Questions (*) a. The floor layout, total floor weights are W1=1250+5a kN (lower floor), W2=900+5a kN (upper floor) in the figure, and the static calculation of the building with a two-storey framed system, according to the Muto method, first, fictive Vt=100 kN base for the shear force and calculate the M - V section forces of the frame. Draw M-V Diagrams. Calculate the period T1 in the x-x direction using the Rayleigh method. Calculate the elastic maximum displacement values at ground level using the ERZİNCAN 1992 N-S acceleration earthquake spectrum of the recording under total design earthquake forces. (amax=0.40g) Notes: (a.For the reduced effective stiffness values of columns and beams, the coefficients of 0.7 and 0.35 will be used, respectively. Ignore the peak force AFN.b. For the Muto method, use the triangular table of the yo coefficients of the horizontal load.) All Columns All Beams 10.0m 10.0m 0.70 m 0.30 m 0.70 m 0.30 m 5,0 m B Lower Story-h1=290+5b (cm) Top Story h2=245+5b (cm) R=8 Concrete: C35 >Ec=33x103 MPa - m2 h2 b. Using the storey stiffnesses and storey k2 weights of the system you calculated above under statically equivalent loads, calculate the real stiffness and mass values of (2x2) m1 h1 and create their matrices. 2-a. Using the [K] stiffness, [M] mass k matrices you created above, create the frequency equation. Calculate and plot the natural frequencies w1, W2 and {0}1,{0}2 mode shapes. b. Check the orthogonality of the modes. Calculate the participation factor, generalized masses, 1st and 2nd effective masses. Do you think statically equivalent calculation is sufficient for this structure?
c. Using the modes, masses and acceleration spectrum of 1992 ERZİNCAN earthquake N-S record for which you calculated the dynamic calculation of this system, calculate the base shear force and calculate the values for the floor forces R=8. (amax=0.40g) d. What would be the floor displacements (max. floor displacement) of this building in each mode and in its total? e) Check the dimensions of the columns and beams of the building according to the earthquake code TDY(2018) and TS500 standards, calculate the minimum bending and shear reinforcements and draw the sketches. f) Considering the reinforcements you have placed, show with your calculations whether the "columns are stronger than the beams" condition is provided and also that the "column-beam junction areas" are safe against shear force.
