verticle seismic forces for buildings

Question 1

lateral distribution of seismic forces, Fx

Answer 1

Fx = Cvx V

Question 2

Cvx

Answer 2

Cvx = Wx h^k-x / ∑ Wi h^k-i

Question 3

blank

Answer 3

Cvx = verticle distribution factor, V = seismic base shear, K = 1 (T≤0.5 second), K = 2 (T≥2.5s),

Question 4

T ≤ 0.5 seconds

Answer 4

Cvx = Wx h-x / ∑ Wi h-i

Question 5

T ≥ 2.5 seconds

Answer 5

Cvx = Wx h^2-x / ∑ Wi h^2-i

Question 6

story shear, Vx

Answer 6

Vx = ∑ n, i=x (Fi)
