On the other hand, when the rotational capacity is large (e.g., μ d ≥ 4.0), ϕ is determined primarily by the resistance and safety factors for the steel (i.e., ϕ s = 1.0 and γ s = 1.0, respectively) because the moment strength of the cross section is dominated by the steel section.
When the rotational capacity is small (e.g., μ d ≤ 3.0), ϕ is primarily determined by the resistance and safety factors for concrete (i.e., ϕ c = 0.65 and γ c = 1.5, respectively) because the moment strength of the cross section is dominated by the concrete flange, rather than by the steel section.
Because s0min is larger than λ*, the cross section is approximated by the geometrical cross section; (11).
The cross sections were round and rectangular.
The total cross section was not determined.
Calculate the hourly capacity of coal transportation Q: Q = { 36}00,VArho (18)where V is 1.77 m/s; A is the cross-section of loads as to rear conveyor, because the top of the cross-section is open, based on the coals rest angle of 30°, the calculated coal transportation area A = 0.63 m2; ρ is the loose coal density, 0.85 1.0 t/m3, select 0.9 t/m3.
This is because TW2 with T-shaped cross section was idealized with the two-dimensional macro-elements; therefore, the shear-lag behavior of the flange wall in the vertical direction could not be addressed (see Fig. 5a).
Otherwise, the collisional cross section is zero.
The shape of the tooth is cross section is oval.
The shape of the tooth in cross section is round.
