Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...
Moment Rotation Curves for Double Framing Angles
Moment-rotation curves for bolted framed steel connections are derived from force-deflection data obtained from laboratory tension and compression tests of angle segments. These derived...
Beam-Columns
The Fourth Edition of the SSRC Guide presents a state-of-the-art information on beam-columns for use by specification writers, researchers, and designers. The present paper is an extremely...
Effect of Connector Spacing on Double Angle Compressive Strength
The 1986 AISC 'Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings' includes new rules affecting the design of built-up members...
Reliability Revision for Structures in Service
Models of structural reliability are called upon to provide not only initial estimates of safety, but also revised estimates reflecting new information on the structure as it becomes available....
Fracture-Mechanics-Based Fatigue Life Estimate
Fatigue lives of tee-shaped weldments are estimated using fracture mechanics concepts and crack growth rate data. Fracture mechanics is used to develop an approximate expression for stress...
Aluminum Orthotropic Bridge Deck Verification
This paper reports tests conducted to evaluate an aluminum orthotropic deck. Approximately 60 welded T-joints with 6061-T6 stems and 5456-H321 plate were subjected to flexural fatigue...
Fatigue Design Criteria for Welded Steel Details
A review of fatigue data and reassessment of the 1983 fatigue specification resistance functions has been conducted. Since the AASHTO specification fatigue resistance provisions were introduced...
A Fatigue Study of Prestressing Strand
Strand fatigue data reported in the literature and also from recent tests were combined to form a data base of strand fatigue data which was analyzed using regression analysis techniques....
Fatigue Strength of Welded Wire Fabric
Long life fatigue tests were made on 12 concrete slabs reinforced with large diameter, Grade 75, deformed welded wire fabric. The specimens simulated, to full scale, conditions in a bare...
Axial Fatigue Model for Wire Rope Strand
A numerical fatigue model for cables and rope strand subjected to fluctuating axial tension has been developed. This model determines the maximum wire nominal and Hertz contact stresses,...
Base Isolation for Reinforced Concrete Structures
A recent experimental program has been carried out at the Earthquake Simulator Laboratory of the Earthquake Engineering Research Center in which a 1/5th scale reinforced concrete structural...
New Directions in the Application of Probabilistic Concepts in the Seismic Analysis of Nuclear Power Plants
During the last 8 years, probabilistic concepts have been used in the seismic analysis of nuclear power plants. Probabilistic risk assessment (PRA) has been the primary vehicle for performing...
Projectile Penetration Into Reinforced Concrete and Steel Targets
This paper presents brief preliminary results of a research program sponsored by the Air Force Weapons Laboratory (AFWL) to investigate the interaction of 30-mm cannon projectiles with...
Rescuing the Everglades
After a century of trying to control Florida's Everglades, water management officials have decided that cooperating with nature is better. A new strategy known as the Rainfall...
Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...
Highway Accident Collision Diagrams on a Microcomputer
Collision diagrams of highway accidents are schematic exhibits that illustrate the location of each accident with respect to the highway geometric features. The types of accidents; such...
Selected Papers from the Chinese Journal of Geotechnical Engineering ?1985
This book contains English translations of 19 articles selected from the Chinese
Twisting in the Wind
Wind tunnel tests are being used increasingly to test the aerodynamic stability of bridges. Many designers think these tests should be used early in the conceptual design stage, rather...
Taipei Trade
The appearance of this building is remarkable�so were the cost savings. A design change form rigid shear walls to a ductile frame helped keep construction of Taipei's World...
