Carbon steel welding is governed by CSA W59; which provides Table 4.4 for the minimum fillet weld sizes for welding different material thicknesses. I can not find anything outlining the same requirements for stainless steel. I have (2) pieces of 304 stainless steel to be fillet welded together...

NBCC 3.6.2.1.(6) requires a service room to be "separated from the remainder of the building by a fire separation having a fire-resistance rating not less than 1h." If a service room is located in the corner of an open building, and has a small mezzanine above it not counting as a storey, does...

Just to add to the confusion one supplier stated that S114 does not apply to their panels, and noted as I referenced above from the code, while Kingspan notes online that they have panels that are noncombustible per S114 testing (K-Roc panels). Just to be clear, this is a separate requirement...

The question I have is how do you determine if a type of Insulated Metal Panel (IMP) is noncombustible? In this situation the code requires a building to be of noncombustible construction (for my example NBCC 3.2.2.89). The NBCC definition of noncombustible construction notes by the use of...

My question is with the lateral bracing requirements of a continuous beam under a uniformly distributed load. For the image below the specific example I have has wall girts/roof purlins spanning (3) columns. The members will have sheeting on the outside that I am treating as a lateral support...

Thanks for the responses! Splitting the load makes sense, that would be relatively easy too with the angle being 45°. I wasn't sure if there were simple formulas to solve for

An example on this would be an HSS 4x4x1/4 (CSA G40.20). Z = 77.45 x 10^3 mm^3 (@ 45°), but I am not sure as to the hand calculations to verify this

I am looking for help with finding the section properties of square HSS members that are rotated 45° (i.e. diamond). I am using S16-14 to solve the moment capacity of an HSS beam, but I need to solve the Section Modulus (Z) first [Moment Resistance = (0.9)(Z)(Fy) , as per CL 13.5.a)]. The...

Not necessarily a structural question but I am working on a design with catwalks located above a network of bins. I need to determine what is required to meet code (NFPA 101 - Life Safety Code). My questions are below but here is the background for them. The catwalks are supported off of the...

I didn't realize something as simple as the image provided would count as bracing for the bottom flange as well. That's very easy from a fabrication side too. Thanks everyone!

Thanks for all the responses. If the purlins were to overlap as everyone recommends then technically it would not be a pin-pin connection (creates a moment connection). That would place the bottom flange in compression as EngDM mentioned. For an option depending on ease of construction, can a...

This is more of a general question but if a building has frames that are x ft apart, meaning the purlin span is x ft, when is bracing required on the bottom flange of the purlins? For this example I am meaning that sheeting is through fastened to the roof every 2ft, which is counting the top...

Thanks for the response kewli. Incorporating the full stress range leads into the last part that I had wrote then. Not sure how this Claus incorporates the endurance limit of steel. If the beam can only have the force applied in one direction at a time (resulting in stresses of 95 MPa or 85...

For Clause 26 of the Handbook it is covering the design requirements for Fatigue. I am not sure for my situation if this clause should include the stress range or if it is just the max stress value. 26.3.1 states stress ranges that are completely in compression are not considered, my case has...

Thanks for both answers! JoshPlumSE - We are also planning to use isolators which I believe will help reduce the chance of having matching frequencies. JStephen - This situation we have would be similar to what you mentioned. The dynamic load is provided as a point load which would be their...

The only information that is provided along with the dynamic load being applied is that the bowl inside the machine rotates at 4200rpm. There is no deflection limits requirement.

I have an independent platform made of steel that is going to be used to support two machines. The machines will not move on the platform but the internal components and motor can cause a dynamic load, which was provided by the machine suppliers. The dynamic load is point loads that are...
