Md. 15TS 498:2021 Çizelge 6 — characteristic live loads by occupancy.

Md. 16Multi-storey reduction: α from Çizelge 7 based on N. Applies to columns, walls, foundations. Not for roofs or storage.

Çizelge 7N=1→α=1.0; N=2→0.9; N=3→0.8; N=4→0.7; N=5→0.6; N≥6→0.5 (minimum).

VERIFYOfis, A=40, N=5 → Q=400 kN; α=0.60 → Qred=240 kN. Confirmed.
