Investigation of Full-Scale Performance of Structures?Research Potentials
It is well known that actual, or true, behavior of completed structures does not necessarily conform to often simplified analysis predictions. This may be due to any of several reasons...

Experimental Testing of Laterally Loaded Large Scale Bridge Abutments
The challenges to a bridge analyst in defining abutment boundary conditions and the current state of the practice are presented. Variables within the abutment system are defined and discussed...

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...

Buckling of Cylindrical Storage Tanks Due to Unsymmetric Lateral Wind Load
Non-linear finite element analysis is used to study the elastic stability of cylindrical storage tanks subjected to unsymmetrical loads. These cylindrical shells are assumed to be fixed...

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...

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...

Flexural and Shear Behavior of Combined Concrete and Graphite Epoxy Beams
An experimental and analytical study of six graphite composite beams are presented. Four of the beams incorporated a reinforced concrete slab. The composite action and the effect of concrete...

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....

Full-Scale Testing of Unreinforced Masonry Infill Frame Panels
This paper presents the results of the out-of-plane testing phase of the National Science Foundation Grant BCS 9102347. This phase of the program addresses the out-of-plane response to...

Out-of-plane and In-plane Testing of URM Infills
This paper summarizes the out-of-plane followed by in-plane quasi-static testing of two, full-scale Unreinforced Masonry (URM) Hollow Clay Tile (HCT) infills. The testing is part of a...

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...

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...

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...

Critical Stresses in Nuclear Waste Container Under Normal Handling Conditions
Critical stresses in the pintle, flat tophead, canister shell, the bottom plate and in the weldment of a high level nuclear waste canister are evaluated under a variety of static and dynamic...

Thin-Walled Finite Element for Curved Multicell Box Girders
The generalized Vlasov's thin-walled beam theory was combined with the finite element technique to develop a new curved thin-walled multicell box girder finite element which can model...

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...

Stress Analysis in Concrete with Cooling Pipes
A substructure method of finite element analysis is adopted in this paper to simulate heat transfer and thermal stresses in a concrete dam. The massive concrete structure is cooled by...
