In the frame structure with seismic grade 3, is it necessary to follow the seismic grade for non-frame beams? Because the non-frame beam l itself does not need to participate in earthquake resistance,

In the third-level earthquake resistance, the practice of L shall be subject to the practice requirements on page 86 of11-1atlas. This page does not consider the seismic grade, but uses Lab and Ll.

There are two main aspects of earthquake resistance. On the one hand, it is the practice, which has been done in the series11,and on the other hand, it is the problem of La and Lae.

Theoretically, the frame part, in short, KL and KJ parts should consider seismic anchorage, and they use Lae, while L beams and plates can be used without considering seismic grade, and they use Lab.
