Not sure where to actually post this, so here it goes. I have a project that is 5-story with a combination of concrete podium and 4-stories of wood. The 4-story wood structure is Type V, and the concrete podium is Type I. The issue is the 5-story structure has a base footprint of...
I am a working structural engineer and originally licensed in Texas. I have passed the SE-1, so not considered a SE. I can’t be grandfathered into a SE in Arizona, nor licensed as an SE, so if I obtain a PE in Arizona does anyone know what I would be limited to sealing? In general, most of...
Does anyone have the truss tables for the SST trusses by Standard Structures, Inc? They have since been sold, and their website is closed and all tables are gone.
I have a lot of California renovation projects that use the SST wood trusses, so hoping someone was smarter than me and...
If you have an equal bay spacing, which direction is the most economical way to frame your joist (parallel or perpendicular to the roof slope)? Basically, either your joist slope of your joist girder (or beam).
I've heard cases for both, but curious of your thoughts.
I have a load bearing masonry wall with a parapet. When determining the out-of-plane pressure on the wall I utilize ASCE 7-05, Section 12.11.1 (Structural Walls and Their Anchorage: Design for Out-of-Plane Forces). The argument arrived that the out-of-plane forces should be design per 13.3.1...
I am trying to figure out the configuration of an existing joist. It does not seem to fit the configuration that would help me determine the proper designation as specified in the 75-year Steel Joist Manual. Does anyone have any other suggestions to determine the proper joist callout?
What I...
I have a tall mechanical screen that will be constructed on top of the roof. There is a small gap seperating the roof and the screen. I am designing it as a parapet, but the wind load is very large. I am looking if there is a provision that would allow to design as something besides a...
If you have a multi-story, primarily wood structure, with shear walls bearing on a steel moment frame. How do you typically transfer the shear wall forces to the moment frame? I have heard of different methods for this connection, but would like to get a broader idea of the construction...
I have a school with a fine arts building. It has an opening for the stage of 45’, and I need to design the lintel. The CMU above is a 44ft and I feel I can not do triangle loading due to the need of control joints. Also, it is supporting a fly-loft and roof, because I can not do the triangle...
I have a soil report that recommends a 'California' style slab, or a waffle slab. Now, I am very familiar with a waffle slab, but what is a 'California' style slab?
My current firm uses grid lines that do not go through the entire structure. The generally stop the grid lines at the structures extent. In general, other places I have worked took the grid lines through the structure to pass through all columns on the grid line.
While I understand the...
Also, posted question in Geotech area, but not sure which area it better applies, geo or structural.
According to 1802.2.6 & 7 of the IBC, it is required to have a Geotech Report for seismic categories C and above. Is there something that is acceptable for a Geotech report not be performed if...
According to 1802.2.6 & 7 of the IBC, it is required to have a Geotech Report for seismic categories C and above. Is there something that is acceptable for a Geotech report not be performed if a more stringent analysis is used? I was informed there was such an entry, but I am unable to find...
I have run through the numbers on designing a tilt-up wall with a large opening. I want to model the wall in RAM Advanse, but having problems setting up a shell to run the analysis, and designing it as a concrete portal frame does not seem to be giving me the right numbers. Has anyone tried to...
Has anyone purchased the Civil Library from MathCAD? I saw it was around $250, and wanted to see if anyone has tried it out. I know I have other programs that can do probably everything they have examples for, but still like seeing all the numbers and comparing them to my own sheets.
I want a calculation to tell me if something is 'OK' or 'NG'. How do I write it in MathCAD? I can do it in excell, but unfamiliar with MathCAD.
ex. A=1
B=2
=if(A<B,OK,NG)
Granted that did nto work, and tried putting quotes but still not working. Any help would be greatly appreciated.
I attended a seminar awhile back, and the most interesting thing was the subject of compact sections.
- Most W-sections are always compact
- Only one W-section has a chance to be non-compact for Fy=36ksi -- W6x15
- Only seven W-sections have a chance to be non-compact for Fy=50ksi --...
I am in the process of using Geopak to help obtain beam offsets for a bridge. My question, is there a way to store and print the length of these offsets in order to have a printout at several locations? Does this require the use of the chain command? If so, how do I begin to set this up? I...
