Consider a 7-story buildings with a total plan area BxL. In which B=125ft and L=60ft . The average weight of each floor and roof are 95 Ib/ft and 75 lb/ft?, respectively. The 84 ft-tall building is located in a seismic region with SDs =1.6 g and SD1 =0.5g for a building supported on rock, where g is the gravitational acceleration. The structure of the building consists of steel moment frames (all joints are rigid) that have an R value of 8. The importance factor I=1.0 Determine the total design seismic force (kips) acting at the base of the building ( seismic base shear in kips). ***the answer was between 339.5 and 342.5*** but I don’t understand how .

Step 2 1st condition Bending moment at hinge D =0 Rc*2 = (3*2)*(2/2) Rc = 3 KN Rc = 3 KN (upward) could you explain where these numbers coming? Why that divided by two? and is formula like this: 3kN/m*2m*2m/2m? 2nd condition Bending moment at hinge F =0 RB*2= (3*4)*(3+4/2)-3*7 RB = 19.5 KN RB = 19.5 KN ( upward) Same this formula If you can explain this like drawing this on paper and write where all meters and number come, that would be help me. If you could also tell the direction, where you would calculation them
