One of the beams are already under fabrication and I need to make extra holes into that member. Is there a provision for post installment of bolts holes? I tried to look for one in AISC or RCSC but no luck. I am concerned about post drilled bolt holes not having zinc coat on them and cause...
I am designing a column with high shear and moment. I used a shear lug and it's calculating for concrete breakout in shear by shear lug. However, it's still failing. So I clicked on shear reinforcement for anchors but that didn't do anything. Is this because shear lug is meant to take all the...
Thank you for the response! That makes sense. U can just be 1. I thought U had to do with specific eccentricity.
Based on your shear lag description, U accounts for unintended loading on other connections. If gross area were to be used for tension or shear, it would assume all area is acting...
Hi, I wanted to ask the community about my confusion on steel connections. For your reference, I use AISC.
1. Is it possible to have multiple U factor for the same tension members? For instance, a diagonal member will experience tension in two directions. Do you calculate U factor when the load...
Hi,
I am a young engineer designing for gusset plates. AISC J4.4 deals with compression of connecting elements. However, if the slenderness is over 25, it says to apply chapter E. How do you apply chapter E for plates exactly? Table E1.1 shows limit states for each cross sections but I don't...
I am making an x brace that is connected by a plate in the middle. However, it's not 4 individual members joining together in the middle. Two members are just crossing each other connected by plate in the middle to reduce unbraced length.
If I were to make 2 elements crossing each other...
Hi, I am a young structural engineer. I am calculating for concrete break out strength of anchors in tension. The vertical black lines between the concrete are the anchor rebars. The situation is depicted in the picture above.
Do you know which concrete is more critical? Rebars are embedded 4...
