocode from people far more familiar with it than I am.
Looking at EN 1993-1-8, clause 4.3.2.2, I noticed the first provision states "1. Intermittent fillet welds should not be used...
Hey everyone,
I have a question concerning the bearing strength in FRP. The ASTM D953 standard defines the bearing strength taken as the force at 4% hole deformation divided by the bearing area (hole diameter x thickness).
What is the reason for choosing 4% hole deformation as the strength...
Hey all,
I'm currently performing a review on design calculations submitted to us and one of the HSS beams in the structure has two point loads with an eccentricity to the beam's centroid. The connection of the beams to the columns is achieved using a plate slotted through the HSS and bolted to...
Hi everyone,
I've run into a scenario that has me puzzled with one of the projects I'm working on. I'm more interested in the theoretical aspect of the problem.
It's a retrofit, where I'm adding some beams and columns to provide additional support to a roof. The roof itself is made of...
Typically we use welded shear tabs on CHS columns which we use to connect beams, braces etc.
For various reasons which I won't get into, some of my colleagues are looking to move away from this detail, and instead use something similar to a friction collars (custom part) and have the shear tab...
I'm looking at the maximum bolt spacing design provisions from AISC and doing a comparison to the Eurocode which I'm more familiar with. Section J3.5 states that the "longitudinal spacing of fasteners between elements (...) shall be as follows:
(a) For painted members or unpainted members not...
I don't usually ask a lot of question but here goes.
For some background info, my boss has developed a new joint connection detail for deck panels that will be subjected to cyclic loading. Several other senior individuals in my company have voiced their skepticism that it will work as intended...
Starting with a little background on myself.
I'm on my first job after graduation, and I've been working there for a little over 2 years. I work for a relatively small company that develops products with applications in typical civil engineering structures. As part of that, we sometimes...
Hi,
This is my first post on these forums, but I have been lurking for awhile and find them very informative. On to my question.
I've been asked to perform a preliminary FEA of a simple structure which consists of a frame with primary beams connecting to the columns, and secondary beams...
