Site Effects on Strong Shaking and Seismic Risk: Recent Developments and Their Impact on Seismic Design Codes and Practice
The very strong influence of localized poor or 'adverse' geological/geotechnical foundation conditions on patterns and concentrations of damage during a number of recent earthquakes (e.g.:...

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...

Guide for the Design of Prestressed Concrete Poles
With the aim of providing engineers with some basic tools and guidelines for the design of structures, the committee prepares code and policy changes, and to expand input of manufacturers...

Overview - Electrical Substation Structures Design Guide
The ASCE Substation Structures subcommittee of the Committee on Electrical Transmission Structures (CETS) is developing a substation structures design guide. The guide discusses the analysis...

Test Experience with Heavy Angle Dead End Lattice Transmission Towers
During the past three years, the Electric Power Research Institute's Transmission Line Mechanical Research Center has conducted full scale tests on three 500kV heavy angle dead end lattice...

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...

Methods to Control Wind-Induced Building Motions
The wind-induced response of tall buildings can be controlled by global design modifications that can be placed in three broad categories, namely, design changes in structural systems,...

Construction of the Clark Cable-Stayed Bridge at Alton, Illinois
The Clark Cable-Stayed Bridge crosses the Mississippi River at Alton, Illinois. The successful bid by McCarthy Bros/Clark Bridge JV was for the steel alternative. The bridge design included...

Research and Development ? Why bother?
As the world becomes a true global marketplace, the ramifications of this change is felt in all aspects of business. Products and services from around the world are beginning to appear...

Metal Truss Plates: Less than Full-Depth Penetration and Shear Buckling
This paper presents the results of two experimental studies on metal truss plates which are used to join members of wood trusses. The first study investigated the effect that less than...

Externally Stiffened I-Beam to Box-Column Connections
This paper is concerned with I-beam to Box-column connections stiffened externally. Experimental and theoretical findings on full-scale connection models are highlighted. The performance...

Investigating the Behavior of a Lattice Structural Section
Tests were conducted on a fully instrumented lattice section assembled using various connection types (bolted or welded). The results of this study show that bolt slippage can have a major...

ATLSS Connections with Moment Capacity
ATLSS Connections are a family of beam-to-column connections which utilize the self-aligning feature of a specially designed connector and are developed for possible use in an automated...

The Challenge of Housing the Largest Detector
The most innovative part of the structural-civil design of the Superconducting Super Collider (SSC) is that of the underground experimental halls located alongside the 86 kilometer collider...

SDC Detector Foundation Requirements for the SSC
The Solenoidal Detector Collaboration (SDC) detector weighs approximately 32,000 metric tons, and its ability to perform to design specifications is directly related to its internal alignment....

Shear Design Guidelines for Polyester Concrete Using Recycled Plastic
Previous research on the shear behavior of steel-reinforced polymer concrete (PC) beams has been very limited and no efficient design procedures have been proposed. In all the previous...

Fatigue Damage Accumulation Under Stochastic Stress Histories
An extensive simulation study was performed to generate random Gaussian stress time histories from power spectral densities (psd's). The psd's of time histories were selected to represent...

Advances in the Modelling of Long Span Bridges for Wind Effects
The continued development of longer span suspension and cable-stayed bridges has placed increased demand on both the designers and constructors of these structures for a better understanding...

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...

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...
