Suppose I have a rectangular building with five floors, each 10 feet high, 50 feet long in the x direction and 30 feet wide in the y direction. Suppose x is the direction perpendicular to the wind and y is the direction parallel to the wind. Suppose coordinate (0,0) is at the lower left side of the building facing the wind. If I know the wind pressures at each floor level, what would be the coordinates of the resultant wind pressures at each floor level relative to the (0,0) coordinate.

Three forces act at point O. Force F₁ has magnitude F₁ = 17.4 kips. The direction angles for F₁ are (α₁, β₁, γ₁) = (76.6°, 108°, 22.6°). Force F₂ = (−27.0i + 10.0j + 27.0k) kips. Force F₃ = (4.00i + 6.00j − 34.0k) kips.

Design a strap footing to support the two columns. These structural elements are spaced at a distance of 5.4 m center to center. Exterior column is 300 mm x 300 mm and carries a dead load of 250 KN and a live load of 300 KN. Interior column is also 350 mm x 350 mm in cross section and carries a dead load of 360 KN and a live load of 580 KN.

Use f'c = 21 MPa, fy = 276 MPa, and q-all net = 160 KPa. Assume weight of footing to be 9% of total load.

2. In each of the following cases, what kind of delay seems reasonable? Explain.
   1. The contractor is late but claims that it is due to inclement weather that has prevented him from placing concrete.
   2. The owner was responsible for providing structural steel for the project but could not deliver the steel on time to the project site.
   3. The contractor is behind schedule because he has moved his only large crane to another jobsite in order to avoid paying liquidated damages on that job.
