Experimental results are presented which demonstrate that the use of fluid dampers as add-on devices in moment resisting frames substantially increases damping and reduces seismic story...

A Shear Transfer Model for Floor-To-Wall Connections in Concrete Masonry Structures
Based upon experiments conducted at the Univ of California, San Diego (UCSD) on floor-to-wall connections in concrete masonry structures, a constitutive model was developed for the overall...

Design of Connections in Wood Structures: LRFD vs. ASD
This paper provides a comparison of connection design capacities using load and resistance factor design (LRFD) procedures and allowable stress design (ASD) procedures....

Wood Diaphragm Design Capacities in LRFD Format
Wood diaphragms (horizontal and vertical) have performed well in resisting and transferring lateral forces imposed by major wind and seismic events. Resilient (ductile) behavior of wood...

Wood Bridge Design Using AASHTO LRFD Specifications
A nationwide project to develop a load and resistance factor (LRFD) design edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications...

Serviceability Reliability Analysis of Wood Beams
The effect of creep deformations on the serviceability reliability of single wood beams is investigated. Using stochastic load models and a time-dependent stress-strain relationship, the...

Analysis and Design of SFRC Structural Elements
This paper presents and validates practical methods for flexural, shear and torsional analysis and design of fibrous reinforced concrete structural elements. The effects of both fiber...

In-Situ Determination of the Compressive Stress-Strain Relationship of Multi-Wythe Brick Masonry
In-situ stress-strain relationships of existing multi-wythe brick masonry have been determined by introducing flatjacks into sawcuts made in the exterior wythe of the multi-wythe masonry....

Interfacing Academia and the Practicing Profession
The paper presents a discussion of current topics and instructional methods in structural engineering in the United States. Following a review of typical subject matter in analysis and...

Three-Dimensional Stability Analysis of Carpenter Dam
This paper describes the three-dimensional stability analysis of Carpenter Dam. The presence of keyed construction joints between dam monoliths at Carpenter Dam can significantly affect...

Bond Stress Test on Rock Anchor in Clayey Siltstone
Seventy five rock anchors with design loads of 556 to 2040 kips were required for the 1000-foot long, 125-foot high, concrete gravity, Lake Lynn Dam to comply with current FERC engineering...

Development and Evaluation of Remediation Strategies by Deformation Analysis
Deformation analysis is providing guidance for the most efficient and economical seismic remedial treatments for Mormon Island Auxiliary and Sardis dams. The computer program TARA-3FL...

Adapted Actions Taken at Too Low Shotcrete Quality
A tunnel contract specified quality parameters such as: thickness, compressive strength, adhesive strength, bending tensile strength and residual bending tensile strength for fibre reinforced...

Soil Nailing Technique in Tunnel Support
Authors have developed a new pre-lining method (PASS method) in which thin archshell lining is formed ahead of the tunnel face before the excavation to reinforce the ground. This method...

Investigation in 3-D of Stress Distribution in a Circular Tunnel and Vertical Emplacement Holes Due to Thermal and Overburden Loading in Tuff
Thermal stress and displacement analysis using two 3-D finite element models, one having a course mesh and one having a highly detailed mesh are presented. Results are compared to those...

Mercury Porosimetry Studies on a Natural Fracture
Mercury porosimetry techniques were used to study the effects of stress on the capillary pressure characteristics of a single natural fracture. In addition, permeability measurements were...

A Finite Difference Approach to the Modelling of Thick Bridge Decks
The finite difference method, although well known as an efficient numerical method, was applied in the past, in the case of slabs, only for the solution of thin slabs. In the present study,...

A Generalized Three Invariants Cap Model and its Numerical Implementation to Study Soil-Foundation Interaction
This paper presents a modified cap model that is capable of characterizing cyclic stress-strain behavior of soils and describing variation of shear strength along various stress paths...
