Question

1) In addition to recording the size, section and relative locations of structural members(design output), IBC 1603.1 also states that structural engineers must indicate______(design input) on the- (4 pts) 2) A flexible building will have ato a rigid building. The flexible building will experiencecompared to the more rigid building. (3 pts)frequency and aperiod comparedseismic forces 3) The IBC lists site classifications for types of soil, from hard rock to soft soil prone toliquefaction (A - F). Typically, theengineer will perform tests onthe soil to determine the site classification. Structures built onsoilwill experience higher seismic accelerations due to wave(3 pts) 4) Carbon dioxide emitted during the manufacturing, transportation, and construction of building materials (including structural elements) is known a______carbon. (2 pts) 5) You are designing a truss for a sports arena. The owner would like to hang a 20 kipscoreboard in the center of one of these trusses. They have proposed attaching thecables at the locations shown below. What change, if any, would you propose to improvethe efficiency of the truss? Justify your answer. (4 pts)

6) The metal clips in the wall at the top of the photo (A) will support the brick veneer againstloads. The shelf at the floor level (B) will support theof the brick. (4 pts)

7) You are testing the tensile capacity of two rods made of different metals. The first rod that you test elongates rapidly and ruptures after applying 2,000 pounds of load. The second rod hardly elongates at all and ruptures after applying 4,000 pounds. On thestress-strain curve below, the first rod is_______The second rod is____---The rod with the higher ductility is- (3 pts)
