This paper investigates a particular bridge construction technique
which could result in a significant torsional moment. The
structural member under consideration is a prestressed concrete
girder for which no torsional consideration is made.
Torsional shear stresses can be adequately approximated for
an I-shaped girder. Laboratory model tests were performed to...
Platelets undergo morphological changes essential to hemostasis upon activation at sites of vascular injury. The Rho GTPases Rac1, Cdc42, and RhoA drive these changes. Rho guanine nucleotide dissociation inhibitors (RhoGDIs) bind to the Rho GTPases to block the GDP from dissociating from the Rho GTPases, as well as anchoring the...
A method of analysis of arbitrarily shaped prestressed concrete
members for biaxial bending is given. The stress-strain curve of
the concrete is represented by two parabolic segments, and the
effects of strain hardening of the steel are included in the analysis.
An iterative numerical procedure is used to solve for...
The critical buckling load for round tapered columns with variable
end fixity is presented. The theory used is presented together
with the general solution for the resulting differential equation. This
general solution is solved by use of a computer. The computer program
written specifically for this thesis, the flow chart,...
This paper investigates the proposed preliminary designs of
two gymnasiums with respect to gamma radiation shielding due to
radioactive fallout. For each building a determination is made of
the protection offered from radiation fallout. If the degree of protection
is below the minimum value set by the Office of Civil...
