I'm currently designing a residential apartment building. It is set up with 2 "block" types. One is a 2 story version; the other is a 3 story. CLT Floor system, so I'll be analyzing it as a rigid diaphragm. The architect has multiple combinations of these "blocks" to form a couple variations of the building.
I'm hoping to be efficient with my design and calculations and be able to analyze the "blocks" separately as laterally and vertically independent systems that just happen to be adjacent to each other, but I'm wondering how others interpret the code re: seismic joints required in between the two buildings.
I have done a group of (3) townhomes and the related permit comment was to verify that the three units are independent of each other, so that's what I was hoping I could do here, but my PM raised a great point that I want to further investigate about the seismic joint requirement.
also, does anyone have any useful CLT lateral resources? the fabricator has "goal" design values but no testing done yet - they will get there but are on an accelerated design path. They are hoping for 2-way panels with minimum post locations. I've located a few, but none give a full picture of system values/capacities compared with span tables, for example.
