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,...
The Normandie Bridge
The Normandie Bridge will have one of the longest cable-stayed spans in the world, i.e. 856 m long. This paper briefly describes the design of the bridge, with the concrete access spans...
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...
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...
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...
Modelling of Extended Endplate Bolted Connections
A methodology based on finite element modelling is examined to study the behaviour of extended endplate bolted connections. ANSYS (Rev. 4.4), a large scale finite element program is used...
Creep Analysis of Composite Steel-Concrete Members with Deformable Connectors
The long-term analysis of composite steel-concrete beams with elastically deformable connectors is presented. The basic integro-differential equation governing the problem is solved by...
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...
Cut and Cover Construction of the SSC Injector Tunnels
The injector system of the Superconducting Super Collider (SSC) constitutes the string of tunnels where protons are accelerated to near the speed of light and injected into the main collider...
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....
An Overview of Shotcrete Usage on the SSC
Shotcrete has been widely used on the Superconducting Super Collider for initial support of tunnel excavations in both the strong and weak rock formations encountered. Different types...
Limit States Analysis of Masonry Arches
The limit states analysis of masonry arches, heretofore used only for the analysis of hinging mechanisms within the arch ring, is shown to have wider applicability. Lower and upper bounds...
A Peice-wise Linear Evaluation of Masonry Infills Subjected to Out-of-plane Seiesmic Drift
This paper summarizes the out-of-plane testing and analytical modeling of a full-scale unreinforced masonry (URM) infilled frame and a bare frame without infilling. The testing was part...
Seismic Strengthening of URM Buildings with Steel Bracing
Unreinforced masonry (URM) buildings with large open fronts are extremely vulnerable to seismic inputs posing serious life safety hazard. Steel bracing systems have been used to upgrade...
Load Carrying Capacity of SPC Composite Column
This paper reports the result of beam column test of a new type composite columns. High-strength precast-concrete panels (hereafter denoted as PCa-panels) are fixed to the steel square...
Damping Systems for Controlling Wind Induced Motions of Structures
This paper presents the state-of-the-art in damping systems for controlling wind induced motion of structures and their applications in the U.S. and Japan. Both passive and active systems...
Characterization of an ER Active Member
In the presence of strong electric fields (kV/mm), electrorheological (ER) materials change form viscous fluids to yielding materials. The class of ER materials used in this study have...
Wind Deflection Probability Analysis
A statistical analysis is performed which analyses the probability of various magnitudes of deflections of a cable-stayed roof occurring due to wind uplift. Extensive wind analyses were...
