I am designing a 12.25ft lifting beam that is picked up by lifting lugs on the top flange of the beam. The lifting lugs are welded at the ends, being 12ft (144") apart, which I believe means the unbraced length would be 144"? The load is picked up by lifting lugs on the bottom of the beam spaced...
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...
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...
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...
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...
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...
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...
