It has been undertaken here to use the matrix method of
structural analysis for the determination of the stability of elastically
restrained, simple portal frames. This involves the formulation of
the stiffness matrix of the structure in terms of the axial force in the
members. The stability criterion, when applied...
Helical anchors are a type of deep foundation element that can be installed quickly in almost any location and can accept the immediate application of operational loads. The use of helical anchors has expanded in recent decades from its established application in the power transmission industry to more traditional civil...
This thesis presents a matrix analysis of structures
with semirigid connections. The stiffness factor of a
connection has been assumed to be a constant as represented
by the initial relationship of moment versus
rotation. Three cases are considered: Case I - structures
with semirigid connections, column width and beam
depth...
Our studies and those of our colleagues in Idaho indicate that the western Snake River Basin is a major geothermal province, similar in some ways to the Imperial Valley Geothermal Province. Deep drilling should encounter high temperature fluids in permeable rocks below 2 km and at shallower depths where permeability...
Wright's Point, a 250-foot-high, sinuous, flat-topped ridge, projects eastward into Harney Basin, Harney County, Oregon. This 6-mile-long feature ranges from 200 to 600 yards wide and merges with a broad mesa at its western end. The nearest topographic highs are Dog Mountain, 2 miles southwest, and foothills of the Blue...
