I would like to know how different engineers design:
1. Stud splice (only for lateral/wind load)
2. Base connection design (thicker track or stiffclip if necessary) for cantilever (parapet) studs including the fasteners design (we specify STEEL NETWORK STIFFCLIPS under these circustances...
We specify self compacting soil (#57 normally) at the back of the retaining walls. Does it mean, we do not have to compact at all? BTW, I am structural engineer. Please help.
I am looking for a reference (design and detailing) for HSS to HSS moment frame connections. I called AISC, and was not that helpful. Do we have any manual or book, I could look into? I know this is not very common practice. I would appreciate your help.
I have a retaining wall located in front of the sheet piles as shown in the attached PDF, how much soil/lateral pressure do I consider in designing the retaining wall? To the point, how do I design the retaining walls? The sheet piles are already existing.
Per ASCE 7, what is the mean roof height (h) of a bldg as follows?
1. Office BLDG, flat roof (40'-0") with 2'-6" parapet.
2. Office BLDG, flat roof (40'-0") with 2'-6" parapet, and 12'-0" penthouse (penthouse covers only 25% of the roof plan).
3. Office BLDG, flat roof (40'-0") with 2'-6"...
I have an interior non load bearing 8" CMU wall between concrete floors (11'-0" floor to floor height). It is connected at base with dowels, however, not connected to the underside of the concrete slab at the top. I would like to connect at the top as well to make sure wall is laterally braced...
I have a condition where I am using 1/2" thru bolts to connect 2x_ lumbers, in shear connections. Is there any provision in NDS for minimum edge distance and minimum spacing between bolts? If yes, which section of NDS talks about it? I would appreciate your inputs.
If the CMU wall is interior wall, and I have wood ledger board attached to it, does the latter have to be treated? However, I understand if the wall is exposed to ground, it can absorb moisture, and the ledger board needs to be treated. Is there any reference that talks about this?
How do we design the concrete slab on grade? What is the procedure? I know the wire mesh is only for crack control, and is not designed as tension reinforcement.
I would appreciate your response.
If I drop a mass of 100 lbs from a height of 5 ft to a 10 ft simply supported beam (at the middle), how do I find out the actual moment/effect due to impact? I would appreciate help. I know it has something to do with impact loading, but I am not sure how to analyze.
I need to talk about wood 101 for Entry Level Engineers and CAD Designers in my office. This will go about an hour. I am wondering how do I start? What types of information about wood design I can talk about? I would appreciate your suggestions based on what you would do or you had done in this...
I have a situation in which my duty as a structural engineer is to tell my client if the code (IBC) has any design requirement for temporary structures like construction site protection fence design. Does IBC say anything about this? I looked at IBC, and could not find anything specific on how...
We specified 3500 psi non-air entrained concrete at slab on grade for a commercial project, and the GC poured 3500 psi air entrained concrete. Does it make a difference? I would appreciate your input.
What is the proper way of designing size of HSS load distribution member, as shown in attached sketch? Do we need to check the thickness of HSS for localized bending effect? If so, how? I would appreciate your help.
I am trying to find out the pull-out (tension) capacity of 1/2" dia. anchor bolt w/ 12" embedment into the concrete (I have 2x6 cont. P.T. sill plate over concrete basement wall). Where can I find this information? Does NDS manual has this information? I could not find it in NDS though. I would...
Could you guys talk a look at the attachment and comment on this? I have been told that total static moment, for a continuous beam with uniformly distributed load throughout the beam length, is always constant. Is there any book or article I can look at to proove this?
