Hi-Tech Seismic Rehabilitation of `Casino De Montreal'
The existing eight-story steel structure, built during 1966, lacked in lateral earthquake resistance and ductility requirements of the current building code. Introduction of friction-dampers...

Anchorage of Non-Metallic Prestressing Tendons
Experimental confirmation tests were conducted to evaluate mechanical and epoxy socketed anchors for fiber reinforced plastic (FRP) prestressing tendons. The studies found that a parabolically...

Seismic Response of Concrete Tilt-Up Systems
A Summary of the measured dynamic response of a one-story, till-up warehouse located in Hillister, California, is presented. Acceleration and relative displacement histories may be used...

Seismic Retrofit of R/C Columns with Inadequate Lap Splices
This paper presents experimental results on the use of rectangular steel jackets to improve the seismic performance of rectangular steel jackets to improve the seismic performance of rectangular...

Seismic Renewal of Civil Infrastructure Systems
Almost all civil infrastructure systems are vulnerable to natural hazards such as earthquakes. The paper presents a broad perspective of the research needs for seismic renewal of the infrastructure...

Steady-State Analysis of Buckle Propagation
A novel finite element technique for the analysis of buckle propagation in pipelines is presented. The propagation pressure, propagation profile, the state of stress, and deformation during...

A Generalized Approach to the Local Stability of Stiffened Plates: Part I?Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...

A Generalized Approach to the Local Stability of Stiffened Plates: Part II?Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...

LRFD vs. ASD for Wood Structures
There is a growing preference within the structural engineering community for the adoption of reliability-based load and resistance factor design (LRFD) procedures in lieu of traditional...

Blast Demolition of Reinforced Concrete Industrial Chimneys
On some of recently demolished chimneys, transient measurements were taken, in the vicinity of the tilting hinge, during the process of falling down. Thus, corresponding dynamic computational...

Fabric Roof Design Responds to New Technologies
A combination of newer synthetic materials and advanced structural design technologies have given contemporary tensioned fabric roofs vastly improved energy performance and far greater...

Nonlinear Behavior of Northlight Reinforced Concrete Shells
The behavior of northlight shells is very sensitive to the boundary conditions at the top and bottom edges of the shell. The aim of this paper is to investigate the structural action of...

Efficient Nonlinear Analysis of Column-Supported Cylinderical Shells
This paper presents a finite element methodology for the study of geometrically nonlinear behavior of column-supported cylinder. Due to the discrete nature of the column supports, the...

Elasto-Plastic Buckling Design for Shallow Cylindrical Shells under External Pressure
Pressures providing elastic-plastic buckling conditions for thin shallow cylindrical shell panels are presented. Classical simple support boundary conditions have been adopted for the...

The Body Language of Tensile Structures
Considered to be a 'body' and its visual appearance as 'non verbal, intuitable information,' a building has a Body Language that is employed as a primary mode. Presented is an intuitive...

Damage Tolerance Analysis in Structural Rehabilitation
The rehabilitation of existing structures requires an evaluation by the structural engineer of past performance to determine the extent of existing damage. Following evaluation of the...

Nonlinear Earthquake Analysis of Concrete Gravity Dams Including Sliding
The sliding stability of a concrete gravity dam during a design earthquake must be investigated to assess the seismic safety of the dam. A new numerical procedure for solving the equations...

Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...

Modeling the Seasonal Circulation in Massachusetts Bay
An 18 month simulation of circulation was conducted in Massachusetts Bay, a roughly 35 m deep, 100?50 km embayment on the northeastern shelf of the United States. Using a variant of the...
