Basically, this W10x12 outrigger had its bottom flange removed for aesthetic purposes without coordination of the structural team.
While the original beam was well designed for conservative eave snow loads, particularly heavy cornices have developed at the...
I have my first official client from hell. No need to go into details of it, but this simple $5k seismic retrofit project has been drug out by the client for months. She is EXTREMELY hard to work with, requesting multiple (unnecessary) changes, extremely late on payments, refusal to pay for...
I live in SF CA and I'm currently involved in a number of seismic retrofit jobs. These jobs are all wood framed residential units 3 to 4 stories over mostly open garage spaces. Basically your classic soft story type structure. Almost all of them are rectangular in shape aprox 25'X75'
Often these...
I have a built up beam and Im interested in calculating deflection under uniform loading conditions.
I have applied geometric principles to determine the compound moment of inertia, I, but I'm stumped on what modulus of elasticity, E, to use. I realize that the stiffer side members will absorb...
Hi all,
Im designing a shoring system for a contractor who is cutting floor joists for the work he is doing. There are shoring jacks supporting a second story load (with sleepers to distribute load) which rest just inboard of where he will be making his cut. As a result, I had intended to put...
This is a cross post. Not sure if thats frowned upon, but I know you structural folks will have good input:
Happy New Years Eave everyone. I have a question that I know is relatively basic, but I cant seem to wrap my head around.
At the most basic level of my design, I have a pile that will...
Happy New Years Eave everyone. I have a question that I know is relatively basic, but I cant seem to wrap my head around.
At the most basic level of my design, I have a pile that will be embedded into native soil some distance to be determined. It will also be exposed about ground a distance of...
I'm reading through ASCE7-05 trying to determine what section is most appropriate for determining lateral loading of a roof top deck that will be placed on a 4 story structure in high seismic zone (San Francisco). Was leaning toward using Chap 15 Nonbuilding Structures and using " inverted...
My client wants to put a glazed window in a non-bearing wall that is NOT rated for fire (OLD building). The window will allow light from the central stairwell of the building into the adjacent hallway. The city building dept. has said that she needs a 2 hour fire window if she wants to proceed...
I have some mechanical equip. on a 9th story and Im designing the anchorage of the equip to the slab. The manufacturer provided anchorage locations (see attached drawing) are pretty far in from the edges of the equipment, which results in very large uplift forces if one assumes that these are...
How are bolted connections through 3 sistered wood bending members calculated. Ive designed the beams based in relative stiffness, but I'm unsure how to determine demands on the bolts, say at 16" OC. Is it simply a double shear scenario using NDS and the shear at any given point along the beam...
Hello all,
I'm an early career engineer, (2.5 yrs) interested in making a move from a smaller hometown company to a larger structural company in the city. While I understand that ultimately I will have to learn and adapt to the in-house software that my future employer uses, I am interested in...
I'm designing a wingwall system for a box culvert out of mortared stone and geogrid. I have a nice set of construction notes for the geogrid but was hoping someone might have a link or input into the stone/mortar notes... for instance language referencing stone placement to avoid running joints...
This question is directed at anyone who attended/graduated from the California State University system with a degree in Civil. I'm interested in pursuing a masters degree with an emphasis on structural engineering. I've done the "normal" online research on the programs and course offerings of...
Curious what others out there would use for trip generation of a Visitor Center. site will have a 2500 sq ft visitors center with restrooms, gift shop, and exhibits.
The ITE descriptions for Rec Centers and parks dont really seem to match the intended use of this site.... any thoughts?
Im doing a cost comparison of CMU vs wood framed construction and could use your help. I have extensively consulted google but feel like I could use some advice from the collective voice. Im looking for final in place cost per sq.ft of building. Per linear ft would work too.
- first off, the...
