Performance-Based Analysis of Steel Buildings: Special Concentric Braced FrameAdams, Scott Michael 01 September 2010 (has links)
The performance-based analysis methods and evaluation criteria in ASCE 41-06 were used to evaluate a special concentric braced frame building based on the design standards in ASCE 7-05. A rectangular, six-story office building was evaluated using linear static, linear dynamic, nonlinear static, and nonlinear dynamic procedures. The results showed that the linear procedures underestimated damage compared to the nonlinear procedures, with the building performing to Life Safety for the linear procedures, and the nonlinear procedures indicating component damage beyond the intended Life Safety limit for the 2/3 maximum considered earthquake (MCE) hazard. This trend continued to the maximum considered earthquake hazard as well, under which the overall building performance for the linear procedures did not reach the Collapse Prevention level, which occurred in the nonlinear procedures.

Crustal structure of the Tehuantepec Ridge and adjacent continental margins of southwestern Mexico and western GuatemalaWoodcock, Stephen Frederick 17 July 1975 (has links)
A free-air gravity anomaly map of the area between 10°-17°N and
90°-101°W shows distinctive positive and negative anomalies which
parallel the Tehuatepec Ridge. The positive anomaly approximately
overlies the topographic expression of the ridge. On the wide continental
shelf southeast of the Gulf of Tehuantepec a positive gravity
anomaly with an amplitude in excess of +100 mgal parallels the coast
for most of its length and turns abruptly inland at its northern end.
A crustal and subcrustal cross section constrained by gravity,
magnetic, seismic reflection and seismic refraction data and oriented
normal to the Guatemala continental margin indicates the positive
shelf anomaly is primarily the result of a relatively shallow
2.62 g/cm³ density block which may be continuous with and genetically
similar to the rocks of the Nicoya Complex on the Nicoya Peninsula,
Costa Rica. A crustal and subcrustal cross section normal to the
continental margin off southern Mexico northwest of the Tehuantepec
Ridge shows a shelf structure which is very different from the continental
margin off Guatemala. This suggests different tectonic
interactions at the convergent plate boundaries on opposite sides of
the ridge.
The Tehuantepec Ridge, in a crustal and subcrustal cross section
oriented normal to its trend, is shown to occur at the juncture of
two oceanic crusts of different structure and age. Southeast of the
ridge in the Guatemala Basin the crust is about 9.5 km thick and
northwest of the ridge the crust is about 12 km thick. Hence the
Tehuantepec Ridge is essentially a fracture zone, but because its
orientation is oblique to present plate motions and it is aseismic, it
is concluded to be a relic fracture zone. / Graduation date: 1976

Structures of the continental margin of Central America from northern Nicaragua to northern PanamaVictor, Linda 24 September 1975 (has links)
Gravity and seismic data obtained by the geophysical group at
Oregon State University on the R/V YAQUINA during 1969, 1971, and
1973 plus other available data over the area just west of Nicaragua
and Costa Rica indicate the tectonic complexity of the region. Gravity
measurements show negative free-air anomalies over the Middle
America Trench and the continental shelf of Nicaragua with values as
low as -120 mgal and -90 mgal respectively. An outer shell gravity
high of +35 mgal occurs between the lows. A large positive anomaly
attaining values as high as +110 mgal is associated with the Nicoya
Complex, a late Mesozoic assemblage, on the Nicoya Peninsula, Costa
Rica. Continuous seismic reflection records acquired along the continental
shelf of Nicaragua and Costa Rica indicate a large sediment-filled
basin off the coast of Nicaragua coincident with the large negative
gravity anomaly on the shelf. Free-air gravity anomalies and seismic
reflection profiles suggest an offshore continuation of the Nicoya
Complex. Two crustal and subcrustal cross sections of the continental
margin of Nicaragua show a large anticlinal structure near the surface
of the outer shelf. This structure and an underlying layer are postulated
to be marine sediments and basalts similar to those of the
Nicoya Complex. The cross sections suggest a ruptured oceanic
layer beneath the trench.
Imbricate thrusting of oceanic crust along the continental slope
is postulated as the mechanism of formation of the continental slope
and shelf, and hence the Nicoya Complex of Costa Rica. This model
has to be modified for southern Costa Rica where the Cocos Ridge
terminates the Middle America Trench. The present elevation of the
Nicoya Complex onshore may be attributed to imbricate thrusting and
concurrent uplift of the shelf by the Cocos Ridge during subduction. / Graduation date: 1976
