Boundary Shear in the Vicinity of River Banks
Some experimental data are presented concerning the distribution of boundary shear stresses in trapezoidal open channels for both inbank and overbank flows. The local shear stresses on...

Building A Barrier Wall Through Boulders
Engineers and contractors conceived a novel approach to a barrier wall at a difficult site near the Niagara River in New York State. The site had been contaminated by a chemical company...

Stiffness of Low Rise Reinforced Concrete Shear Walls
This report, Stiffness of Low Rise Reinforced Concrete Shear Walls, was prepared by the Working Group on the Stiffness of Concrete Shear Wall...

Effect of First-Story Shearwalls on Earthquake-Resistant Buildings
A Practical system for earthquake-resistant building design is described. The system utilizes Teflon sliders at the top of the first story framed shearwalls to carry a portion of the superstructure....

Damage Assessment for Reinforced Concrete Buildings with Shear Walls
This paper tries to establish the analytical method of damage assessment for R.C. buildings with shear walls before or after earthquake. Incremental nonlinear spectrum analysis, using...

Welded Wire Confinement Grids
The invention of a new way to reinforce concrete using high strength welded wire grids, (WWG) increases its earthquake resistance by improved ductility and also opens the way for vast...

CenterCore Strengthening System for Seismic Hazard Reduction of Unreinforced Masonry Bearing Wall Buildings
The CenterCore technique of reinforcing unreinforced masonry walls was developed with the help of a National Science Foundation grant in 1984. The CenterCore strengthening system consists...

Seismic Retrofit of Building Structures with Unreinforced Masonry Infill Walls
The paper summarizes the result of an analytical study conducted by the authors concerning the evaluation of the seismic performance of buildings with unreinforced masonry infills. The...

The Engineer's Role in Reducing Curtainwall Failures
For a variety of reasons, engineers have abdicated responsibility for curtainwall design. Failures of curtainwall components are very common, leading to expensive repairs and even complete...

Dynamic In-Plane Racking Tests of Curtain Wall Glass Components
This paper is concerned with the seismic performance of 'architectural.' or 'non-structural' building elements such as glass elements in curtain wall systems. A pilot study was undertaken...

Structural Response Using Stiffness Decoupler
The structural properties of a new stiffness decoupler developed by Hu, Kirmser and Swartz at Kansas State University, and its applications as an energy absorber and a device to isolate...

Evaluation of Seismic Isolation Schemes for a Historic Building
The U.S. Court of Appeals Ninth District building originally completed in 1905 with an expansion in 1933, suffered damage during the 1989 Loma Prieta earthquake. The building is currently...

Investigation of Diaphragm Walls to Improve Performance, Design, and Construction
As a result of the need for tunnels, underground highways and parking structures, cofferdams, facilities related to the improvement of the environment, etc., there has been a significant...

Analysis of Masonry Walls with Smeared and Discrete Crack Models
To design modern reinforced masonry structures for seismic loads and to evaluate the seismic safety of existing unreinforced masonry buildings, the shear resistance of masonry shear walls...

Seepage Control in Dam Rehabilitation
This paper is concerned with the control of seepage problems which develop in existing dams. It is prefaced with a discussion of attitudes and experiences that have evolved over the last...

Mud Mountain Dam Concrete Cutoff Wall
Mud Mountain Dam is an earth and rockfill flood control dam on the White River. The dam is located approximately 50 km southeast of Seattle, Washington. The dam was constructed in 1941...

Rehabilitation of the Deep Creek Lake Dam
This paper presents the rehabilitation design for upgrading the Deep Creek Lake dam. The Deep Creek dam is a rock fill dam, 92 feet (28 m) high and 1290 feet (393 m) long, and constructed...

An Assessment of Coupled Thermal-Hydrologic-Mechanical-Chemical Processes
A literature review was conducted to determine the state of knowledge available in the modeling of coupled thermal (T), hydrologic (H), mechanical (M), and chemical (C) processes relevant...

Heat Transfer in Vertical Concentric Cylinders in a High Level Nuclear Waste Repository
Modeling free convection heat transfer in an cylindrical annular enclosure is still an active area of research and an important problem to be addressed in the high level nuclear waste...

Object Oriented Design of Finite Element Software for Transient, Non-Linear Coupling Problems
The application of the Finite Element Method to general transient, non-linearly coupled problems calls for high conceptual clarity in software design. In order to attain extendibility...
