Preliminary Dynamic Analysis of a Railroad Bridge
Basic Behavior of Composite Sections Made of Concrete Slabs and Graphite Epoxy Beams
This research presents the analytical and experimental study of the basic behavior of composite sections made of concrete slabs and graphite/epoxy beams. The study also includes the testing of bond between concrete and ...
Nonlinear Bridge Abutment , Verification, and Design Curves
This report presents an efficient approach to evaluate the nonlinear translational spring stiffnesses to represent seat-type abutments. The applicability of previous studies is limited because such studies are incapable ...
Seismic Retrofit of Column-Pier Cap Connections in Bridges in Northern Nevada
The purpose of this study was to evaluate and improve the seismic resistance of the column-pier cap connection of bridges with inadequate column bar development and no shear reinforcement in the joint region. The study ...
Effects of Axial Force on Frequency of Prestressed Concrete Bridges
The purpose of the study presented in this report was determine if vibration frequencies of prestressed concrete member can be used to establish prestress losses. A post-tensioned concrete bridge (called the Golden Valley ...
An Evaluation of the Current Caltrans Seismic Restrainer Design Method
The primary objective of this study was to develop an understanding of the implications of the current Caltrans hinge restrainer design procedure. Two aspects of the problem were studied. One was the effects of changing ...
Response of Layered Deposits to Traveling Surface Pressure Waves
The response of a soil deposit subjected to moving surface pressure loads is of interest in various areas of engineering and physics. The free field response is required in the design of blast structures. Most of the ...
Liquefaction and Residual Strength of Sands from Drained Triaxial Tests
The state of knowledge with regard to static and cyclic liquefaction has progressed tremendously since the mid-1960s. In fact, it is generally accepted, based on the steady-state concepts of Casagrande, Castro, and Poulos ...
Liquefaction and Residual Strength of Loose Sands from Drained Triaxial Tests
The state of knowledge with regard to static and cyclic liquefaction has progressed tremendously since the mid-1960s. In fact, it is generally accepted, based on the steady-state concepts of Casagrande, Castro,and Poulos ...
