Finite element modeling of reinforced concrete beams externally strengthened by FRP composites

Creator:: Potisuk, Tanarat
Abstract:: Three-dimensional finite element models are developed to simulate the behavior of four fill-scale reinforced concrete beams. The beams are constructed with different fiber-reinforced polymer (FRP) strengthening schemes, and are modeled using ANSYS, a commercially available finite element analysis program. The experimental beams replicate the transverse beams of the Horsetail Creek...

Design, analysis and evaluation of bridge superstructures for live loads

Creator:: Turan, O. Tugrul
Abstract:: Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...

Finite element modeling of reinforced concrete bridge columns with steel jackets using plastic hinge integration

Creator:: Carlton, Adam K.
Abstract:: In recent years confinement requirements for concrete columns have increased in seismic regions. Steel jackets are one way to confine reinforced concrete columns. The increased confinement provides additional strength and ductility for the columns during seismic events. For reinforced concrete columns with steel jackets, there are different section properties in...

Development of an ACIP pile-specific load-displacement model

Creator:: Adami, Nasim
Abstract:: Augered cast-in-place piles, also known as ACIP piles, have been used for more than seven decades in the United States and have gained in popularity due to their relatively quick installation and cost-effectiveness. Owing to the reduced impact on the neighboring environment as compared to some other deep foundation installation...

Electrochemical modeling of cathodic protection systems applied to reinforced concrete structures

Creator:: Muehlenkamp, Erik B.
Abstract:: A numerical model for the cathodic protection of steel in reinforced concrete is developed. Parameters are set to represent a three-dimensional section of a bridge beam exposed to the atmosphere and coated with a thermally sprayed zinc anode. Both diffusion of oxygen and conduction of charge within the concrete are...

New acoustic emission applications in civil engineering

Creator:: Schumacher, Thomas
Abstract:: Non-destructive testing methods and applications have become of increasing interest due to the worldwide aging and deteriorating infrastructure network. In the field of Civil Engineering, bridges and bridge components as well as non-structural elements such as roadway pavements for example, are affected. In particular, the Acoustic Emission (AE) technique offers...

Flexural steel anchorage performance at diagonal crack locations

Creator:: Triska, Mary Ann
Abstract:: Large numbers of reinforced concrete deck girder bridges that were constructed during the interstate system expansion of the 1950s have developed diagonal cracking in the stems. Compared to the present AASHTO-LRFD standards, the provisions of the 1950s allowed for higher shear stress in the concrete, thus reducing the amount of...

Large-scale laboratory observations of wave forces on a highway bridge superstructure

Creator:: Bradner, Christopher
Abstract:: The experimental setup and data are presented for a laboratory experiment conducted to examine realistic wave forcing on a highway bridge superstructure. The experiments measure wave conditions along with the resulting forces, pressures, and structural response of a 1:5 scale, reinforced concrete model of a typical section of the I-10...

Stress-strain distribution in Douglas-fir beams within the plastic range

Creator:: Ramos, Agustin N., Jr. and Forest Products Laboratory (U.S.)
Abstract:: A method is described to determine the distribution of the bending stresses in a wood beam when some of these stresses exceed the proportional limit. This is used to calculate the position of the neutral axis and the bending strength of some Douglas-fir beams. The calculated values agreed with the...
