Is it possible to design a cross hipped roof, without a post beneath the ridge and without using trusses? Collar ties work well at a portion of the roof, but I'm not sure how to make this connection at the valley where the two hips intersect.
Table 12.6-1 of ASCE7-05 states that the equivalent lateral force procedure is permitted for certain structural characteristics. Would the Equivalent lateral procedure be applicable to a 3 story concrete building? I am confused by "regular structures w/ T < 3.5s and all structures with light...
The cantilever column makes sense. So the lateral force that comes out of the floor diaphragm is applied to the columns, correct?
What kind of connectors provide rigid connections between timber beam and steel post? I thought this connection was typically thought of as a pinned connection.
Hi All,
I have a question about an addition to the second story of a house only, leaving the bottom story open to the back yard. I had initially thought of using a moment frame or strong walls in the corners of this rectangular addition to transfer seismic loads, but another engineer told me to...
It turns out the 8" wide footing is a stem wall, not the actual footing. The contractor has not excavated the existing footing to see what is really down there. The client doesn't want to pay for adding spread footings, or excavating to see what the actual foundation's dimensions are. The...
There is a 16" high stem wall that the framed wall rests on. The contractor is telling me that the footing is 8" wide and 16" deep (below the slab). The house was built in the late 1960s or early 1970s, so I am not surprised.
Yes the beam is continuous over the posts that will be removed.
My concern with eccentricity is over the length of the footing. The wall on top of the footing is a non-bearing wall. So with a point load at the end of the 36' long footing and another point load 13' from the end of the 36' long...
My client would like to remove posts beneath two beams to make some space in the garage. I plan on using two steel channels to stiffen the beam. I have two questions:
What is the appropriate way to connect the channels to the post?
For the new, larger point loads on the 8" wide perimeter...
