Using Two Different lateral system in each direction with different R and Cd
Using Two Different lateral system in each direction with different R and Cd
(OP)
Hello,
Does it makes sense to choose a lateral resisting system category in each direction? With different R and Cd? If I have non-load bearing precast shear walls in the Y-axis and load bearing precast shear walls in the X-axis, Knowing that non-load bearing precast shear walls have higher ductility and higher R, Is it permitted to take Non-bearing walls under Building frame System category with R =4 in one direction and taking R=3 in the other direction (Load bearing shear walls)?

Also review sections 12.2.3 and 12.2.4 for more insight into how the code requires us to designate MSFRS.
