A 3-story office building is to be designed and constructed in downtown San Francisco (where the short period spectral acceleration, Ss, is 1.5g and spectral response acceleration at one second, S1, is 0.6g).  The building will reside on a dense soil with soft rock (Site Class C).  Long period is 12 sec.  The structural system consists of special concentrically braced frames (SCBF) – see the following figure.  The dead loads are 70 psf at the roof and 100 psf at the floor levels.  At each floor level, the partition load is 20 psf (note that no partition load exists at the roof).  Do not factor these loads and ignore live loads when calculating the floor weights.   Seismic design category is

Specialization in production is economically beneficial primarily because it

A reduction in the level of unemployment would have which effect with respect to the nation’s production possibilities curve?

The floor plan of a 15-ft high one-story building is shown below.  The lateral load resisting system consists of 8” thick reinforced concrete structural walls around the perimeter (for simplicity, openings in the walls are ignored in the calculations).  The gravity lateral load resisting system consists of 16” square reinforced concrete columns and 7” thick reinforced concrete slab.  Concrete compressive strength (f’c) is 4,000 psi and concrete unit weight is 150 lb/ft3.  The center-to-center dimensions are: x1 = 15 ft, x2 = 17’-8”, x3 = 17’-8”, y1 = 14’-2”, y2 = 13’-6”, y3 = 13’-6”, y4 = 14’-2”.     The lateral stiffness of wall 1 is nearly
