The Clifton Suspension Bridge is an icon of the City of Bristol, England and it recently celebrated its 150th Birthday. It spans the beautiful and picturesque Avon Gorge and connects Bristol with North Somerset. The structure is a Grade I listed structure and attracts visitors from across the world every year. Today the bridge's upkeep is entirely funded by tolls, a practice that hasn't changed since it opened to the public in 1864. The bridge is manned and open 24 hours a day, 7 days a week all year round.

The seismic response of deck arch bridges with and without track constraints were calculated, taking the uniform longitudinal input by El-Centro wave excitation as an example
The seismic response of deck arch bridges with and without track constraints were calculated, taking the uniform longitudinal input by El-Centro wave excitation as an example. The analysis focused of structural deformation and the symmetry of bridge structures, thus the pier top displacement responses of the left junction pier and left-span column piers (piers P6~P13 in Figure 3) were compared. This paper also focuses on the effect of seismic activity on track–bridge longitudinal response for CWR on bridges in a seismically active zone
A response analysis of overground pipelines under multi-component random ground . The ground motion is modelled as a stationary random process
A response analysis of overground pipelines under multi-component random ground motion is presented for a parametric study. The pipeline is considered. to be either extended longitudinally or to intersect and form a T shape. The ground motion is modelled as a stationary random process. Mean square responses of the pipeline are obtained by frequency domain spectral analysis. Responses are also obtained with the help of a quasi-static analysis for random ground motion, for pipelines whose natural frequencies are well beyond the dominant frequencies of excitations. As a result, the mass of the pipe and fluid inside and the support masses are lumped at the nodes.
Since its release, the PEER Ground Motion database has proved to be very popular among engineers in the . Modern approaches to assessing seismic performance of infrastructure rely on good information about likely ground shaking at a site.
Since its release, the PEER Ground Motion database has proved to be very popular among engineers in the earthquake-related disciplines, who are increasingly using it for selection and modification of records to analyze computer models of buildings, bridges, and other facilities. The database is now cited as a primary source of ground motion records in the latest revision of the Building Seismic Safety Councils NEHRP Recommended Provisions.
