Their primary objective, in relation to seismic resistance, is to transfer axial forces as collectors or distributors as a part of diaphragm. WebNov 2, 2016 · In seismic design some members may be required to be designed to an overstrength load. In addition, the lateral system subjected to seismic forces may be required to have some redundancy. In RISA-3D, this is done by creating load combinations with the Omega (overstrength) and Rho (redundancy) factors applied to the earthquake …
