Load Duration and System Effects in LRFD for Wood Construction
The wood industry is developing a Load and Resistance Factor Design (LRFD) speciification for wood construction using probabilistic concepts. An analysis based on statistical models for...

International Harmonization of Reliability-Based Timber Engineering Design Codes
An overview is presented on reliability-based timber design code activities in various major timber producing and consuming countries. The overview is based on information generated through...

Serviceability Analysis of Wood Beams with Creep
The effect of creep deformations on the serviceability reliability of single, dimension lumber wood beams is examined. A viscoelastic stress-strain relationship is used to model the time-dependent...

In-Plane Non-Linear Random Vibration of Composite Plates
Filamentary composite structural components used in engineering applications are usually subjected to stochastic loads. Composites have strongly anisotropic properties and display significantly...

Experimental Study of the Transient Temperature Distributions in Concrete
A small scale, preliminary experimental effort to quantify the randomness of the thermal diffusivity of concrete has been undertaken. Two sets of cylinders have been instrumented with...

Some Modeling and Analysis Techniques for Wave Propagation in Random Media
Some mathematical modeling techniques for the problem of wave propagation in randomly imperfect periodic medium are reviewed: multiscale formulation and random evolution modeling. These...

Fabric Related Probabilistic Model for Granular Materials
A new anisotropic noncoaxial incremental constitutive model for granular materials (Jahedi et al., 1990) was developed, in which a Fabric reconstruction factor '?+',...

Stochastic Modeling of Short Fiber Reinforced Composites?A Review
Since the early 1960's, an extensive research and development has been carried out with fiber reinforced cements and concretes. Modeling of such heterogeneous material is still in the...

An Advanced First-Order Method for System Reliability
This paper proposes an iterative first-order method for accurate estimation of the joint failure region of two nonlinear limit states. Current methods use either a first-order approach...

Construction Loads on Floors: Results of a Survey
A survey of post-shorting construction loads on floors of multi-storey buildings is described. The estimated parameters of a probabilistic model of the peak (transient) loads are reported....

A Two-Stage Safety Assessment Methodology for Construction Activities
The control of construction activities requires the evaluation of the condition of the control attributes of interest. In order to develop the required methodology, a model of the construction...

Optimal Configuration for Fiber Reinforced Composites under Uncertainties of Material Properties and Loadings
Fiber reinforced composite structures could be designed by selecting proper fiber orientation in structures to suit specified desires for strength, stiffness or other mechanical properties....

Holistic Approach to Irrigation Management in Developing Countries
Sound development of irrigation and drainage projects in developing countries is a continuing need to reduce hunger, environmental degradation and excess population growth; and to promote...

Metrication of Construction?A Message to the American Society of Civil Engineers
The author discusses the reasons for metrication of the U.S. construction industry, describes the Canadian experience in this area, and outlines the necessary steps to alleviate the metrication...

A Monumental Task
The geotechnical consultants, structural engineer and contractor combined to overcome difficult soils, underground subway structures and buried utilities when building the foundations...

Cranes, Concrete, Construction...and Computers
Computers are already firmly entrenched in the design process. Now, they're touching all corners of construction. Applications range from traditional project management tasks...

The Evolution of an Environmental Monitor
After more than 40 years of planning, litigation, design and construction, one of the nation's most controversial highway projects is finished. The completion earlier this...

Container Terminal Planning: 2001
This paper highlights the technical, yet practical planning process and operations research methodologies used by the country's largest containership company to guide 21st Century container...

Gate Maritime Wharf and Intermodal Facility
Gate Maritime Properties (GMP) is a small private port located in Jacksonville, Florida. In November of 1989, Gate signed a long-term lease agreement with the U.S. Department of the Navy...

New Cruise Terminal for San Francisco
A new international Cruise Terminal is being developed at Pier 30-32 in San Francisco, to replace present inadequate facilities at Pier 35. The Cruise Terminal will be developed as part...
