Does the size of a flare bevel weld have to be 5/8 times the thickness of the bent plate? If a smaller weld is required per calcs can the weld size be smaller. I am concerned about the heat a bigger weld will generate as the plate I need to attach is only 3/8" thick and the weld size comes out...
Can anyone suggest an anchor that has an ICC approval for cracked concrete with maximum 3/4" embedment to resist seismic load. This is regarding anchorage for seismic bracing in a PT slab for 4psf of suspended ceiling. Using an X-ray to miss the tendons to hang a ceiling ( 8' o.c ea way)- is an...
Does anyone know what is the delfection limit for deadload( gravity only) for the horizontal members in aluminum curtainwalls or storefront.
I have been using L/175, but some manufacturers use min of L/360 or 1/8". Where does the 1/8" limit come form. Is it in the code?

Can anyone tell me the code provisions for required steel stud joist blocking under a load bearing steel stud wall. Does the code address this issue? Are there any recomendations? My basic concern is if it has to be solid blocking under the wall.
Hello,
If I have a continuous member (say 5 span) would I use the centre to centre of supports(individual spans) to calculate the effective area for windload calculations or would I use the entire length of the continuous member (5 spans)
It is definitely conservative to use individual span but...

I am looking for an efficient and quick way to calculate torsional constant,J for mullion sections which are unique are highly complex (http://www.vistawall.com./details/fastnav/fastnav_frames.htm u can download from this website. I am dealing with a variety of sections.
It is time consuming...
Hi All,
I am working on a project with aluminum mulions. How does one get the section properties of the mullions. What is the typical way?
Especially if you need the torsional constant.
Thank you,
Hi All,
I am designing a Canopy 60'x60' supported on 6 columns, 3 on each side. The columns are to be designed as cantilevered columns. My question is that will I have to use a K=2 to calculate effective length? Secondly in the beam column equation (canadian code) what value of U1 ( the factor...
Hi,
The connection of a silo leg to a foundation has been designed. There are 4 anchor bolts on a rectangular the base plate. The shear and tension capacity of 2 bolts is sufficient. If I replace the 4 bolts by 2 bolts would the configuration matter. What is the minimum number of bolts...
