A Policy Guide to Steel Moment Frame Construction


Quiz Questions

1.All steel-framed buildings derive basic structural support for the building weight from a skeleton (or frame) composed of horizontal steel beams and vertical steel columns.
True
False
2. In steel moment-frame buildings, the ends of the beams are rigidly joined to the columns so that the buildings can resist lateral wind and earthquake forces without the assistance of additional braces or walls.
True
False
3.What does WSMF mean?
Welded steel moment frame
Welded stud manufacture frame
Wide steel moment frame
None of the above
4.WSMF construction has also frequently been used for mid-rise and to a lesser extent, low-rise commercial and institutional construction, auditoriums and other assembly occupancies, and has seen limited application in industrial facilities.
True
False
5.Rapid inspections conducted by building departments after an earthquake are intended to identify those buildings at greatest risk of endangering the public safety. They are enough to detect all damages a building has sustained.
True
False
6.Is it technically feasible to upgrade an existing steel moment-frame building and improve its probable performance in future earthquakes?
Yes
No
7.When steel braces or masonry or concrete walls are added to a building, they stiffen it and reduce the amount that the building will sway in an earthquake.
True
False
8.Energy dissipation systems reduce the amount that buildings sway in an earthquake by converting the earthquake’s energy into heat.
True
False
9.Basic factors that affect selection of an optimal alternative include the individual building’s characteristics, the severity of motion anticipated at the building site, desired building performance, cost of the upgrade, the feasibility of performing upgrade work while the building remains occupied, and the effect of the upgrade on building appearance and space utilization.
True
False
10.The Simplified Loss Estimation Methodology contained in FEMA 351 consists of a series of graphs that indicate the probability that WSMF buildings will experience various levels of damage if they are subjected to certain levels of ground motion.
True
False
11.The amount of damage that a building will sustain in an earthquake depends on a number of factors including the configuration and strength of the building, the quality of its construction, and the specific characteristics of the ground motion produced by the earthquake.
True
False
12.Studies conducted under the FEMA/SAC program to reduce earthquake hazards in welded moment-resisting steel frames confirm that some of the design requirements contained in the building codes prior to the Northridge earthquake were inadequate.
True
False
13.FEMA 350 contains design criteria for twelve different types of prequalified, welded and bolted beam-to-column connections. Each prequalification includes specification of the limiting conditions under which the connection design is valid, the materials that may be used, and the specific design and fabrication requirements.
True
False
14.The cost of a steel frame building is generally dependent on the amount of labor required to fabricate and erect the steel and the total number of tons of steel in the building frame.
True
False
15.The objective of most building codes is to design buildings such that they might be damaged by severe earthquakes but not collapse and endanger occupants in any earthquake they are likely to experience.
True
False
16.Construction quality control includes that set of actions taken by the contractor to ensure that construction conforms to the specified material and workmanship standards, the requirements of the design drawings and the applicable building code.
True
False
17.Construction quality assurance is that set of actions, including inspections, observations and tests, that are performed on the owner’s behalf to ensure that the contractor is conforming to the design and building code requirements.
True
False
18.Many of the new design recommendations are compatible with existing building code regulations that are already in force around the United States.
True
False
19.If inadequately constructed, welded joints in moment-frames can be weak links that fail prematurely.
True
False
20.In addition to safety concerns, many owners and tenants in buildings are concerned with their ability to return to a building after an earthquake, and continue to live or work in it. FEMA 351 provides an evaluation procedure that may be used to determine the probability that a building will experience so much damage that it should not be reoccupied following an earthquake.
True
False
