Seismic Behavior of Type PR Steel Frames
Type PR(partially restrained 'simple framing') is one of the methods of design specified in the AISC LRFD(1986) Design code for the design of unbraced steel building frames. In this method...

Mechanical Behavior of Dowels Embedded in Concrete
In this paper an experimental investigation on the behavior of dowels embedded in concrete is described. The dowel strength under monotonic forces with two different boundary conditions...

Lateral Load Resisting Systems for Circular Buildings
The design of structural systems to economically limit inter-story drift and building acceleration for circular high rise buildings is presented within the framework of two recently constructed...

Probabilistic Evaluation of Human Perception Threshold of Horizontal Vibration of Buildings (0.125Hz to 6.0Hz)
Vibration perception tests are conducted both for low frequencies of high-rise buildings and high frequencies of low-rise residential buildings. The vibration frequency is varied from...

A Self-Balancing Laminate
A self balancing wood laminate has been developed based on the principle of orthotropic elasticity. Lumber is cut into three sections in the flatwise plane and each side member is turned...

The Effects of Bolt Over-Tightening on Bolted Connections
This paper describes a portion of the research program being conducted on structural connectors which have been over-tightened. Direct-Tension Indicators (DTI) may be specified for use...

Reliability of Light-Gage Metal Joist Hangers
Limit state design equations are formulated to assess the reliability of light-gage metal joist hangers using the results of experimental studies. The design equations are calibrated against...

Fracture Analysis of Bolted Timber Connections
Application of fracture mechanics concepts to splice connections where bolts load timber members perpendicular to the grain is discussed. Attention is given to prediction of the load level...

Proposed Test Method for Determining Bending Yield Moment of Nails
Current engineering design procedures use a yield theory to establish the nominal resistance (capacity) for laterally-loaded nailed connections in engineered structures. In order to develop...

Consequential Fire Loads on Structures
Much less consideration has been given to the performance of modern structural and architectural systems during fires and to the minimization of damage that threatens the integrity of...

Synopsis of a Manual on Structural Fire Protection
Structural Fire Protection : Manual of Practice was published in 1992 by the American Society of Civil Engineers. The Manual has two major parts. Part I (Chapters 1 to 3) introduces the...

Cyclical Behavior of Welded Steel Shear Studs
Four specimens of composite steel and concrete beams were experimentally tested to obtain the cyclical behavior of the welded steel shear stud. This information may be used for the analysis...

Wind Loads on Low Rise Structures: A Survey
Because of the large investment, high rise buildings are usually tested in a wind tunnel to provide the best wind loading information possible. Since low rise structures each represent...

Uplift Resistance of Plywood and OSB Roof Sheathing
A test program to determine the resistance of plywood and OSB roof sheathing to uplift pressures created by wind flowing over a residential roof structure will provide valuable data to...

NDE for Steel Bridges: FHWA Research, Past, Present and Future
Over the last two decades the Federal Highway Administration (FHWA) has sponsored numerous research and development projects in the area of nondestructive evaluation of steel bridges....

AISI-FHWA Model Bridge Test
The Model Bridge Study involved a large experimental test program to evaluate the behavior of a 0.4-scale model of a two-span continuous plate-girder bridge with modular precast prestressed...

Horizontally Curved Steel Bridge Research-Update 2
Theory and data necessary for the development and calibration of an LRFD based curved steel bridge specification do not presently exist. To address these needs, the Federal Highway Administration...

Time-Dependent Load-Distribution Behavior of Parallel-Member Wood Systems
The effect of differential member creep on the load-distribution behavior of parallel-member wood systems is examined. Variability in the creep response of the individual component members...

Field Tests of Railway Bridges
A research program focused on the evaluation of railway bridges has been underway for the past five years. The objectives of a research are as follows: (1) determine the loading spectra...

Cyclic Behavior of Joints Between Steel Beams and Reinforced Concrete Columns
The design and behavior of composite beam-column joints for seismic design are reviewed based on the results of tests. Issues addressed include the strength, deformation, and toughness...
