I have seen the Simpson article regarding the new 3G epoxy. There are several problems with this example: 1) it assumes 3,000 psi concrete, as soon as you go down to 2,500 psi concrete the ductility ratio doesn't work and overstrength factor would apply again. 2) It assumes and 18" deep concrete...

In reference to the closed thread (thread507-420144) I would like to continue the discussion. I too do many retrofit projects that require installing new holdowns on existing concrete foundations. Typical construction here in my area of California is raised floor with 8" wide concrete stemwalls...

HotRod10, I'm using the "Flat Roof" snow load and not the "ground snow" load for the deck design. My post states I'm using ASCE 7-10 Sec. 13.3 to generate my seismic load which is the "seismic coefficient." FYI, wet saturated snow has a max density of about 30pcf, and yes I have personally...

Hello all, looking for some input from my fellow engineers regarding wood deck anchorage in areas with high snow loads. My questions are arising as I have been asked by a client to look in detail to these requirements. Upon looking in detail, and applying the building code (as interpreted) by...

hokie66 thank you for your reply. I am aware of the values for bolted connection in the NDS however I am a bit concerned about the proposed connection configuration. Perhaps the attached sketch will help clarify the situation. I have two glulams spliced at the center of the connection shown...

I have a situation in a building we are designing in which the architect would like to hang a glulam beam (used for the ceiling framing) from a W beam above used for the roof framing. Are there any code limitations to utilizing a bolted connection to hang the glulam from the W beam. It was...

PostFrameSE The only thing you are missing here is the fact that the building shown is perfectly symmetrical. Most buildings that you encounter in design will not be perfectly symmetrical as shown in Figure 6-10, so unfortunately the new code requires that all 8 loading patterns must be...
