ASCE GUIDE for Design of Guyed Transmission Structures
This paper describes the contents of a new ASCE guide for the selection and design of guyed electrical transmission structures. Guyed transmission structures present unique analysis and...

Construction of the Baytown Bridge, Houston
Connecting Baytown and LaPorte, the Baytown Bridge is a twin structure with four traffic lanes each. Its structure is designed as a cable-stayed bridge with concrete towers and composite...

Seismic Behaviour of Tall Guyed Telecommunication Towers
This paper presents results of a detailed numerical modelling study of two guyed telecommunication towers subjected to seismic excitation: a 107-m (350 ft) tower with six stay levels,...

Transient Response of Guyed Telecommunication Towers Subjected to Cable Ice-Shedding
This paper presents the results of a numerical study of the transient response of guyed telecommunication towers subjected to sudden ice shedding from the guy wires. Detailed nonlinear...

Ultimate Strength of R/C Cooling Tower Shell
Reinforced concrete(R/C) cooling towers are the largest, thin shell structures. It is important to assess the ultimate strength of R/C cooling tower shells subjected to wind load. In the...

Repair of a Cracked Cooling Tower Shell Based on Numerical Simulations
The present condition of a 30 years old cooling tower shell made of reinforced concrete is characterized by a relatively large number of long, thermally induced meridional cracks. For...

Uplift Load-Displacement Behavior of Grillage Foundations
Full-scale field tests were conducted on steel grillage foundations for lattice transmission line towers that had been in place since 1929, 1947, and 1958. A total of eight tests were...

Pittsburgh Goes International
The size of the new $785 million Pittsburgh International Airport—900 developed acres—is twice the size of the city's Golden Triangle business district but occupies only a...

Aeroelastic Study of Long Span Suspension Bridges: the Messina Crossing
This paper deals with wind actions on long-span suspension bridges. Particular reference is made to the Messina Strait Crossing. Problems encountered in this study, both for deck and towers,...

Wind Resistant Design Manual for Highway Bridges
'Wind resistant design manual for highway bridges in Japan' has been published in 1991. Before publication of this manual, there were no authorized wind resistant manuals which can be...

Superlong Cable-Stayed Bridges
Superlong cable-stayed bridge span is defined as one over 1000 meters. Problems requiring special attention regarding these bridges are discussed, namely: excessive cable sag; high axial...

Reliability-Based Design of Transmission Towers Under Wind and Ice Loadings
This study suggests a practical but rational approach for the development of reliability-based LRFD criteria for transmission towers under wind and ice loadings in Korea. Based on available...

Buckling of Guyed Towers
The buckling load of a column guyed in a plane by symmetric guy wires is considered. The column is built-in at the ground, supported at the top by guy wires, and is loaded by a vertical...

Research of the Limit Function About Imperfection and the Approximately Calculating Method of the Internal Forces of Hyperbolic Cooling Tower
The authors use the finite elemental program, which made by themselves and makes use of finite element method with rotational shell, to calculate the deformation in hyperbolic cooling...

Computer-Aided Guyed Tower Analysis for the Rehabilitation of TTI Tower, Baltimore
A large guyed television tower owned by Television Tower Inc. of Baltimore is currently being analyzed in order to evaluate the capacity of the tower to support additional broadcasting...

Establishment of a Habitat Monitoring Program to Assess Potential Impacts of Diversion of POTW Effluent
As part of the permitting process for a gas-fired power plant, the environmental impacts of diverting POTW effluent from the receiving water for cooling tower makeup was investigated....

A Dome To Remember
Under intense pressure from all sides, a trio of engineering and architectural firms working in San Antonio, Tex., turned the political coal of a stadium everyone wanted to build (but...

Double Diamonds: New Brand for a Texas Bridge
Double diamond towers, distinctive as a cattle brand but tall as a 44 story building, have reached landmark status on the Texas Gulf Coast even though the bridge they will carry won't...
