Diaphragm Analysis - My Journey
Most engineers will find a certain area of structural engineering that really excite them and areas that they absolutely despise, and for the longest time, I absolutely despised diaphragm design. Diaphragm design is complicated and confusing, my project managers loved to throw around the buzz phrases they had learned …
Lately I have found myself doing a lot of seismic retrofits of existing structures.
These buildings are often analyzed utilizing ASCE 41 and I have a few complaints with the standard that I have not found answers too... hopefully someone reading this site can help me out with these.

While this website will mostly focus on items in the architecture, engineering, and construction (AEC) field, I figured I could start with posting about how I made this website.
This website was created with the Django framework (a term I just learned throughout this process). It seems to be popular among …

How do you assess the fineness of the mesh required? More scale or load based?

@316Jq, The way I understand, the diaphragm design force (inertia force) per 12.10.1.1 is the inertia force.
Using the blog example numbers let's say this is 1392 kips.
The transfer diaphragm force could be estimated to be the delta in shears above and below the transfer level ~ (1500 - …

Just wonder how do you separate inertia force and the transfer force? The inertia force might be controlled by the Fpx,min per ASCE12.10-2, while the transfer force might need to be multiplied by rho or omega. This is also briefly discussed in NHERP design guidance you used.
