Info

For continuous beams, the following arrangements of imposed loads should be considered:

(a) alternate spans loaded;

(b) any two adjacent spans loaded.

The rare, frequent and quasi-permanent load combinations should be considered where the values of ^ and \p2 are taken from NAD Table 1(1). For imposed loads in offices ^ = 0.6 and = 0.3.

Rare combination, Gk + P + Qk Frequent combination, Gk + P + 0.6Qk Quasi-permanent combination, G + P + 0.3Q
