Hello, cracking in the interior wythe of sandwich-type concrete tilt panel is occurring on one of my projects. The wythe is reinforced with mild steel, welded wire fabric, and a proprietary truss wire system to create composite action between exterior and interior wythes. The interior wythe is...

I agree, I'll add another bolt. Thanks!

Hello, I am designing a connection between a 5.5"x16" glulam beam and the top of a concrete wall. I have attached a potential connection detail where a steel bucket is attached to the wall face with screw anchors. The beam is skewed 35 degrees, supports a snow load of 14 kips and lateral wind...

Yep, I was going to reapond earlier. Going with a ribbon. Thanks forthe responses.

Hello, I am designing a residence where all openings (doors and windows) are floor to ceiling. Single story house. This will cause a break in my diaphragm chord at every opening. I am planning to pocket the headers into the trusses. However, to create a continuous chord I am a little leery...

dhengr: I believe I understand now. The ripped section on the far end will screw to the bottom of the plate, concealing the connection. I like this detail. Hot rolled Z sections are difficult to find, instead I have detailed two angles with 2 stiffener plate connecting them. The stiffener...

With the connection being at mid span of the stacked beam, I would rather not allow notching for a mortise joint. I am detailing a mortise and tenon for the condition where a post is located. I expressed my hesitation with a knife plate to the architect, and they said an "almost" concealed...

Hello, I am designing a custom knife plate for some heavy timber beams. Typically, I would go with a proprietary hanger, but this case is unique. The Main Beam is (2) stacked 12x14 DFL beams, the side beam is a 10x10 DFL. The Side beam is centered in the stacked beam. The connection to the 10x10...
