A seller's form clearly states no warranty is included. The buyer's form states that the seller warrants the goods for one year. (UCC) In this case no contract can be created the warranty term is a "different term" and the majority of states hold that a contract can be formed but that the contradictory terms cancel each other out the warrant term is an "additional term" that becomes part of the contract in most states. None of these is true

Problem 3 A 5-story university building with occupancy greater than 500 has Special reinforced concrete moment-resisting frame, 120' x 100' plan dimensions and a height of 16 ft per floor. The Seismic weight can be calculated considering 100 psf at each floor and 40 psf at the roof. The building is located in downtown Los Angeles on soil with seismic site class D, and the seismic design response acceleration coefficient is 1.56. a. Calculate the total wind force, assuming that the windward face is 100-foot wide. b. Calculate the base shear due to seismic loads c. Regarding the seismic story forces at the 2$^{nd}$ level and at the 4$^{th}$ level, without doing any calculations, circle the correct answer below: i. The 4$^{th}$ level seismic story force is larger because all stories have the same seismic weight and level 4 is higher than level 2. ii. The 2$^{nd}$ level seismic story force is larger because all stories have the same seismic weight and level 2 is closer to the ground than level 4. iii. The 4$^{th}$ level seismic story force is larger because the wind pressure is stronger at story levels further away from the ground level. Answers: a. 214.8 kip; b. 1288.3 kip
