Depressing Traffic Top-Down
Top down construction will permit the City and County of Denver to maintain traffic at two congested intersections while a tunnel is driven below them. The project, which will carry Speer...
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...
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...
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...
Wind Effects and Countermeasures During Erection of a Cable-stayed Bridge
The cable-stayed bridge over the Karnali River in the Kingdom of Nepal was completed in 1992. Extensive wind tunnel testing indicated the likely wind response during construction. Several...
Wind Studies of the Owensboro Bridge, Kentucky
Wind tunnel studies on the Owensboro Bridge are described in this paper, including 1:50 scale sectional model tests and 1:160 scale aeroelastic model tests. Comparisons are presented and...
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...
