Partial Gravity: Human Impacts on Facility Design
Partial gravity affects the body differently than earth gravity and microgravity environments. The main difference from earth gravity is human locomotion; while the main difference from...
Conservation and Water Supply Planning at Army Installations
The purpose of this paper is to summarize the research being conducted by the U.S. Army Institute for Water Resources in providing technical assistance to the Installation Planning Division,...
Behavior and Design of Gravity Earth Retaining Structures
This paper summarizes recent research on the soil-structure interaction of gravity earth retaining structures and provides new design procedures for these structures. The procedures currently...
Stability Criteria for Revetments
A simplified 'black box' approach is presented for a number of revetment systems for banks and shore protection. The design criteria, based on the physical similarity...
Model Study of the Guadalupe River Bypass Culvert
A hydraulic model investigation of proposed channel improvements for the Guadalupe River Channel was conducted at the US Army Engineer Waterways Experiment Station in Vicksburg, Mississippi....
Rate Effects on Fracture of Concrete
An analytical and experimental investigation of mode I (tensile and mixed mode (combined tensile and shear) fracture of concrete subjected to impact loading was conducted. The rate of...
Measurement of Impact Fracture Toughness of FRC
Instrumented impact tests have been in use since the early eighties for studying the fracture characteristics of cement-based composites at high rates of loading. While significant progress...
Wind Bracing
This chapter discusses the structural design of the bridge with regards to wind forces....
Load-Permit Truck Operations in New York State
This paper presents the results of a survey of indivisible-load permit vehicle operations in New York State. The survey was conducted in the context of an investigation into the impacts...
Panel-Sheathed Shear Walls ? Past and Future
In order for a building to resist the lateral forces caused by wind or earthquake, it is necessary that the building include a lateral force resisting system. When the walls are designed...
Parametric Analyses of RC Shear Walls by FEM
In this paper, nonlinear behavior of reinforced concrete shear walls is studied by using the finite element analysis. We applied numerical analyses to a wide range of parameters, such...
Mitigation of Wind-Induced Vibration of Tall Buildings
This paper summarizes a detailed study of the sensitivity of building acceleration to changes in structural stiffness, mass and damping and to the eccentricities in the centers of stiffness...
Aerodynamic Methods for Mitigating Wind-Induced Building Motions
Excessive wind-induced motions of tall buildings most frequently result from vortex shedding induced across-wind oscillations. This form of excitation is most pronounced for relatively...
Full-Scale Measurement on Chiba Port Tower
Chiba Port Tower is a tall tower, 125m high, with a rhombus shaped plan. All of the surfaces are covered with half mirror glass. On the top of the tower, a 'Tuned Mass Damper'...
Unsteady Aeroelastic Base Moments on a High-Rise Building
To consider aeroelastic instabilities of prismatic structures in winds, i.e., vortex induced vibrations or galloping oscillations, unsteady aeroelastic forces must be investigated as the...
Inelastic Performance of Single-Story Masonry Shear Walls
Twenty-two story-height reinforced masonry shear walls have been tested to examine the influence of the applied axial stress, and the amount of vertical and horizontal reinforcement on...
Vibration Control Damper Using Sloshing of Water
The objective of this study is to develop a method of reducing wind-induced vibration of long-period structures utilizing sloshing of water in tanks added to the upper part of the structures....
Bond and Dowel Action of a Main Bar in a RC Beam
The bond and dowel action are analytically treated independently on each other in most cases. The bond behavior may be, however, much affected by the dowel action in structural members....
ATC 14: A Methodology for the Seismic Evaluation of Existing Buildings
A new method for evaluating the seismic resistance of existing buildings has been developed based on the historic performance of buildings in past major earthquakes. This methodology identifies...
Comparison of Slitted and Non-Slitted R. C. Shear Walls With Boundary Elements Under Horizontal Forces
This paper compares the differences of aseismic behaviours between slitted and non-slitted shear walls under horizontal forces. There are 5 specimens for slitted shear walls and another...
