    Floor Wood Truss Capacity

    Yes. We tried to find the supplier but no luck. I thought it might be something something similar to SJI tables. I guess not. Does the TPI have tables for the plates?

    Msquared48 - You are correct about the CG. Low seismic. No historical data at all. Building three story wall is too expensive. How would you calculate the overall stability of this wall?
