You may also add in your list : seismic ductile detailing aspects for industrial structures like long span pipe racks (box girders over columns) and long span trussed- portal frames with cranes (portal frame with stepped column). Thanks. Neeraj Agrawal ​ ------------------------------ ...

ASCE 7 does not cover this type of system. However, AISC 341 does specify a method to design knee braced systems. Please refer to Commentary of E1 in AISC 341-10 or AISC 341-16. You will find guidelines to design your system. In summary, you should consider R =3.5 or 2.5 (from Table 15.4-1, ASCE 7-10, ...
